Drowning & Submersion Injury Nursing Care

Drowning is respiratory impairment from submersion or immersion in liquid. Water (or laryngospasm) interrupts breathing → hypoxia → and if not reversed, cardiac arrest and anoxic brain injury. The water damages surfactant and the alveolar-capillary membrane, causing pulmonary edema and impaired gas exchange — which can progress to ARDS. The brain is the other target organ, vulnerable to anoxic injury and cerebral edema.

Terminology has changed: use “drowning” (fatal or nonfatal) and abandon the old terms “near-drowning,” “dry vs wet,” and “secondary drowning” — they’re imprecise. Freshwater vs saltwater distinctions are largely academic; the duration of hypoxia is the key prognostic factor.

Assess airway, breathing, and oxygenation continuously: respiratory rate and effort, work of breathing, cough, crackles/wheeze, SpO₂, and mental status. Note the submersion time and water type/temperature if known. Watch for evolving pulmonary edema/ARDS (worsening hypoxia, increasing work of breathing, diffuse crackles), neuro status (anoxic injury, cerebral edema), core temperature (hypothermia), and arrhythmias. Screen for associated trauma and the precipitating cause, and check glucose and a tox screen as indicated.

Drowning, especially of a child, is catastrophic and saturated with guilt (“I only looked away for a second”). Provide nonjudgmental support, accurate but compassionate information about prognosis, and chaplain/social-work support. Avoid feeding the “dry/secondary drowning” panic that circulates online — give families clear, specific return-precaution instructions instead. When neglect or abuse must be assessed, do so factually and per policy while still supporting the family.

Prevention is overwhelmingly the answer: constant, close, undistracted supervision of children near any water (including bathtubs and buckets), four-sided isolation pool fencing with self-latching gates, life jackets (not floaties) for boating and weak swimmers, swim lessons, and avoiding alcohol around water. Teach CPR to caregivers — bystander resuscitation improves outcomes. At discharge after a nonfatal drowning, give explicit warning signs to return for: increasing trouble breathing, persistent cough, sleepiness or confusion, or vomiting. For patients with seizure disorders, counsel on water-safety precautions (showers over baths, never swim alone).
