Near-drowning.
Near-drowning is defined as survival for at least some period of time after suffocation from submersion in a liquid. This article is a comprehensive review of the demography, pathophysiology, treatment, and prevention of near-drowning, an accident that affects approximately 6,000 to 7,000 Americans per year. Forty percent of these victims are children younger than 5 years. Alcohol plays a role in approximately one-half of near-drownings of older victims. Major factors prolonging survival are an age of less than 2 years and immersion in cold water (less than 20 degrees C). Hypoxia and acidosis are the primary physiological derangements, and treatment must be directed toward their correction. The hypothermic patient requires special considerations. The role of aggressive cerebral resuscitation has not been elucidated. Prevention of the circumstances that lead to near-drowning must be stressed as a public service.
