Pediatric emergency management

🚨 Pediatric Crisis Command: The Emergency Medicine Battlefield

When a critically ill child arrives in your emergency department, you have minutes-sometimes seconds-to recognize life-threatening patterns, prioritize interventions, and execute age-appropriate treatments that differ dramatically from adult care. This lesson equips you with systematic assessment frameworks, clinical decision algorithms, and evidence-based intervention protocols tailored to pediatric physiology, so you can confidently navigate high-stakes scenarios from neonatal sepsis to adolescent trauma. You'll master rapid evaluation techniques, pattern recognition skills, and age-specific treatment strategies that transform uncertainty into decisive action when every moment counts.

📌 Remember: PALS - Pediatric Advanced Life Support protocols differ fundamentally from adult care in dosing (mg/kg), equipment sizing (age-based), and physiologic responses (compensated longer, decompensate faster)

The pediatric emergency landscape encompasses unique pathophysiology where children compensate remarkably well until sudden decompensation occurs. Heart rates range from 100-160 bpm in infants versus 60-100 bpm in adults, while blood pressure thresholds drop to 70 + (2 × age) mmHg for hypotension recognition. Respiratory rates vary dramatically: 30-60 breaths/min in newborns, 20-30 in toddlers, and 12-20 in adolescents.

💡 Master This: Pediatric vital signs vary dramatically by age - memorize the 70 + (2 × age) formula for minimum systolic blood pressure and recognize that tachycardia often represents the first and most sensitive sign of shock

Weight-based dosing calculations form the cornerstone of pediatric emergency interventions. Epinephrine dosing follows 0.01 mg/kg IV (maximum 1 mg) or 0.1 mg/kg ET, while atropine requires 0.02 mg/kg (minimum 0.1 mg, maximum 0.5 mg). Fluid resuscitation begins with 20 mL/kg normal saline boluses, repeatable up to 60 mL/kg total volume.

Connect these foundational principles through systematic assessment approaches to understand how pediatric emergency protocols create life-saving interventions.

🎯 Rapid Assessment Arsenal: The Pediatric Evaluation Matrix

Appearance Assessment Framework:

• TICLS Mnemonic: Tone, Interactiveness, Consolability, Look/gaze, Speech/cry
  • Normal: Alert, interactive, consolable, tracks visually, age-appropriate vocalizations
  • Abnormal: Limp, inconsolable, poor eye contact, weak cry, altered mental status
• Glasgow Coma Scale modifications for age: 15 normal, ≤8 indicates severe brain injury
• AVPU Scale: Alert, Voice responsive, Pain responsive, Unresponsive

📌 Remember: TICLS - Tone (floppy vs normal), Interactiveness (social vs withdrawn), Consolability (calms vs inconsolable), Look/gaze (tracks vs stares), Speech/cry (strong vs weak) - abnormal findings in ≥2 categories suggest serious illness

Work of Breathing Evaluation:

• Visual indicators: Retractions (subcostal, intercostal, suprasternal), nasal flaring, head bobbing
• Auditory signs: Stridor (inspiratory = upper airway), wheezing (expiratory = lower airway), grunting (PEEP mechanism)
• Positioning: Tripod positioning, sniffing position, refusal to lie flat
• Respiratory effort: Use of accessory muscles, paradoxical breathing patterns

• Pulse quality: Strong and regular vs weak, thready, or irregular
• Capillary refill: <2 seconds normal, 2-4 seconds delayed, >4 seconds significantly delayed
• Skin perfusion: Warm and pink vs cool, mottled, or cyanotic
• Blood pressure: Often normal until late in shock progression

⭐ Clinical Pearl: Capillary refill >2 seconds combined with tachycardia identifies shock with 85% sensitivity and 98% specificity in pediatric patients

💡 Master This: The PAT assessment occurs before vital signs and provides immediate risk stratification - abnormal appearance suggests neurologic/metabolic disease, increased work of breathing indicates respiratory pathology, poor circulation reveals shock states

Systematic Primary Survey (ABCDE):

• Airway: Patency, positioning, foreign body obstruction
• Breathing: Rate, effort, air entry, oxygen saturation
• Circulation: Pulse, perfusion, blood pressure, bleeding control
• Disability: Neurologic status, glucose level, pupil response
• Exposure: Complete examination while preventing hypothermia

Age-Specific Assessment Modifications:

• Infants: Assess fontanelle tension, primitive reflexes, feeding tolerance
• Toddlers: Stranger anxiety normal, separation from caregivers increases distress
• School-age: Can localize pain, describe symptoms, cooperate with examination
• Adolescents: Adult-like presentation but may minimize symptoms or risk behaviors

Connect systematic assessment principles through recognition of specific emergency patterns to understand how clinical findings guide immediate interventions.

🔥 Pattern Recognition Mastery: The Clinical Decision Matrix

Shock Recognition Framework:

• Compensated Shock Indicators:

  • Tachycardia (>150 bpm infants, >120 bpm children)
  • Normal blood pressure (systolic >70 + 2×age)
  • Delayed capillary refill (2-4 seconds)
  • Cool extremities with central warmth
  • Decreased urine output (<1 mL/kg/hr)

• Decompensated Shock Indicators:

  • Hypotension (systolic <70 + 2×age)
  • Altered mental status (GCS <15)
  • Prolonged capillary refill (>4 seconds)
  • Weak or absent peripheral pulses
  • Oliguria or anuria

📌 Remember: SHOCK - Systolic BP low, Heart rate high, Output decreased (urine), Capillary refill delayed, Kids compensate until they crash - recognize compensated phase before decompensation occurs

• Upper Airway Obstruction: Inspiratory stridor, suprasternal retractions, muffled voice
• Lower Airway Obstruction: Expiratory wheeze, prolonged expiration, intercostal retractions
• Lung Parenchymal Disease: Grunting, nasal flaring, subcostal retractions
• Pleural Space Disease: Unilateral decreased breath sounds, asymmetric chest movement

Neurologic Emergency Patterns:

• Increased ICP: Cushing's triad (hypertension, bradycardia, irregular respirations), papilledema, sunset eyes
• Status Epilepticus: Continuous seizure >5 minutes or recurrent seizures without return to baseline
• Meningitis: Fever, neck stiffness, photophobia, petechial rash

⭐ Clinical Pearl: Fever >38.5°C in infants <3 months requires full sepsis workup including lumbar puncture, blood cultures, and empiric antibiotics within 60 minutes

💡 Master This: Pattern recognition accelerates diagnosis - stridor + drooling + tripod position = epiglottitis, wheeze + retractions + accessory muscle use = asthma exacerbation, altered mental status + fever + petechiae = meningococcemia

Toxicologic Syndromes (Toxidromes):

• Anticholinergic: "Mad as a hatter, red as a beet, hot as a hare, dry as a bone, blind as a bat"
• Cholinergic: SLUDGE - Salivation, Lacrimation, Urination, Defecation, GI distress, Emesis
• Sympathomimetic: Hypertension, tachycardia, hyperthermia, mydriasis, agitation
• Opioid: CNS depression, miosis, respiratory depression

Connect pattern recognition skills through systematic treatment algorithms to understand how clinical findings translate into evidence-based interventions.

⚡ Treatment Algorithm Mastery: The Intervention Playbook

Airway Management Protocols:

• Bag-Mask Ventilation: 10-12 breaths/min for children, 20 breaths/min for infants
• Endotracheal Tube Sizing: (Age + 16) ÷ 4 for cuffed tubes, (Age + 4) ÷ 4 for uncuffed
• Rapid Sequence Intubation: Etomidate 0.3 mg/kg + Succinylcholine 1-2 mg/kg
• Difficult Airway: LMA size = (Weight ÷ 5) - 1 for emergency backup

📌 Remember: DOPE - Dislodged tube, Obstruction, Pneumothorax, Equipment failure - systematic approach to sudden deterioration during mechanical ventilation

Fluid Resuscitation Algorithms:

• Initial Bolus: 20 mL/kg normal saline over 10-20 minutes
• Reassessment: Repeat bolus if persistent shock signs
• Maximum: 60 mL/kg total before considering inotropic support
• Monitoring: Urine output >1 mL/kg/hr, capillary refill <2 seconds, normal mental status

• Amiodarone: 5 mg/kg IV for VT/VF, 15 mg/kg/day for SVT
• Adenosine: 0.1 mg/kg initial dose, 0.2 mg/kg second dose

⭐ Clinical Pearl: Intraosseous access achieves 95% success rate within 60 seconds when peripheral IV access fails - insert at proximal tibia or distal femur in children

💡 Master This: Treatment algorithms prioritize airway, breathing, circulation in sequence - never proceed to next step until current intervention stabilizes the patient or maximum therapy achieved

Specific Emergency Protocols:

• Anaphylaxis: Epinephrine 0.01 mg/kg IM (maximum 0.5 mg), H1/H2 blockers, corticosteroids
• Status Epilepticus: Lorazepam 0.1 mg/kg IV or Midazolam 0.2 mg/kg IM, repeat once
• Diabetic Ketoacidosis: Normal saline 10-20 mL/kg, insulin 0.1 units/kg/hr after initial hydration
• Septic Shock: Antibiotics within 60 minutes, fluid resuscitation, vasopressors if fluid-refractory

Advanced Life Support Algorithms:

• Pulseless Arrest: CPR 30:2 (single rescuer) or 15:2 (two rescuers), epinephrine q3-5min
• Bradycardia: Atropine if symptomatic, epinephrine if persistent, pacing if refractory
• Tachycardia: Adenosine for SVT, amiodarone for VT, synchronized cardioversion if unstable

Connect treatment algorithms through monitoring protocols to understand how interventions require continuous assessment and adjustment.

🔬 Diagnostic Integration Hub: The Evidence Synthesis Engine
