11
Induced Vaginal Delivery: Pitocin
• Most commonly used drug in the US –synthetic form of oxytocin
• Physiology of oxytocin-stimulated labor is similar to spontaneous labor– Stimulates an increase in intracellular calcium
in uterine myometriumin uterine myometrium
– Causes contractions of the uterus. Used to:• Start labor
• Increase the speed of labor
• Stop bleeding following delivery 12

17
Emergency C-Section
• Coordination of at least six individuals:• Coordination of at least six individuals: surgeon, assistant for the surgeon, anesthesiologist, scrub technologist, circulating nurse and pediatrician

Pain Control During Labor and Delivery
• Available methods of analgesia• Available methods of analgesia– Parenteral
– Regional• Epidural
• Spinal
21
Pain Control: Parenteral• Can be given in intermittent doses by
ti t tpatient request
• Don’t relieve pain, but reduce anxiety and result in sedation
• May be set up via patient-controlled administration (PCA) pain pumps
Agent Usual Dose Frequency Onset
Meperidine 25-50mg IV Q 1-2 hours 5 minutes
Fentanyl 50-100 mcg IV Q 1 hour 1 minute
Butorphanol 1-2mg IV Q 4 hours 1-2 minutes
Morphine 2-5mg IV Q 4 hours 5 minutes
Nalbuphine 10mg IV Q 3 hours 2-3 minutes

Sterile Drug Products Used During Delivery and the Postpartum PeriodPharMEDium Lunch and Learn Series
ProCE, Inc.www.ProCE.com 12
Pain Control: Regional
• Partial to complete loss of painp p
sensation below T8 to T10
• Epidural – offers the most effective form of pain relief – Catheter is placed in the epidural space; continuous
infusion of local anesthetic agents or narcotics
– Can be used for c-section delivery or postpartum tubal ligation
– Commonly combine a low-dose local anesthetic (e.g., bupivacaine, or ropivacaine) with an opioid agonist (fentanyl)
23
Pain Control: Regional
• Spinal block – single-shot spinal analgesia p g p g– Excellent pain relief for short duration procedures
• C-section delivery
• Second stage of labor
• Rapidly progressing labor
• Postpartum tubal ligation p g
– Long-acting local anesthetic often used, with or without opioid agonist
– Duration approximately 30-250 minutes depending on agent(s) used

Current Recommendations
• Most practitioners will use LMWH until week 36
• Switch the heparin in preparation for delivery– Shorter half-life
L i k f id l i l h i h– Lower risk of epidural or spinal hematoma with regional anesthesia
• Typically withhold neuraxial blockade for 10-12 hours after last prophylactic dose of LMWH or 24 hours after last therapeutic dose of LMWH

Hyperemesis Gravidarum: Treatment
• Methylprednisolone 16mg TID x 3 days followed• Methylprednisolone 16mg TID x 3 days, followed by a 2 week taper with oral promethazine– One RTC found steroids reduce the rates of hospital
readmission within 2 weeks1
– Another found steroids have no effect on need for rehospitalization2
