I have envisioned and have implemented to completion the publication of a series of

Clinical Practice Guidelines on the major procedures and topics of Obstetrics and Gynecology.This is in consonance with the theme of my Presidency, Babae, Kalusugan Mo, Katungkulan

Natin. This is the Clinical Practice Guidelines on Normal Labor and Delivery and is the Second

Edition of this Publication, 2009.

In the role of the POGS to provide its members with updates, current and standard

practice recommendations and guidelines, this publication will fulfill the objective of continuing

education and implementation of refinements in Obstetrics and Gynecology. In keeping with the

highest standards of care, the Level and Grades of Clinical Practice/Recommendation have

been adopted for every recommendation that is completed and decided.

In the process of the formulation of the guideline/recommendation, the entire

membership of the POGS was consulted. I take special effort to thank the AdHoc Committee on

Clinical Practice Guidelines, headed by its Chair, Dr. Efren J. Domingo for the unceasing

tireless effort to complete this publication. I also gratefully acknowledge the Chairs and Training

Officers of the Residency-Accredited Hospitals, the Technical Working Group, and the CME

Committee.

It becomes easy, dignified and scientific to conduct the practice of Obstetrics and

Gynecology specifically on Normal Labor and Delivery. Now, the Clinical Practice Guidelines on

Normal Labor and Delivery will hope to update and make the practice current and responsive to

world-class standards and make the patients under our care deserving of the trust andconfidence that we, Obstetricians, impart with utmost care and compassion.

EFREN J. DOMINGO, MD, PhD

Chair, AdHoc Committee on the Clinical Practice Guidelines, 2009

The Clinical Practice Guidelines on Normal Labor and Delivery is the Second Edition of

this Publication, 2009. The Philippine Obstetrical and Gynecological Society, (Foundation), Inc.

(POGS), through the AdHoc Committee on Clinical Practice Guidelines initiated and led to

completion the publication of this manual in plenary consultation with the Residency Accredited

Training Hospitals Chairs and Training Officers, The Regional Board of Directors, The Board of

Trustees, The Task Force on the Mangement of Normal Labor and Delivery and the Committee

on Continuing Medical Education.

This publication represents the collective effort of the POGS in updating the clinical

practice of Obstetrics and Gynecology, specifically on Normal Labor and Delivery, and making it

responsive to the most current and acceptable standard in this procedure. A greater part of the

inputs incorporated in this edition are the contributions originating from the day-to-day academic

interactions from the faculty of the different Residency-Accredited Hospitals in Obstetrics andGynecology in the country.

This Clinical Practice Guideline on Normal Labor and Delivery is envisioned to become

the handy companion of the Obstetrician-Gynecologist in his/her day-to-day rendition of quality

care and decision making in managing the Obstetric patient. This is also envisioned to provide

the academic institutions in the country and in Southeast Asia updated information and Normal

Labor and Delivery treatments being practiced in the Philippines.

Profound gratitude is extended to all the members of the POGS, the Chairs and Training

Officers of the Residency-Training Accredited Institutions, the Regional Directors, The Task

Force on Normal Labor and Delivery Reviewers/Contributors, The CME Committee members,

the 2009 POGS Board of Trustees and the educational grant provided by Sheeling Pharma.

DISCLAIMER, RELEASE AND WAIVER OF RESPONSIBILITY

This is the Clinical Practice Guidelines (CPG) on Normal Labor and Delivery, Second Edition,November 2009.

This is the publication of the Philippine Obstetrical and Gynecological Society, (Foundation), Inc.(POGS).

This is the ownership of the POGS, its officers, and its entire membership. The obstetrician gynecologist, the general practitioner, the patient, the student, the allied medical

practitioner, or for that matter, any capacity of the person or individual who may read, quote, cite,

refer to, or acknowledge, any, or part, or the entirety of any topic, subject matter, diagnostic condition

or idea/s willfully release and waive all the liabilities and responsibilities of the POGS, its officers

and general membership, as well as the AdHoc Commiittee on the Clinical Practice Guidelines and its

Editorial Staff in any or all clinical or other disputes, disagreements, conference audits/controversies,

case discussions/criticquing.

The reader is encouraged to deal with each clinical case as a distinct and unique clinical conditionwhich will never fit into an exact location if reference is made into any or all part/s of this CPG.

The intention and objective of this CPG is to serve as a guide, to clarify, to make clear the distinction.It is not the intention or objective of this CPG to serve as the exact and precise answer, solution and

treatment for clinical conditions and situations. It is always encouraged to refer to the individual

clinical case as the one and only answer to the case in question, not this CPG.

It is hoped that with the CPG at hand, the clinician will find a handy guide that leads to the a clue, to a

valauable pathway that leads to the discovery of clinical tests leading to clinical treatments and

eventually recovery.

In behalf of the POGS, its Board of Trustees, the Adhoc Committee on The Clinical PracticeGuidelines, 2009, this CPG is meant to make each one of us a perfect image of Christ, the Healer.

I. DEFINITION OF LABOR

o In Latin, the word labor means a troublesome effort or suffering. Another term forlabor isparturitionwhich comes from the LatinParturire to be ready to bear young andis related topartus to produce. To labor in this sense is to produce.

o Labor is a physiologic process that begins with the onset of rhythmic contractions whichbring about changes in the biochemical connective tissue resulting in gradual effacement

and dilatation of the cervix and end with the expulsion of the product of conception.o The contractions are characterized by a progressive increase in frequency, intensity and

duration.

o Labor is a clinical diagnosis.o Cervical dilatation in the absence of uterine contractions suggests cervical incompetence,

whereas uterine contractions without cervical changes does not meet the definition of

labor.o The criteria for the diagnosis of labor include:

1. Uterine contractions (at least 1 in 10 minutes or 4 in 20 minutes) by direct

observation or electronically using a cardiotocogram2. Documented progressive changes in cervical dilatation and effacement as observed by

one observer

3. Cervical effacement of > 70-80%4. Cervical dilatation > 3cm

o The diagnosis of labor is traditionally based on clinical findings and it is particularlydifficult to make with confidence especially to those presenting in the early stage of

labor.o A serious digital cervical examination must be done in a patient with persistent uterine

contractions.

o The majority of reported criteria for labor in literature agree that there must be cervical

changes brought about by regular uterine contractions. However, they differ in thenumber of observed contractions, the cervical dilatation and the start of labor, and the

degree of cervical change necessary for the diagnosis.

II. FIRST STAGE OF LABOR

A. MONITORING OF FETAL WELL-BEING DURING NORMAL LABOR

o

The monitoring of the fetal heart rate in labor aims to identify hypoxia before it issufficient to lead to long term poor neurological outcome for babies.o Auscultation of the fetal heart rate during labor was the predominant method of

assessment since the start of the 20th century. Auscultation is done at regular intervalsusing a hand held Doppler device, Pinard (special trumpet shaped device) or fetal

stethoscope.o Since the introduction of the electronic fetal heart rate monitoring in the 1960s, the idea

of receiving continuous data by electronic fetal monitoring (EFM) was thought to besuperior to intermittent auscultation. Its use though is limited to institutional births.

Recommendations:

o Royal College of Gynaecologists (RCOG) / National Institute for Health and ClinicalExcellence (NICE) Guidelines recommend that intermittent auscultation be undertaken

every 15-30 minutes in the 1ststage of labor and every 5 minutes in the 2ndstage of laborat least 30 seconds after each contraction.

o Intermittent auscultation is recommended as a minimum for women who at the onset oflabor are identified as having low risk of developing fetal compromise. (Grade A)

o Admission cardiotocography (CTG) is not recommended for healthy women at term inlabor in the absence of risk factors for adverse perinatal outcome, as there is no evident

benefit. (Grade A)

o Continuous EFM should be recommended when either risk factors for fetal compromisehave been identified antenatally, at the onset or during labor. (Grade A)

o There is universal acceptance that the fetus in labor is at particular risk from hypoxicdamage. It is therefore the goal of intrapartum fetal surveillance to detect potential fetaldecompensation and to allow timely and effective intervention to prevent

perinatal/neonatal morbidity and mortality.

B. INDUCTION OF LABOR

Definition:

o Induction of labor is defined as an intervention designed to artificially initiate uterinecontractions leading to progressive dilatation and effacement of the cervix and birth ofthe baby (RCOG, 2001).


16/51

Recommendations:

General

o Assessment with documentation prior to starting the induction should include:! confirmation of parity

! confirmation of gestational age

! presentation! Bishops score

Table 1. Bishops Preinduction Cervical Score System

uterine activity! nonstress test

o Induction of labor is a major intervention and should only be implemented on a validindication. (Level I, Grade C).The indication for induction should be documented.

Confirmation of Term Gestation

(ACOG Practice Bulletin #230, November 1996)

Fetal heart tones have been documented for 20 weeks by nonelectronic

fetoscope or for 30 weeks by Doppler

The passage of 36 weeks since a serum or urine human chorionicgonadotropin (HCG) pregnancy test was found to be positive

Ultrasound measurement of the crown-rump length at 6-11 weeks

gestational age (GA) that support a current GA equal =/> 39 weeks

Ultrasound measurements at 13-20 weeks GA that supports a clinicallydetermined GA equal =/> 39 weeks.

17/51

o Assess cervical ripening with the use of Bishops preinduction score system (Table 1).o The induction of labor should be administered only in a hospital setting, particularly in a

labor room under the responsibility of an obstetrician. It should also be monitored by a

physician familiar with the effects of induction agents and able to detect and respond tomaternal and fetal complications.

Methods of Induction of Labor

OXYTOCIN

o Oxytocin augmentation is a major intervention and should only be implemented on avalid indication.(Level I, Grade C).

o Cervical dilation, parity, and gestational age are predictors of the dose response tooxytocin for labor stimulation (Level 4).

o Women in whom labor induction is indicated may be managed by either a low or highdose oxytocin regimen. (ACOG, Grade A).

o The purpose of oxytocin administration is to effect uterine activity that is sufficient to

Induction is indicated when the continuance of pregnancy may no longer be

advisable in the following clinical circumstances:

1. Gestational hypertension

2. Preeclampsia, eclampsia

3. Prelabor rupture of membranes4. Maternal medical conditions (e.g., diabetes mellitus, renal disease, chronic

hypertension)

5. Gestation !41 + 1/7 weeks6. Evidence of fetal compromise (eg, severe fetal growth restriction,

isoimmunization)

7. Intraamnionic infection8. Fetal demise

9. Logistic factors for term pregnancy (e.g., history of rapid labor, distancefrom hospital, psychosocial indications)

Contraindications for Labor Induction

1. Malpresentations (e.g., transverse, breech)

2. Absolute cephalopelvic disproportion

3. Placenta previa4. Previous major uterine surgery or classical cesarean section

5. Invasive carcinoma of the cervix

6. Cord presentation

7. Active genital herpes8. Gynecological, obstetrical, or medical conditions that preclude vaginal

birth

9. Obstetricians convenience


18/51

produce cervical change and fetal descent while avoiding uterine hyperstimulation andfetal compromise.

o It is recommended that oxytocin be ordered and recorded in milliunits (mU)/minute.o Oxytocin should be delivered through a secondary intravenous (IV), piggy-backed to the

main IV line as close to the venipuncture site as possible.o

When induction of labor is undertaken with oxytocin, the recommended regimen is astarting dose of 1-2 mU/minute and is increased at intervals of 30 minutes or more. Theminimum dose should be used and this should be titrated against uterine contractions

aiming for a maximum of 3 to 4 contractions every 10 minutes (RCOG, Grade C).

o Adequate contractions may be established at 12 mU/min and the licensed maximum doseis 20 mU/min (RCOG, Grade C). If higher doses are used, the maximum dose usedshould not exceed 32 mU/min (RCOG, Grade C).

o To reduce error, a standard dilution should always be used (for example, 30 IU in 500 mLof normal saline; hence 1 mL/hour =1 mU/minute (RCOG, Grade C).

o Regular observations of uterine contractions and fetal heart rate should be recorded every15 to 30 minutes and with each incremental increase of oxytocin.

o

Continuous intrapartum electronic fetal monitoring is recommended when oxytocin isbeing used for induction of labor.o If fetal heart rate abnormalities or tetanic contractions develop, the infusion should be

stopped, intrauterine resuscitation measures initiated and the situation re-evaluated before

restarting the infusion.o If restarting the oxytocin, it may be necessary to lower the dosage and lengthen the

interval between subsequent increases.

o If intrauterine resuscitation is successful, oxytocin may be restarted at 1/2 the last doseo Should uterine hyperstimulation occur without evidence of fetal compromise, then

decrease the oxytocin infusion rate and re-evaluate situation.

Signs and symptoms of hyperstimulation include:

Five contractions in 10 minutes or more than 10 contractions in 20 minutes

Hypertonus contraction(s) lasting more than 120 seconds Excessive uterine activity with an atypical or abnormal fetal heart rate

Oxytocin should not be continued or rate increased in the presence ofat ical or abnormal fetal heart rate and/or tetanic contractions

Intrauterine Resuscitation Measures

Stop oxytocin infusion Reposition to left lateral decibitus

Continue or initiate EFM

Give oxygen mask at 10 L/min Notify responsible physician Administer a tocolytic agent Prepare for possible cesarean delivery if fetal pattern remains abnormal


19/51

MEMBRANE SWEEPING / STRIPPING

o Sweeping of the membranes, also named stripping of the membranes, is a relativelysimple technique usually performed without admission to hospital. During vaginalexamination, the clinician's finger is introduced into the cervical os. Then, the inferior

pole of the membranes is detached from the lower uterine segment by a circularmovement of the examining finger. This intervention has the potential to initiate labor by

increasing local production of prostaglandins and, thus, reduce pregnancy duration orpre-empt formal induction of labor with either oxytocin or amniotomy.

o Sweeping the membranes during a cervical examination is done to bring in labor womenat term.

o The review of trials found that sweeping brings on labor and is generally safe where thereare no other complications. Sweeping reduces the need for other methods of labor

induction such as oxytocin. The review also found that sweeping can cause discomfortduring the procedure, some bleeding and irregular contractions.

o Before formal induction of labor, women should be offered sweeping of the

membranes19

, and when this is proposed, discussion between the physician and thepatient should include information that membrane sweeping is not associated withincrease in maternal or neonatal infection, and that it may be associated with increased

levels of discomfort and bleeding during the procedure (RCOG, Grade A).

o At the 40th

and 41stweek of antenatal visit of nulliparous women, and at the 41

stweek

antenatal visit of parous women, patient should be offered a vaginal examination formembrane sweeping.

19

o When a vaginal examination is carried out to assess the cervix, the opportunity should betaken to offer the woman a membrane sweep. Additional sweeping may be offered if

labor does not occur spontaneously.19

AMNIOTOMY (see also Chapter in Amniotomy)

o Artificial rupture of the membranes may be used as a method of labor induction,especially if the condition of the cervix is favorable.

o Used alone for inducing labor, amniotomy can be associated with unpredictable andsometimes long intervals before the onset of contractions.

FAILED INDUCTION: DEFINITION

A failed induction of labor may be diagnosed in women whose continued lack ofprogression into the active phase makes it unlikely that they would safely proceed to a vaginaldelivery. A group suggested that nulliparous women could safely remain in the latent phase for

up to 12 hours, whereas women who remained in the latent phase for longer periods had a lowchance (13%) of subsequent vaginal delivery. It is not unreasonable to allow up to 18 hours of

latent labor before recommending a cesarean for a failed induction.20

C. INTRAPARTUM NUTRITION

o The management of oral intake of parturients seeks to provide adequate hydration andnutrition while maintaining safety for the mother and baby.

o Many obstetricians restrict oral food and fluid intake during active labor because of the

possible risk of aspirating gastric contents with the administration of anesthesia.However, sources of energy need to be replenished during labor in order to ensure fetaland maternal well-being.

o The incidence of aspiration of gastric contents has always been low and therefore plays avery small role as a cause of maternal death.

11

Recommendations:

o For the normal, low-risk birth in any setting, there is no need for restriction of food,except in situations where intervention is anticipated. (Level II-2, Grade B). Hence the

health status of the woman and the risk of surgical intervention should always beadequately assessed.

o The Cochrane Pregnancy and Childbirth Group recommends a diet of easy-to-digestfoods and fluids during labor for women who wish to eat and drink.

o Isotonic calorific drinks consumed during labor reduce the incidence of maternal ketosiswithout increasing gastric volumes (Level II; Level III-3).

o Routine intravenous infusions interfere with the natural birthing process and restrictwomens freedom to move. Even the prophylactic routine insertion of an intravenous line

can be considered unnecessary intervention.o Intravenous infusion to treat or prevent dehydration, ketosis or electrolyte imbalance is

not as effective as allowing food and fluids in labor.

o The use of epidural anesthesia for intrapartum pain management in an otherwise normallabor should not preclude oral intake.

o The correct approach for normal childbirth should include an assessment of the risk ofgeneral anesthesia.

D. ENEMA DURING LABOR

o Enemas are thought to decrease the risk of puerperal and neonatal infections, shorten theduration of labor and make delivery cleaner for attending personnel.

o However, enemas are upsetting and humiliating for women in labor and may causeincreased pain.

o Enemas also cause watery stools and could theoretically increase contamination andinfection rates.

Recommendation:

o There is no evidence to support the routine use of enemas during labor. Although theseresults cannot rule out a small clinical effect, it seems unlikely that enemas will improvematernal and neonatal outcomes and provide an overall benefit. (Level 1, Grade A)

E. MONITORING THE PROGRESS OF LABOR

o For monitoring the progress of labor, one may use the Friedmans labor curve (Figure 1),

or the WHO partogram (Figure 2). (Level 2, Grade B)

Figure 1: Friedmans Curve

The labor curve is plotted as a function of cervical dilatation (cm) and fetal descent

(stations) versus time (usually in hours from onset of regular uterine contractions). The rate of

change of these two parameters is the measure of the efficiency of the labor process. The end of

labor takes place when there is expulsion of the fetus and the placenta.

There are 2 major events in Labor. (Figure 1, Friedmans Curve)

1. Cervical effacement and dilation (straight lines below)

2. Fetal descent through the birth canal

The Friedmans Curve(Dilatational and Descent)


24/51

Cervical Effacement and Dilatation

DILATATION CURVE

1. Latent phase; up to 3-4 cm dilatation (approximately 8 hrs long)

2. Active Phasea. Acceleration phase not always present

b. Phase of Maximum Slope (PMS)- occurs at approximately 9 cm. dilatation

- fetus is considered fully descended as it falls one station below the ischial spine (+1)c. Deceleration always present

Latent phase

Latent phase ends at 3-4 cm dilatation (approximately 8 hrs long) Extends from the onset of labor, timed from the onset of the regular uterine contractions,

to the beginning of the active phase. The duration of the latent phase is more variable and is sensitive to influences of

extraneous factors, sedation and myometrial stimulation.

Its duration does not have major influence over the subsequent course of labor.

Active Phase The point in time when the rate of dilatation begins to change acutely, the curve

becoming more steeply inclined. This phase ends at full cervical dilatation when the cervix is no longer palpable. The active phase maybe further subdivided into three distinctive phases:

a. Acceleration phase- This phase may not always be detected. In contrast to the latent phase, the

steepness of this part of the curve is reflective of labor outcome.b. Phase of Maximum Slope (PMS)

- Since this is the time when cervical dilatation proceeds at its most rapid rate , thisphase of cervical dilatation is reflective of the overall efficiency of the contractile

machine (uterus).c. Deceleration Phase

- This phase shows the feto-pelvic relationship and heralds entry into the pelvicdivision of labor. This is the time wherein the classic cardinal movements of labor

take place.

Functional Divisions of Labor

1. Preparatory Division latent phaseEncompasses the latent and acceleration phase of cervical dilatation. At this time littlecervical dilatation takes place.


25/51

2. Dilatational divisions active phase(when CERVICAL DILATATION occurs)

Encompasses the phase of maximum slope of the cervical dilatation. When the rate ofdilatation is fastest.

3. Pelvic Division concerned mostly with the descent aspect of deliveryCommences with the deceleration phase and second stage of labor. This is where theclassical cardinal movements of labor primarily occurs. The demarcation between this

and the dilatational division is clinically difficult to determine

Fetal Descent

o also shown in Friedmans curve

1. Latent phase no fetal descent occurs- extends beyond dilatational phase of descent curve

2. Active Phase comes much latera. Accelerationb. Phase of maximum descent

- occurs at around 9 cm dilatation

- corresponds to the deceleration of dilatation

- fetus fully descended at +1 (station at the level of ischial spines)

o The pattern of descent follows a hyperbolic curve (station vs duration of labor). Likecervical dilatation, it too has its phases as follows:

1. The Latent Phase of fetal head descent corresponds to the latent and accelerationphase of cervical dilatation (the preparatory division of labor). At this time, littleif at all, fetal head descent takes place.

2. The Acceleration Phase of descent corresponds to the phase of maximum slope(the dilatational division of labor) of cervical dilatation. This is the time that fetalhead descent ensues.

3. The Phase of Maximum Slope of descent encompasses the deceleration phase and

second stage of labor in cervical dilatation (pelvic division of labor). Especially innulliparas, increased rates of descent begins during this phase and progresses to a

maximum until the presenting part reaches the perineal floor. As this eventoccurs, the cervix is expected to be at an advanced stage of dilatation (8-9 cm).

o In a vertex presentation, engagement occurs when the biparietal diameter has reached orpassed the pelvic inlet.

o Often, the leading edge is at or below the plane of the ischial spines.o Station refers to the level of the leading edge of the presenting part in relation to the

interspinous plane.


26/51

o The level at which the biparietal diameter is at however, is not indicated by station.o Station 0 is said to be reached when the lowermost part of the fetal head has reached the

ischial spines and has just engaged.

o Fetal head engagement usually occurs before labor in nulliparas.o Its progress however occurs only late in labor. In multiparas, this event often occurs

during labor.

WHO PARTOGRAPH

o If graph is located on the right side of the ALERT LINE: one should monitor the patientclosely.

o If graph reaches the ACTION LINE: should do cesarean section or forceps/vacuum

delivery.

The principles of the partograph include the following:

1. The active phase of labor commences at 3 cm dilatation.2. The latent phase of labor should last no longer than 8 hours.3. During the active phase, the rate of cervical dilatation should not be slower than 1

cm/hour.

4. A lag time of 4 hours between a slowing of labor and the need for intervention isunlikely to compromise the fetus or mother and avoids unnecessary intervention.

5. Vaginal examinations should be performed as infrequently as is compatible with safepractice (once every 4 hours is recommended).

o The partograph is intended for use in all maternity settings, but has a different level offunction depending on the level of health care provision.

o In a health center, the critical function is to give early warning that labor is likely to beprolonged and transfer to hospital is mandated (alert line).

o In hospital, the right of the alert line is a warning for extra vigilance, but the action line isthe critical point which signals the need for specific interventional decisions. (Level 2b).

Parameters to record in the partograph

A. Patient information:Fill out name, gravida, para, hospital number, date and time of admission and time of

ruptured membranes.

A. Fetal heart rate:Record every half hour.

B. Amniotic fluid:Record the color of amniotic fluid at every vaginal examination. The following codes areused:

dilatation at the rate of 1 cm per hour.

Action line: Parallel and 4 hours to the right of the alert line.

E. Descent assessed by abdominal palpation:Refers to the part of the head (divided into 5 parts) palpable above the symphysis pubis;recorded as a circle (O) at every vaginal examination. At 0/5, the sinciput (S) is at the

F. MATERNAL POSITION DURING THE FIRST STAGE OF LABOR

o There is evidence that walking and upright positions in the first stage of labor reduce thelength of labor and do not seem associated with increased intervention or negative effects

on mothers and babies well-being. Women should be encouraged to take up whateverposition they find most comfortable in the first stage of labor.

G. ANALGESIA AND ANESTHESIA DURING LABOR

o The most ideal labor analgesia technique should adequately reduce pain of the first and

second stage of labor.! Preferably, it should not interfere with the progress of labor.! And most importantly it should be devoid of unwanted side effects on the mother,

allowing her to participate readily in the birthing process and should have no or

very minimal effect on the baby.

o Systemic opioids like meperidine are the most common medications used for labor painrelief.


31/51

! Usually they are given intramuscularly and combined with a phenothiazine todecrease the side effect of nausea and vomiting.

! Use of these drugs do not require the use of specialized equipment or personnel.! They allow the parturient to better tolerate the pain of labor, but characteristically

do not provide adequate analgesia especially for the second stage of labor.! More so, they cause a dose-dependent increase in unwanted side effects likedrowsiness, nausea and vomiting for the mother .! And because these drugs easily cross the placenta, they are associated with risks

of respiratory depression and neurobehavioral changes in the newborn.

o Of all the methods of labor pain relief available in clinical practice, neuraxial analgesia(epidural and spinal) are most effective methods of intrapartum pain relief.

! Administration of epidural analgesia traditionally involves an injection of localanesthetic through a catheter positioned in the epidural space.

! Epidural solutions are administered either by bolus or infusion, or patientcontrolled analgesia which permits analgesia to be maintained throughout labor.

! This technique offers the highest patient satisfaction and the least depressanteffects on the newborn compared with parenteral opioids.

o When neuraxial catheter techniques are used for analgesia during labor or vaginaldelivery, the primary goal is to provide adequate maternal analgesia with minimalmotor block which is achieved with the administration of local anesthetics at low

concentrations with or without opioids.! Controversy exists though, with regards to its effect on the duration of first and

second stage labor, use of instrumental delivery, and the time of administration ofthe epidural among others.

! Many care providers are concerned that epidural analgesia increases the risk ofcaesarean section.

o Epidural analgesia should not be taken as a single entity. There are many variations of theepidural which can be tailored to the patients obstetric needs.

! One of the more common variations is the combined spinal epidural analgesia(CSE) which combine the advantages of both the spinal epidural techniquesincluding: faster onset, due to the spinal component and subsequent labor

analgesia via the epidural catheter.

o The other techniques for labor pain relief like the pudendal block, nitrous oxidesubanesthetic concentrations of inhalational gases provide less superior analgesia

compared with neuraxial blocks.

Recommendations:

o During labor, a parturients request for pain relief is a sufficient indication for its use.When available and after sufficiently explaining the possible options for labor with their


32/51

corresponding advantages and disadvantages, all laboring mothers should be given theoption to choose which form of labor analgesia they prefer.

o Although meperidine is the most common parenteral opioid used, other opioids(nalbuphine, butorphanol) are as comparable to meperidine and may be given

parenterally. (Level 1, Grade A)

o Note though that these systemic medications do not provide adequate pain reliefespecially for the second stage of labor. Care should be taken in giving high doses as theymay cause side-effects of pruritus, nausea, vomiting, and drowsiness in the mother and

respiratory depression necessitating aggressive resuscitation in the newborn.

o When not contraindicated (e.g. hypovolemia, coagulopathy), neuraxial analgesia (spinalor epidural) using local anesthetic with or without neuraxial opioids provides the most

effective pain relief for labor. (Level 1, Grade A).

o

These techniques should be administered by a trained and skilled anesthesiologist in anappropriate medical facility with appropriate resources for the treatment of complications(e.g., hypotension, systemic toxicity, high spinal anesthesia) should be available.

! If a neuraxial opioid is added, treatments for related complications (e.g., pruritus,nausea, respiratory depression) should be available.

o The following varieties of neuraxial analgesia provide satisfactory analgesia for labor anddelivery and may be used according to patients and providers preference and availabilityof resources: (Level 1, Grade A)

a. Epidural analgesia using intermittent boluses or continuous infusionb. Combined spinalepidural (CSE) may be used to provide rapid and effective

onset of analgesia for labor.

c. Patient-controlled epidural analgesia (PCEA) may be used to provide an effectiveand flexible approach for the maintenance of labor analgesia.

o Single shot spinal-injection spinal opioids with or without local anesthetics may be usedto provide a less expensive but effective, although time-limited, analgesia for labor when

spontaneous vaginal delivery is anticipated.

o Patients in early labor (i.e. 2 cm dilation) should be given the option of neuraxial

analgesia when this service is available. Neuraxial analgesia should not bewithheld on the basis of achieving anarbitrary cervical dilation, and shouldbe offered on an individualized basis.

* Patients may be reassured that the use of neuraxial analgesia does notincrease the incidence of cesarean delivery. (Level 1)


33/51

o Patients and care providers should be informed that epidural analgesia may increase theneed for labor augmentation (use of oxytocin), need for instrumental delivery, and slight

prolongation of second stage labor. (Level 1, Grade A)

o For imminent delivery the following may be used:

a. Pudendal block may offer analgesia for episiorraphy and repair if needed (LevelIII, Grade C)b. Single shot spinal (saddle block) (Level III, Grade C)

c. Intravenous thiopental, propofol, or ketamine may be administered parenterallyby a skilled anesthesiologist (Level III, Grade C)

o The use of low concentrations of volatile anesthesia for labor analgesia, is no longeraccepted as a standard of care for labor and vaginal delivery. General anesthesia obtundsthe patients airways reflexes and increases the risk for airway aspiration and its

subsequent sequelae. (Level III, Grade C)

H. AMNIOTOMY

Definition:

o Amniotomy is the artificial rupture of membranes.

Artificial rupture of the amniotic membranes during labor is one of the most commonlyperformed procedures in modern obstetrics.

Recommendations:

Timing

There is still no conclusive evidence to support that early amniotomy has a clear advantageover expectant management (Level 1, Grade C).

Supporting Statements:

o Early amniotomy appears to lead to an average reduction of labor.o Routine amniotomy doesnt significantly reduce the duration of first-stage labor in either

primiparous or multiparous women (Grade A).

o It slightly shortens second-stage labor in primiparous women only (Grade A).

Use

o The primary aim of amniotomy is to speed up contractions and shorten the length of

labor.o Amniotomy may also be used to assess the status of the fetus.o Amniotomy is employed with the assumption that shortening the length of labor is

beneficial, with little apparent regard for any potential associated adverse effects.o Many caregivers promote amniotomy on the clinical assumption that it increases labor

contractions and therefore improves labor progress4 especially in those women with

prolonged labor.5

o To observe the colour and amount of amniotic fluid as clinically indicated.

Complications

o With regard to labor dystocia, ACOG states that amniotomy may enhance progress inthe active phase and negate the need for oxytocin augmentation, but it may increase therisk of chorioamnionitis.

o Possible complications include umbilical cord prolapse, cord compression and fetal heartrate decelerations, increased ascending infection rate, bleeding from fetal or placental

vessels and discomfort of the actual procedure.6

I. CONTINUOUS SUPPORT DURING LABOR

Recommendations:

o There is sufficient evidence that women who receive continuous one-on-one supportduring labor are more likely to deliver without analgesia or anesthesia, will have a

slightly shorter duration of labor and are more likely to deliver spontaneously. They arealso less likely to be dissatisfied with their childbirth experience. (Level I)

o The person providing labor support may be a trained caregiver, not an employee of theinstitution, and is physically present to provide this care. She/He should be present early

in labor and remain all throughout until delivery and help initiate breastfeedingimmediately postpartum.

o Most beneficial in institutions that do not allow laboring women to bring companions oftheir choice, or where epidural anesthesia is not available or where continuous electronic

fetal monitoring is not routine

Elements of Support:! emotional support (continuous presence, reassurance and praise)! physical measures of comfort (massages, comforting touches, acupressure, etc)

advocacy like helping the woman to express her wishes and needs to others

Continuous support by a lay woman during labor and delivery:

! facilitates birth! enhances the mothers memory of the experience! strengthens mother-infant bonding; increases breastfeeding success! significantly reduces many forms of medical intervention, including cesarean

delivery, the use of analgesia, anesthesia, and vacuum extraction.

Duration of Support:! Continuous (without interruption except for toileting)! Intermittent


37/51

Types of Provider:! Untrained lay women! Trained lay women (doulas)! Female relatives! Nurses!

Monitrices (lay midwives acting solely as labor support persons)

Outcomes assessed:

! Use of any analgesia! Need for oxytocin augmentation! Need for forceps or vacuum! Need for Cesarean Section! Duration of labor

Those who received continuous labor support:! 26% less likely to give birth by cesarean section!

41% less likely to give birth with vacuum extraction or foceps! 28% less likely to use any pain medications and! 33% less likely to be dissatisfied with or negatively rate their birth experience

Benefits of continuous labor support appear to be greater when women receive it:! beginning earlier rather than later in labor! in settings that do not allow them to bring! companions of choice (versus settings that do! allow husbands, friends, etc.)! in settings where epidural analgesia is not routine

III. SECOND STAGE OF LABOR

A. ROUTINE PERINEAL SHAVING BEFORE DELIVERY

o

There is insufficient evidence to recommend routine perineal shaving for women onadmission in labor. (Level I, Grade E)

Late side effects attributable to shaving occur later such as:1. Irritation2. Redness3. Multiple superficial scratches from the razor4. Burning and itching of the vulva.

o No trial assessed the views of the woman about shaving such as:

1. Pain

2. Embarassment3. Discomfort during hair regrowth

SUPPORTING STATEMENTS Shaving the pubic hair of women in labour is done routinely before birth as a hygienic

practice in some settings. This practice should be evaluated to see whether it really has value or not. In some settings, women in labor are routinely shaved upon admission to hospital The aim is to minimize infection risk if there is tearing or cutting of the area between the

vagina and anus (which is common) during the birth process.

It also has been suggested that a shaved area may make stitching tears or cuts easier.

Reference

B. MATERNAL POSITION DURING THE SECOND STAGE OF LABOR

Recommendations:

o The upright position in the second stage of labor is associated in women withoutepidural anesthesia with a 4-minute shorter interval to delivery, less pain, lower

incidences of nonreassuring fetal heart rate monitoring and of operative vaginal delivery,as well as higher rates blood loss of > 500 ml compared with other positions in 20 trials

including 6135 women.


40/51

o The upright positions studied include sitting (obstetric chair/stool); semi-recumbent(trunk tilted backwards 30 to the vertical); kneeling; squatting (unaided or using

squatting bars); and squatting aided with birth cushion.

o The benefits of the upright position may be related to gravity, less aortovagalcompression, improved fetal alignment, and larger anterior- posterior and transverse

pelvic outlets. The higher blood loss may be secondary to easier collection of blood in theupright position.

o In women with mostly epidural anesthesia, 1 small trial assessed lateral vs supportedsitting position, without enough power for meaningful conclusion

o Another trial compared 2 upright positions, and associated kneeling with no difference induration of second stage but less pain compared with sitting (recommendation: A;quality: good US preventive services task force).

C. ALTERNATIVE METHODS OF BEARING DOWN

o There is no evidence that the rate of adverse perineal outcomes is affected by differenttypes of bearing down during the second stage of labor (Level 1, Grade C). A systematic

review of controlled trials has found no evidence of a difference holding (Valsalva) orspontaneous exhalatory methods of pushing are used during the second stage of labor.

D. PERINEAL SUPPORT: HANDS POISED VERSUS HANDS ON

Definition:

o Hands On = touch the perineumo Hands poised / Hands off = do not touch the perineum

Recommendations:

o Hands Off and Hands On techniques did not affect the frequency or severity ofperineal trauma in women undergoing childbirth for the first time.1 (Level I, Grade C)

o Perineal trauma is associated with other factors1:

1. Position during delivery2. Use of oxytocin

3. Maternal expulsive efforts

4. Presence of a support person

SUPPORTING STATEMENTS

The hands poised method increased short term perineal pain and increased the risk of

manual removal of the placenta, however it found no evidence of an effect on the risk ofperineal trauma or third/fourth degree tears.

E. INSTRUMENTAL VAGINAL DELIVERY

o An analysis of maternal and fetal outcomes in assisted vaginal deliveries does notindicate that vacuum extraction is superior to forceps or vice versa. Each instrument

appears to have its own advantages and disadvantages. The greater frequency of maternalperineal trauma with forceps deliveries evens out with the increased occurrence of fetal

injuries with vacuum extractions. It is therefore recommended that only practitioners whoare adequately trained or are well-supervised should perform the instrumental delivery of

their choice. The mode of intervention (forceps or vacuum) should be individualized after


42/51

consideration of the operators skills and experience, and the clinical situation. (Level 1,Grade A)

Vaginal Delivery

Recommendations:

o Indications for operative vaginal delivery are never not absolute.o When the fetal head is engaged and the cervix fully dilated, the following indications

apply.1. Prolonged second stage

o Nulliparous women: lack of continuing progress> 3 hours with regional anesthesia

> 2 hours without regional anesthesia.

o Multiparous women: lack of continuing progress

> 2 hours

with regional anesthesia> 1 hour without regional anesthesia.

2. Suspicion of immediate or potential fetal compromise3. Shortening of the second stage for maternal benefit.

Forceps Delivery

o Elective forceps delivery should be done only when the criteria for outlet forceps havebeen met.

o Criteria for types of forceps delivery have been defined by ACOG as follows. (The

definition of types of forceps deliveries have been refined to avoid the inclusion of eithertrivial or extremely difficult deliveries under the category of midforceps).

CriteriaOutlet forceps

Scalp is visible at introitus without separating the labia Fetal skull has reached pelvic floor Sagittal suture is in anteroposterior diameter or ROA/LOA or ROP/LOP Fetal head is at or on perineum Rotation does not exceed 45 degrees

Low forceps Leading point of fetal skull is at station =/> 2 cm and not on the pelvic floor Rotation is 45 or less (LOA/ROA to OA, or LOP/ROP to OP) Rotation is greater than 45

Midforceps

Station is above +2 cm but head is engaged (to include caput formation?)


43/51

High forcepso Not included in classification

* Mid/High forceps are not currently recommended.

Recommendations:

o If a satisfactory application of the forceps cannot be achieved, then the procedure isabandoned and delivery accomplished by use of either vacuum extraction or cesarean

section.o If application has been achieved but gentle downward pulls do not result in descent, the

procedure is abandoned.

o In some situations, vacuum extraction may be successful, otherwise cesarean delivery isperformed.

11

Vacuum Delivery

Recommendations:

o There is inadequate evidence upon which to base a recommendation for use of aparticular type of vacuum for all circumstances when a vacuum assisted delivery isattempted.

o A successful vacuum extraction is most likely if there is:- accurate cup application at the flexion point

- appropriate traction technique- a favorable flexed fetal cranial position

- low station at the time of application

o Only attempt a vacuum assisted delivery when a specific obstetric indication is present.As in forceps, no indication is absolute.

o The use of soft, bell-shaped vacuum extractor is recommended for uncomplicated, OAdeliveries

o Limit vacuum assisted procedures to 2 to 3 "pop-offs," and a total time of 15 to 30minutes.

o Failure of an attempted vacuum assisted delivery increases the likelihood of neonatalmorbidity; the subsequent use of sequential forceps in this setting should be undertakenwith extreme caution.

o Prompt cesarean delivery is advised after an unsuccessful vacuum assisted procedure.

In the U.S., the percentage of births delivered by forceps or vacuum extractionreported in 1997 increased slightly from 9.0% to 9.4%.4 In the Philippines,

forceps delivery range from 1.7% to 6.8%.5

The Philippine Board of Obstetricsand Gynecology (PBOG) requires trainees to complete at least 15 forceps and/or

vacuum deliveries by the end of the 2ndyear of the four-year training period.6

IV. THIRD STAGE OF LABOR

A. USE OF EPISIOTOMY AND REPAIR

Recommendations:

o Restricted use of episiotomy preferable to routine use (Level I, Grade A)o Median episiotomy is associated with higher rates of injury to the anal sphincter and

rectum (Level I, Grade A)

o Mediolateral episiotomy may be preferable to median episiotomy in selected cases (LevelI, Grade B)

o Routine episiotomy does not prevent pelvic floor damage leading to incontinence (LevelI, Grade B)

Repair

o In either median or mediolateral episiotomy, 2-layered closure can improve postpartumpain and healing complications vs a 3-layered closure.

o Polyglycolic acid derivative suture, with minimal reaction, is recommended to reducewound inflammation. (Level I, GradeA)

Episiotomy

Purpose:facilitate second stage of labor to improve maternal and neonatal outcome

Maternal benefitReduced risk of perineal trauma, subsequent pelvic floor dysfunction and prolapse,

urinary incontinence, fecal incontinence and sexual dysfunction Fetal benefit

Shortened second stage of labor

Indications:

Expedite delivery in the second stage of labor When spontaneous laceration is likely Maternal or fetal distress Breech position Assisted forceps delivery Large baby Maternal exhaustion


46/51

Routine vs. Restrictive Episiotomy

Routineo Routinely conducted, usual careo Use to pre-empt a tear

Restrictiveo Avoid episiotomy unless indicated for fetal well-being or to avoid laceration

Reference

ACOG Practice Guidelines April 2006

B. SUTURE MATERIALS FOR EPISIORRAPHY

o There is good evidence to support the use of fast-absorption polyglactin 910 as materialof choice for perineal closure. (Level I, Grade A)

Fast-absorbing Polyglactin 910

- Obviates need for suture removal up to 3 months postpartum for 1 in 10 womensutured1

- Less dyspareunia at 6 weeks2- Similar wound breakdown profile as chromic rarely requires late removal3- Earlier resumption of sexual intercourse4

Recommendations:

RCOG Guideline No. 23

o Rapid-absorption polyglactin is the most appropriate suture material for perineal repair.o Catgut suture material has been withdrawn from the UK since 2002.

Technique

o Continuous suturing techniques form perineal closure compared to interrupted methods,are associated with less pain. Moreover, if the continuous technique is used for all layers(vagina, perineal muscles and skin) compared to perineal skin only, the reduction in pain

is even greater.5

o Less short term pain with continuous technique.6

C. MANAGEMENT OF THIRD STAGE OF LABOR

Recommendations:

o Active management includes a group of interventions such as1. administration of prophylactic uterotonin within one minute after the delivery of the

baby and prior to the delivery of the placenta

2. early cord clamping and cutting3. controlled cord traction to deliver the placenta

Physiologic bases of the steps in the active Management of 3rd

stage of labor to prevent

Postpartum Hemorrhage (PPH):

The 3 interventions hasten placental delivery by increasing uterine contractions, thusdecreasing blood loss and preventing PPH by averting uterine atony.

Giving uterotonics " increased uterine contractions/retraction" total detachment andexpulsion of the placenta "optimal occlusion of the myometrial vessels" preventing

PPH.

Early clamping and controlled cord traction = shorter duration of the 3rdstage, lowermaternal blood loss, lower incidence of retained placenta.

Early clamping decreases mother-to-baby transfusion. Giving uterotonics withoutearly clamping accelerates this transfusion and may disturb the physiological

equilibrium of the blood volume within the feto-maternal unit and creating a varietyof undesirable effects in the neonate.

The use of combination preparation (oxytocin and ergometrine) as part of the routineactive management of the third stage of labor appears to be associated with a

statistically significant reduction in the risk of PPH when compared to oxytocin alone

where blood loss is less than 1000 ml. (Level I, Grade B) Administration of oxytocin alone is as effective as the use of oxytocin plus

ergometrine in the prevention of PPH, but is associated with a significantly lower rate

of unpleasant maternal side effects (nausea, vomiting and hypertension). (Level II,Grade B)


48/51

Recommended Doses :1. Oxytocin 10 u/500 ml NSS (20u/1000 ml NSS) - continous IV drip OR

5 u IV bolus2. Ergometrine 200-250 mcg IM OR 100-125 mcg IV bolus

D. DRUGS IN THE THIRD STAGE OF LABOR

Recommendations:

o Oxytocin is effective as 1st line prophylactic uterotonic during the 3rd stage of labor inthe prevention of PPH and is safe to use on all patients. (Level I)

o Use of ergot alkaloid and ergometrine-oxytocin are valid alternatives in the absence ofoxytocin. Their use have to be weighed against maternal adverse effects. (Level I)

o Use of ergot alkaloid and ergometrine-oxytocin combination have to be avoided in

hypertensive patients. (Level I)o In low resource area, and in the absence of other uterotonics, Misoprostol, if legally

available, is a valid alternative and may be administered orally, sublingually or rectally.

(Level I)

Uterotonic Drugs

Oxytocin Ergot alkaloid Ergometrine oxytocin

Prostaglandin

3 components: Uterotonics using oxytocin by IM within 1 min after delivery of baby Early clamping and cutting of the cord Controlled cord traction

V. FOURTH STAGE OF LABOR

EARLY BREASTFEEDING

o The American Academy of Physicians, American College of Obstetricians andGynecologists, American Academy of Family Physicians, Academy of Breastfeeding

Medicine, World Health Organization, United Nations Childrens Fund, and many otherhealth organizations recommend exclusive breastfeeding for the first 6 months of life.

Education Minimize maternal medications intrapartum Avoid traumatic procedures on infant Direct skin to skin contact right after delivery Rooming-in Frequency of feedings

o Breastfeeding should be continued for at least the first year of life and beyond for as long

as mutually desired by mother and child.o Certain conditions enumerated below may preclude or make difficult direct breastfeeding

or latch-on right after birth. When these are present, expressed human milk collected by

manual expression or pumping is advised. These maneuvers may help maintain milkproduction.

1. Maternal anatomic abnormalities of the breast

2. Neonatal anatomic abnormalities

3. Neonatal depression

o Breastfeeding is contraindicated in mothers with the following conditions:

Use of street drugs/alcohol

Infant with galactosemia Maternal infection (HIV, active PTB, varicella, herpes simplex)

Use of neoplastic, thyroid, immunosuppressants

Undergoing treatment for breast cancer
