Resuscitation with early ventilation, ICU management of drowning lung injury and prognosis.

Definition
Drowning = respiratory impairment from submersion/immersion in liquid. Outcomes: death, morbidity, no morbidity. Hypoxia is the primary insult; terms like 'near-drowning' and 'dry drowning' are no longer used.

At the bedside

Timed steps
  1. 1

    Cardiac arrest: ventilation first

    0 min

    Open airway and give 5 initial rescue breaths with oxygen if available, then CPR 30:2. Early intubation by a skilled operator. Do not attempt to drain water from the lungs (no Heimlich).

  2. 2

    C-spine only if indicated

    Immobilise only if diving, water-slide, trauma or alcohol with signs of injury; routine immobilisation delays ventilation.

  3. 3

    Spontaneously breathing

    High-flow oxygen; SpO2 target 94-98%; CPAP/NIV or HFNC if hypoxaemic and alert; intubate if failing, GCS ≤ 8 or exhausted.

  4. 4

    Ventilated patient

    Lung-protective ventilation (6 mL/kg PBW, PEEP 5-10+), treat as ARDS; may need high PEEP; bronchospasm and surfactant washout. Consider ECMO referral for refractory hypoxaemia.

  5. 5

    Circulation and temperature

    Hypotension from hypoxia and cold diuresis: crystalloid boluses. Treat hypothermia (see hypothermia topic). Post-arrest: avoid fever.

  6. 6

    Avoid routine extras

    No routine antibiotics (give if fever, new infiltrates beyond 48 h, or grossly contaminated water such as sewage/flood water); no routine steroids. Fresh vs salt water distinction does not change management.

  7. 7

    Disposition

    Asymptomatic with normal SpO2 and chest exam: observe for at least 6-8 h before discharge. Any symptoms, hypoxaemia, or abnormal CXR: admit.

Hypoxaemia

Oxygen

Non-rebreather
Dose
15 L/min initially; titrate to SpO2 94-98%
Red flag · call your senior now
Initially well patients can deteriorate within 4-6 h from progressive lung injury; do not discharge early.
Red flag
Submersion > 25 min or CPR > 30 min in warm water carries very poor prognosis; cold-water submersion may be associated with better outcomes.
Pitfall
Starting with chest compressions without ventilation in drowning arrest: the cause is hypoxic.
Pitfall
Routine C-collar for every drowning victim.
Pearl
Vomiting during resuscitation is very common; turn the patient and suction, keep ventilating.
Pearl
Flood/monsoon drowning in India: consider leptospirosis and aspiration of contaminated water if fever develops later.
