Drowning & Near-Drowning

Also known as Drowning · Near-drowning · Submersion injury · Secondary drowning · Surfactant dysfunction drowning

The drowning — the respiratory the impairment from the submersion / the immersion in the liquid. The aspiration → the surfactant the dysfunction → the atelectasis, the V/Q the mismatch, the ARDS. The hypoxia → the brain the injury (the leading the cause of the death). The EARLY the CPR (the NOT the Heimlich), the 100 per cent the oxygen, the lung-the-protective the ventilation, the PEEP. NOT prophylactic antibiotics / the steroids. The TTM for the comatose.

The one-line answer

Drowning is the process of experiencing respiratory impairment from submersion or immersion in liquid — a single hypoxia-driven disease in which every downstream consequence (ARDS, asystolic arrest, brain injury) is secondary to failed oxygenation. The treatment ladder in one breath: ventilation first (5 rescue breaths then 30:2 — NOT the Heimlich, NOT compression-only), 100 per cent oxygen and PEEP to recruit the surfactant-washed lung, lung-protective ventilation for the ARDS pattern, targeted temperature management at 32 to 36 degrees C for the comatose, and NO prophylactic antibiotics or steroids. Cold water is protective — keep going until the patient is warm and dead.[1][3][8]

Meet the patient

A 32-year-old surfer is pulled from cold surf after an estimated eight minutes submerged. Bystanders gave five rescue breaths and chest compressions; return of spontaneous circulation came at twelve minutes. He arrives intubated, core temperature 31 degrees C, copious pink froth in the tube, and a chest X-ray white from hilum to periphery.[1][3]

Two questions decide his next hour, and they decide every drowning: is the lung recruitable? (PEEP answers that) and will the brain recover? (submersion time and water temperature answer that). Hold those two and the management slots into place.[3][6]
