Case

5 week old male infant with chief complaint of vomiting ◦ Has had almost daily emesis since birth ◦ Usually dribbles out of mouth ◦ Now more forceful and occurring with every feed ◦ No respiratory symptoms

◦ Now appears weak, eyes sunken

Radiology

Case Discussion: Hypertrophic Pyloric Stenosis (HPS) (1 of 2)

Background HPS: The most common surgical cause

of vomiting in infants. Hypertrophy of the circular musculature

surrounding the pylorus leads to obstruction of the gastric outlet.

Case Discussion: Hypertrophic Pyloric Stenosis (HPS) (2 of 2)

Background Infants with HPS present with nonbilious

projectile vomiting in the second to fourth weeks of life. Symptoms rarely occur before 2 weeks or

later than 4 to 6 months of age.

Your First Clue: HPS

• Male infant • Nonbilious, projectile emesis • Hungry appearing • Visible peristaltic waves • Palpable olive-shaped pylorus in

midepigastric region

Peristaltic Wave

Peristaltic Wave

Radiology Until recently, upper GI was the

"gold standard" for diagnosis of pyloric stenosis.

Positive upper GI signs for HPS are “string sign" (single streak of barium in lumen of elongated pylorus).

Ultrasonography

Indicative of pyloric stenosis

Length ≥ 1.6 cm wall thickness ≥ 0.4 cm Diameter ≥ 1.4 cm are

Management

ABCs Naso- or orogastric tube decompression Correct dehydration, metabolic and electrolyte

abnormalities with intravenous fluids. Ensure adequate urine output. Consult a pediatric surgeon. Surgery delayed until electrolytes stable

Case Progression/Outcome

Electrolytes: hypochloremic, hypokalemic, metabolic

alkalosis. Fluid resuscitation and gastric decompression

were initiated. A pediatric surgeon was consulted. Patient underwent a pyloromyotomy 2 days after

admission and was discharged 3 days later.

Case

18-month old infant ◦ Vomiting x 1 day, multiple times, nondescript ◦ Abdominal pain, nondescript, appears intermittent ◦ Lethargy afterwards ◦ Draws legs up into abdomen with discomfort

Radiology

Discussion: Intussusception

Intussusception is an invagination of the proximal portion of the bowel into an adjacent distal bowel segment.

Second most common cause of intestinal

obstruction in infants Approximately 80% to 90% involve

invagination of the ileum into colon (ileo-colic).

Background (1 of 2)

Peak age of occurrence is between 5 and 9 months, with most cases occurring from 3 months to 2 years.

10% to 25% occur in children older than 2

years.

Your First Clue: Intussusception (1 of 2)

Classic triad Intermittent colicky abdominal pain

(85%-90%) Vomiting (65%-80%) Emesis may be nonbilious, but may

become bilious or feculent. Bloody Stool with mucoid "currant jelly" stools---late finding

Your First Clue: Intussusception (2 of 2)

Only 20% have all three 70% have two of three

Radiology: Meniscus or Crescent Sign

Ultrasonography

Radiology: Barium or Air Contrast Enema

Management

ABCs Fluid resuscitation

Obtain surgical consultation. Perform barium or air contrast enema. Surgical reduction for: Signs of peritonitis Shock Pathologic lead point Unable to reduce with barium or air contrast enema

Case Progression/Outcome

After fluid resuscitation, Air contrast enema. Intussusception was

found and reduced. Lethargy quickly disappeared, and the

infant took oral fluids. The infant was discharged after

observation in ED.

Intussusception

Risk of recurrence Typically in the first 24 hours. Enema reduction 5-10% Surgical reduction 1-4%

Disposition Data shows safety with discharge from ED

Midgut Volvulus

Malrotation with Midgut Volvulus

Usually presents in first year of life 75% < 1 mo; 90% <1yo Rarely may not present until childhood

Abdominal pain - nonspecific Bilious vomiting Abdominal distension and hematochezia

may be present Mortality up to 60%

Malrotation with Midgut Volvulus - Radiography

Shigella Salmonella E. coli Campylobacter Yersinia Vibrio cholera

Viral: 60%

Rotavirus Norwalk and Norwalk-

like (calicivirus) Adenovirus Astrovirus Coxsackie Echovirus

Treatment – Viral

Focus on oral hydration Antidiarrheals not recommended Antiemetics generally not needed ◦ Phenergan black box warning <2 years ◦ Ondansetron becoming more popular Good safety and efficacy profile

(AAP, Pediatrics 1996; Ramsook, Ann Emerg Med 2002. Freedman, N Engl J Med

Signs of Dehydration Summary

PE: ◦ Abnormal Cap refill

◦ Abnormal Skin turgor

◦ Abnormal Respiratory Pattern

Protective: Normal urine Output, Nl HCO3

ORT for mild/moderate dehydration vs. IV

Dehydration in Children ORT vs IVRT in Current Practice

ORT IVRT

*Based on a national random survey of emergency physicians (N=176) selected from the American Academy of Pediatrics (AAP) Section on Emergency Medicine mailing list.3

Treatment Guidelines ORT is preferred in mild-to-moderate dehydration1

Use IVRT in severe dehydration or in children who cannot tolerate ORT1,2

Clinical Practice Realities

Use in Mild Dehydration*

71% always or almost always3 2% always or almost always3

Use in Moderate Dehydration*

15% always or almost always3 49% always or almost always3

Possible Contributing Factors Ongoing perception that ORT ineffective and takes too much time4

Parents expect an IV4

Catheter placement is one of the leading sources of pain and anxiety in children5,6

Often requires multiple attempts7-8

Is there another option?

SubCutaneous Hydration

Subcutaneous fluid administration for achieving hydration, to increase the dispersion and absorption of other injected drugs, and in subcutaneous urography for improving resaborption of radiopaque agents

Background

Subcutaneous (SubQ) administration of fluids was common from 1900 to 1950

IV route first developed in the 50s SubQ fluids safe and effective in mild to moderate

dehydration1

IV access may be difficult in dehydrated children and the elderly

Recombinant human hyaluronidase (rHuPH20) is FDA approved in subcutaneous fluid administration for

achieving hydration

1. Allen CH, Etzwiler LS, Miller MK, et al. Pediatrics. 2009;124:e858-e867.

Summary

ORAL HYDRATION THERAPY IS YOUR FRIEND!!! ◦ 5ml / 5 minutes and increase as tolerated

Alternatives? ◦ Nasogastric hydration ◦ Subcutaneous Hydration

GI – bloody diarrhea

Hemolytic uremic syndrome most common cause of ARF in children ◦Micronagiopathic hemolytic anemia ◦ Renal failure ◦ Thrombocytopenia ◦ Risk of seizures and hypertension

◦ Treatment of E.coli is risk for development

Inflammatory Bowel Disease

Crohn’s Disease ◦ Skip lesions ◦ Mouth to anus ◦ Cobblestoning ◦ Extra-intestinal manifestations

Ulcerative colitis ◦ Continuous from distal colon to proximal ◦ Significant risk of oncologic deterioration/conversion

Case

12 year male complains of abdominal pain ◦ Lasted 3 hours ◦ Obviously uncomfortable

◦ On exam, lower abdominal tenderness

◦ Further evaluation reveals…

Testicular Torsion

Salvage rate ◦ Less than 6 hours: 80-100% ◦ After 24 hours: <10%

Presence of a cremasteric reflex is possible Horizontal lie Vomiting Ultrasound with color flow

Colic / Crying – Differential

Infection: meningitis, otitis media, UTI Corneal abrasion / foreign body Intestinal obstruction Fracture Child abuse/increased intracranial pressure Incarcerated hernia Testicular torsion Hair tourniquet

Colic Criteria

Unexplained Crying for >3 hours for >3 days/week in >3 weeks

… In an otherwise healthy child.

“Neonatal bilious emesis is a surgical emergency until proven otherwise”

DIFFERENTIAL DIAGNOSIS

Infants: ◦ #1.inguinal hernia ◦ #2 intussusception

Case

3month old male presents with vomiting x1 hour ◦ can’t keep anything down

PE: small, protuberant abdomen, (+) tympanic belly

V.S. T 37.3, P 175, RR 50 PMHx: ex 33 weeker

Inguinal Hernia

INCARCERATED INGUINAL HERNIA

Most common in first year of life 30% of infant hernias present with incarceration

most manually reducible Dx by physical examination alone If abdomen distended or septic

obtain KUB to R/O free air

HERNIA REDUCTION POINTERS

Trendelenburg promotes spontaneous reduction ? Ice packs to limit edema Incarcerated bowel may be compromised

Temperature concerns Frog leg position to relax abdominal wall Quiet, calm environment limit fussiness /crying Sugar coated pacifier Keep NPO (tell parents!!)

HERNIA REDUCTION Transfix hernia, grasp testicle within scrotum Hand presses incarcerated mass through

inguinal canal Conscious sedation helpful Emergent surgery if hernia not completely

reduced, or postreduction obstruction, nonviable bowel, sepsis

If successful reduction, admit and repair when edema subsides in ≅ 24 hrs

Case Study: “Abdominal Pain”

8-year-old boy presents with 1 day of abdominal pain, fever, nausea, and vomiting.

Patient was previously healthy, although

several family members are ill. Boy is alert, has no retractions or tachypnea,

and color is normal.

Initial Assessment and Detailed Physical Examination

Initial assessment: –ABCDEs: Normal

Detailed physical examination: –Normal except for abdominal exam, which shows

tenderness in RLQ, voluntary guarding, and no rebound

–Pain had migrated from peri-umbilical area to RLQ

Management Priorities

Stop oral intake. Obtain vascular access. Begin fluid resuscitation with 20 mL/kg (500 mL)

NS.

Obtain blood and urine for laboratory analysis.

Administer pain medications. Consider antibiotics. Obtain surgical consultation.

Diagnostic Studies (1 of 2)

Laboratory There is no single specific laboratory

test that will diagnose appendicitis and rule out other causes for a child's illness. WBC is often normal.

Clinical Features: Your First Clue

Classic presentation in <50% of cases ◦ Periumbilical pain ◦ Anorexia, nausea, and vomiting ◦ Right lower quadrant pain ◦ Fever

Peritoneal irritation ◦ Percussion tenderness and rebound

Often a delay in diagnosis

Radiology: Plain Films

A fecalith is seen in 10% of cases.

May see evidence of bowel obstruction

Ultrasonography

Graded compression ultrasonography is particularly useful in the child with equivocal clinical signs.

No radiation exposure and accurate in experienced hands

Often nondiagnostic

CT Scan of Abdomen and Pelvis

High sensitivity and specificity rate Requires contrast Radiation exposure

Many institutions have elected to perform ultrasonography first.

Perform CT scan if highly suspicious of appendicitis and ultrasonography is non-diagnostic.

Case Progression/Outcome

Laboratory results showed a slightly elevated WBC.

Patient underwent ultrasonography, which showed a swollen appendix.

He was taken to the operating room. A non-perforated but inflamed appendix was removed.

Epiglottitis

Inflammation / swelling of epiglottis /surrounding tissues

H. Influenza with bacterial component

Hib vaccines have made this a rare occurrence.

Can cause complete airway obstruction, precipitated by gag reflex stimulation

Avoid examining or suctioning the upper airway

Clinical Presentation: Symptoms occur rapidly,

causing parents to seek medical attention within 24 hrs

Muffled voice Fever Stridor Labor breathing

(supraglotic edema) Drooling Usually anxious Tripod position

Epiglottitis Age Wide range: newborn to adults Average pediatric range 2 to 7 years

Case

A 3 year old is sent in by his pediatrician at 2 AM after listening to him coughing by phone ◦ URI for 2 days ◦ cough, hoarseness and what sounds like stridor ◦ In ED, Febrile (39), running around the room, without

stridor at rest ◦ RR 30, P 100, PulsOx 99%

CXR / labs ◦ Just say NO----the history and PE favor croup

Quick recheck of immunization status ◦ Epiglottitis still possible

What can be done diagnostically?

What can be done therapeutically?

Mist therapy ◦ Doesn’t work!

Corticosteroids ◦ Effective in moderate to severe croup---PO/IM superior to

nebulized ◦ Dexamethasone (0.15 - 0.6 mg/kg) PO/IM

Racemic Epinephrine Racemic 0.05 mL/kg (max 0.5 mL) L-epinephrine (1:1,000 solution) 0.5 mL/kg (max 5 mL) Observe for 2hours—rebound unlikely afterward

Dexamethasone ◦ Oral as effective as IV

Spacers vs. Nebulizers

No difference in admission rate 95% CI ( OR: 0.4 to 2.1 )

Children’s LOS in the ED shorter mean diff: -0.62 hours 95% CI ( -0.84 to -0.40 )

No difference for LOS in adults Decreased Pulse & tremor in spacer group Each spray = 108 microgram

Cochrane Review, 2009, Cates CJ

Spacers vs. Nebulizers

Conclude ◦MDI + holding chambers produced outcomes that

were at least equivalent to nebulizer delivery ◦ Holding chambers may have some advantages

compared with nebulizers for children with acute asthma

FYI ◦MDI comes out at 60MPH ◦ Spacer decreased med deposition to pharynx by 50%

Presence, touch and voice of family / significant others...

• Does not significantly increase ICP

• Has been demonstrated to decrease ICP

Family Centered Care

Bruya (1981) Journal of Neuroscience Nursing, 13

• Family Presence during Resuscitation: • Helped recognize the seriousness of condition

• They feel presence was beneficial

• They would choose to be present again

• Helps family adjust to grieving process

Family Centered Care

AAP & ACEP. Patient and family centered care and the role of the emergency physician providing care to a child in the emergency department, Pediatrics 2006

The “risk management literature indicates that patients and families are significantly less likely to initiate

lawsuits, even when mistakes are made, if there is open and effective communication and trusting relationships

between the practitioner and the patient and family”

• NO research has shown the family presence is harmful and evidence is growing that it is beneficial

The Nuclear Question: 2008

Adults age 45 or older

Very low risk of excess cancer for one scan

High prevalence of cancer in patients over 45

May not live long enough to express mutation

Usually past reproductive age

But for a 10 year old

Long lifespan in which to manifest mutation

Immature, rapidly developing body systems, more radiosensitive

May pass mutations to progeny

Radiation exposure from CT Scans in Childhood and subsequent risk of Leukemia and Brain Tumours: A

Retrospective Cohort Study. Lancet 2012

178,604 children (ages <22yo) in U.K. (‘98-’05) ◦ No Cancer prior to first CT ◦ 283,919 CT scans (64% Head CT) Leukemia = 74 Brain Tumors = 135

Compared to children with <5mGy RR Leukemia was 3.18 in those received >30mGy

Brain Tumor RR 2.82 in those received >50mGy

Risks of Ionizing Radiation from Diagnostic Imaging Bottom Line

Absolute risk is small (1/10,000 Head CT) Although the risk is small, it is cumulative ◦ Statistically significant increase in cancer risks

above 50mSv The benefits of an indicated CT far outweigh

the risks

Appropriate Utilization

CT should be avoided when an US or MRI is of comparable diagnostic utility ◦ Body MR: Liver, Pancreatic, and Renal imaging ◦ US vs. CT for appendicitis in children Amer. College of Radiology appropriateness criteria

• US 8/9: Relative Radiation Level= none • CT 7/9: Relative Radiation Level= high

Rating Scale 1,2,3 =not appropriate; 4,5,6 May be appropriate; 7,8,9 Usually appropriate

What Do Families Want to Know?

The exam is needed to best care for their child The risk of the exam is real, but very low The exam is being performed with the lowest

possible risk

Explaining Radiation Risk

Families are more interested in efforts to control the risk than the actual number

After reading a handout on radiation risk: ◦ preference for CT over no imaging decreased ◦ but no families refused CT

Larson, et al. Amer. Jrnl Rad. 2007

Summary

Ionizing radiation from diagnostic imaging may cause a small increase in the risk of cancer

For an indicated CT scan, the likely benefit is far

greater than the estimated risk We should work together to make the population

exposure ALARA
