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
