UMEM Educational Pearls - By Rose Chasm

  • Over the last decade, multiple studies have shown that pain and sedation in children can be easily and quickly treated via intransal administration of traditional drugs.
  • Inexpensive atomizers are used to quickly administer medications which are absorbed through the mucosal surface and rapidly delivered to the bloodstream and CNS with equivalent effects to intravenous administration.
  • Considerations include using concentrated forms as volumes greater than 1mL per nostril may over-saturate the mucosa and drip out rather than be fully absorbed.
  • The few side effects included cough, vocal cord irritation, and laryngospasm; but pre-treating with a single puff of lidocaine spray minimizes them and has been found to enhance sedative effects.
  • Fentanyl, 2mcg/kg for pain
  • Midazolam, 0.2 - 0.5mg/kg for sedation and antiepileptic.
  • Ketamine and Dexmedetomidine have also been used with success, but standardized doses are still being studied.

  • Male infants are routinely given a sweet solution prior to circumcision for analgesia.
  • Michelis and Hoyle recently published a great review of the possible use of sweet solutions in the ED for pediatric patients.
  • Pediatric patients often undergo painful, but rather routine procedures in the ED such as IV and urinary catheter placement, venipuncture, and lumbar punctures.
  • More often than not, however, they are not provided analgesia prior to these procedures.
  • It is believed that repetitive early pain events lead to anxiety and other behavioral disorders while also decreasing pain tolerance.
  • In children less than 12 months, consider giving a sweet solution (2mL of 24% sucrose) 2 minutes before any painful procedure.
  • Multiple studies indicate decreased pain as measured by significantly reduced crying times.
  • It's cheap, safe, and works!

  • Much attention has been paid towards early goal-directed therapy for sepsis in adult ED patients, but there has not been as much consideration for the pediatric ED patient. 
  • R-C analyses and M&M reviews have consistently identified system difficulties  recognizing sepsis in children, especially cases of compensated shock, and subsequent management.
  • Protocols beginning in triage to recognize abnormal vital signs, followed by timely execution of interventions especially antibiotic and fluid administration are worthwhile to reduce overall morbidity and mortality.
  • Protocols should include 3 major goals:
  1. Triage vital signs adjusted for age, and corrected heart rate for pyrexia to recognize sepsis.
  2. Obtain vascular access within 5 minutes followed by a 20mL/kg bolus of IV fluids administered within 15 minutes in cases of volume depletion.
  3. Antibiotic administration within 30 minutes.

  • Significant morbidity and mortality has been consistently documented in pediatric sickle cell patients due to overwhelming sepsis from encapsulated organisms, especially S. pneumoniae
  • All pediatric sickle cell patients presenting with fevers greater than 101.5F (38.6C) should receive antibiotics within 60 minutes of triage.
  • Historically, and still in many pediatric sickle cell centers, ceftriaxone (75mg/kg/dose) is administered
  • However, reported cases of deadly intravascular hemolysis in pediatric sickle cell patients whom had recieved multiple doses of ceftriaxone has led to new recommendations for antibiotic coverage to include cefuroxime (200mg/kg/day) or ampicillin/sulbactam (200mg/kg/day)

  • Normal mental status
  • No scalp hematoma, except frontal
  • Loss of consciousness < 5 seconds
  • No palpalble skull fracture
  • Normal behavior
  • Nonsevere mechanism (fall < 3ft, pedestrian struck, rollover MVC)

For children > 2 years old: <0.05% risk of clinically important TBI

  • Normal mental status
  • No signs of basilar skull fracture
  • No loss of consciousness
  • No vomiting
  • No severe headache
  • Nonsever mechanism (fall < 5ft, pedestrian struck, rollover MVC)

Risk stratisfication score introducted by Maden Samuel in 2002.

The Pediatric Appendicitis Score had a sensitivity of 1, speciificity of 0.92, positive predictive value of 0.96, and negative predictive value of 0.99

Signs:

  • Right lower quadrant tenderness = 2 points
  • Cough/Percussion/Hop RLQ tenderness = 1 point
  • Pyrexia = 1 point

Symptoms:

  • RLQ migration of pain = 1 point
  • Anorexia = 1 point
  • Nausea/Vomiting = 1 point

Laboratory Values:

  • Leukocytosis = 2 points
  • Polymorphonuclear neutrophiia = 1 point

Scores of 4 or less are least likely to have acute appendicitis, while scores of 8 or more are most likely.

  • outbreaks worse in summer and fall, but is a self-limited illness
  • causes mild flu-like symptoms such as fever, headache, muscle aches, sore throat. with fever usually lasting less than 3 days
  • hand, foot, and mouth disease: syndrome of painful blisters in oropharynx and plams of hands and soles of feet
  • herpangina: painful blisters in oropharynx, usually posterior in location
  • hemorrhagic conjunctivitis: eye pain with injected conjunctivia
  • serious complications include: viral meningitis and encephalitis, myocarditis, and secondary bacterial infections

  • diarrhea lasting less than 14 days
  • in children, almost all diarrhea is due to an infectious agent
  • most etiologies are self-limited and do not need further evaluation except in the following conditions:
  1. infants < 2 months of age
  2. gross blood in stool
  3. WBC's on microscopic exam of stool
  4. toxic-appearance
  5. immunocompromised child
  6. diarrhea developing while an inpatient
  • therapy is aimed at oral rehydration and providing nutrional needs
  • ORT is best with commerical formulations specific for this as most other clear liquids (juice, sodas) are hypertonic and have excess glucose resulting in ongoing diarrhea-like stools
  • after rehydration, resume the child's normal diet.

  • CDC recommends pediatric influenza antiviral treatment for those at higher risk for influenza complications, and include the following:
  1. less than 2 years of age;
  2. chronic diseases including: pulmonary (ie asthma), cardiovascular (except hypertension alone), renal, hepatic, hematologic (ie sickle cell disease), metabolic (ie diabetes), neurologic/neurodevelopmental (ie cerebral palsy, epilepsy), and intellectual disability (ie mental retardation)
  3. immunosuppression (ie HIV)
  4. less than 19 years of age and on chronic aspirin treatment;
  5. morbid obesity (BMI>40)
  • adamantanes (amantadine and rimantadine) should not be used due to high levels of resistance to influenza A
  • neuraminadase inhibitors (oseltamivir and zanamivir) should be started within 48 hours of illness onset to reduce the duration and severity of disease
  • oseltamivir can be used in children as young as 2 weeks of age at a dose of 3mg/kg twice daily for 5 days.

  • sleep disruption silimar to a nightmare, but much more dramatic most often between 4-12 years
  • sudden fear reaction which occurs during the transition to and from deep non-REM sleep while nightmares occur during REM sleep
  • occurs 2-3 hours after falling asleep when the child suddenly awakens in distress and may thrash about, scream, cry
  • child returns to sleep with no memory of the event the following morning
  • often occurs when a child is stressed, overtired, on new medication, or sleeping in a new environment
  • do not awaken the child during the event but rather allow them to calm on their own

  • small growth of grainy pink/redish tissue that forms on an area of the umbilical stump which is inflamed and produces a sticky mucous dishcarge not allowing normal tissue to grow on top of it
  • caused by abnormal tissue healing after the remaining umbilical cord dries up and falls off
  • treatment is painless as the granuloma lacks innervation, and requires applying chemical silver nitrate directly to the granumloma to burn the tissue off
  • although rare, careful examination of the tissue is needed to enssure the tissue is not intestinal or bladder in origin

  • congenital disorder which is the most common cause of stridor in infancy
  • larynx appears disproportionately small, and supporting structures are abnormally soft
  • stridor begins within the first 4 weeks of life, and accentuates with increased ventilation (crying, excitement, URI, etc.)
  • stridor usually resolves by 12 months but may recur with URI until about 3 years of age

The summertime can be full of lots of fun activities (beach, fireworks, cookouts, and campfires) that can put children at risk of burns. 

Burn depth classification:

1. Superficial (first-degree): red and blanching with minor pain, resolves in 5-7 days 

2. Partial thickness (second-degree): red and wet with blisters, very painful, resolves in 2-5 weeks

Treatment: clean with soap and water twice daily, and apply silvadene wrap with gauze, kerlex

3. Full thickness (third-degree): dry and leathery without pain, no resolution after 5-6 weeks, may require graft

Treatment:  wound debridement and dressings as above

Parkland formula: 4ml/kg/%TBSA in 1st 24 hours with 50% of total volume in 1st 8 hours

 Calculate burn surface area:

-SAGE: free computerized burn diagram available at www.sagediagram.com

-Rule of Nines > 14 years old

  • acute gastroenteritis is a self-limited illness
  • however, damage to the brush border of the small intestine mucosa where lactase is present may lead to a secondary lactase deficiency and subsequent inability to digest lactose properly
  • partially or minimally digested lactose moves into the colon where it is fermented by enteric bacteria resulting in hydrogen, carbon dioxide, and acids
  • these byproducts result in symptoms reported for those with lactase deficiency: cramps, abominal pain and distension, and flatulence
  • the increased solute load in the large intestine leads to increased osmotic pressure, causing watery diarrhea
  • early refeeding following gastroenteritis is recommended, but many clinicians recommend dairy restricted diets acutely
