Management of Drowning in Pediatric Age

Introduction to Pediatric Drowning Management

Definitions and Classification

  • Drowning: Process of experiencing respiratory impairment from submersion/immersion in liquid
  • Submersion Time:
    • Critical factor in outcome
    • Survival unlikely after >25-30 minutes
    • Exception: Cold water drowning
  • Water Temperature Impact:
    • Warm water (>20°C): Rapid neurological deterioration
    • Cold water (<20°C): Possible protective effect
    • Ice-cold water (<5°C): Maximal protective effect

Epidemiology

  • Risk Factors:
    • Age: Peak incidence 1-4 years
    • Gender: Males > Females
    • Location: Home pools, natural water bodies
    • Supervision gaps
    • Lack of barriers/safety measures
  • Mortality Patterns:
    • Immediate deaths: 10-20%
    • Early deaths (<24h): 30-40%
    • Late deaths: 10-20%
    • Survival with sequelae: 20-30%

Initial Assessment

Scene Assessment

  • Critical Information:
    • Submersion duration
    • Water temperature
    • Witnessed vs unwitnessed
    • Initial rescue attempts
    • Water type (fresh/salt)
  • Safety Considerations:
    • Scene safety for rescuers
    • Multiple victim possibility
    • Environmental hazards

Primary Survey

  • Airway:
    • Clear foreign material
    • Look for airway edema
    • Assess need for intubation
    • Cervical spine precautions if trauma
  • Breathing:
    • Assess respiratory effort
    • Auscultate for crackles/wheezing
    • Check oxygen saturation
    • Look for signs of ARDS
  • Circulation:
    • Check pulses and perfusion
    • Assess heart rate and rhythm
    • Look for signs of shock
    • Monitor blood pressure

Initial Vital Signs

Parameter Severe Moderate Mild
GCS ≤8 9-12 13-15
SpO2 <85% 85-92% >92%
Respiratory Rate Apnea/Gasping Tachypnea Normal

Resuscitation Protocols

Immediate Actions

  • Cardiac Arrest Management:
    • Begin high-quality CPR immediately
    • Use appropriate compression depth
    • Ensure adequate recoil
    • Minimize interruptions
  • Airway Management:
    • Early intubation if GCS ≤8
    • Use cuffed ETT when indicated
    • Consider video laryngoscopy
    • Prepare for difficult airway

Ventilation Strategy

  • Initial Settings:
    • PEEP: 5-10 cmH2O
    • Tidal Volume: 6-8 mL/kg
    • FiO2: Start 100%, titrate down
    • Target SpO2: 94-98%
  • ARDS Protocol:
    • Higher PEEP strategy
    • Permissive hypercapnia
    • Prone positioning if severe
    • Consider HFOV in refractory cases

Medication Protocols

Medication Indication Dose Notes
Epinephrine Cardiac arrest 0.01 mg/kg Q3-5 min
Midazolam Sedation 0.1 mg/kg Titrate to effect
Vecuronium Paralysis 0.1 mg/kg If indicated

Critical Care Management

Temperature Management

  • Hypothermia Protocol:
    • Target temp: 32-34°C if indicated
    • Duration: 24-72 hours
    • Rewarming: 0.25-0.5°C/hour
    • Monitoring for complications
  • Rewarming Techniques:
    • Passive external
    • Active external
    • Active internal
    • ECMO if indicated

Neurological Care

  • Monitoring:
    • Continuous EEG
    • ICP monitoring if indicated
    • Serial neurological exams
    • Pupillary responses
  • Management:
    • Maintain CPP >40 mmHg
    • Treat seizures aggressively
    • Control fever
    • Monitor electrolytes

Organ Support

  • Respiratory:
    • Lung-protective ventilation
    • Regular recruitment
    • Surfactant if indicated
    • Consider ECMO
  • Cardiovascular:
    • Maintain adequate BP
    • Support cardiac function
    • Monitor fluid balance
    • Treat arrhythmias
  • Renal:
    • Monitor urine output
    • Check renal function
    • Consider CRRT if needed
    • Manage electrolytes

Complications and Management

Early Complications

  • Respiratory:
    • ARDS (40-60% cases)
    • Pneumonia
    • Atelectasis
    • Pulmonary edema
  • Neurological:
    • Cerebral edema
    • Seizures
    • Increased ICP
    • Brain death

Late Complications

  • Neurological Sequelae:
    • Cognitive impairment
    • Motor deficits
    • Visual/hearing problems
    • Behavioral changes
  • Systemic:
    • Chronic lung disease
    • Renal dysfunction
    • Psychological trauma
    • Growth issues

Prognostic Factors and Outcomes

Key Predictors

  • Major Factors:
    • Submersion duration
    • Time to ROSC
    • Initial GCS
    • Water temperature
  • Scoring Systems:
    Factor Good Prognosis Poor Prognosis
    Submersion Time <5 minutes >10 minutes
    CPR Duration <10 minutes >25 minutes
    Initial pH >7.1 <6.8

Prevention Strategies
