Overview

  • Drowning is a common cause of accidental injury and death, particularly in the young

  • If attempting an aquatic rescue take care not to place yourself at risk of getting into difficulty and drowning

  • Death due to drowning arises primarily as a consequence of hypoxia

  • Initial treatments should prioritise airway and breathing interventions

Introduction

Worldwide, there are approximately 450,000 deaths each year from drowning. Most occur in low- and middle-income countries, but in 2006 there were 312 accidental deaths from drowning in the UK and 3582 in the USA, an annual incidence of 0.56 and 1.2 per 100,000 population respectively. Drowning is the leading cause of accidental death in Europe in young males. It occurs most commonly during the warmer summer months (Figure 1). Contrary to popular perception, nearly half of drowning cases occur in inland waterways. Drowning in a swimming pool is relatively rare (Figure 2).

The “Utstein Style”. In it, drowning was defined as a process rather than an event: Drowning is a process resulting in primary respiratory impairment from submersion/immersion in a liquid medium. Implicit in this definition is that a liquid/air interface is present at the entrance …
