This is contrary to common wisdom that laryngospasm prevents water aspiration in majority of victims, who go on to die of hypoxia without water entering the lungs.46 Determinations of lung weights and volumes from autopsies of drowned victims have shown evidence of death without aspiration of water in about 2% of the cases.47. Kriz D, Piantino J, Fields D, Williams C. Children (Basel). Immersion is to be covered in water; thus for drowning to occur, at least the face and airway are immersed.

In this review, passive external, active external, and active internal rewarming techniques for treatment of hypothermic patients are discussed. The manifestations of the hypoxic injury are often immediate and severe, displaying the entire spectrum found in other forms of hypoxic-ischemic encephalopathy (see Chapter 104). Uncontrolled involuntary hyperventilation occurs in immersion in a cold medium. The victim drowns from loss of consciousness in the water but immersion syndrome is the initiating factor. Pediatric Hypothermic Submersion Injury and Protective Factors Associated with Optimal Outcome: A Case Report and Literature Review. Adolescents often drown in rivers, lakes, and canals.

All other resuscitative measures should be instituted according to current pediatric advanced life support protocols until arrival at the nearest medical facility. Typhoons, tropical storms, and floods count as the most common mode of disaster, affecting close to 49 million individuals in a ten-year span. The traditional teaching that seawater draws water from the intravascular spaces into the lungs by osmosis, resulting in fluid-filled alveoli and hypovolemia, and freshwater results in water absorption into the vascular space and hyper-volemia and hemolysis is based on impeccable physiologic reasoning. If you continue browsing the site, you agree to the use of cookies on this website. NLM National Center for Injury Prevention and Control). Younger victims, however, may not struggle, but simply sink and drown quietly. Med Gas Res. The neurologic injuries are by far the main outcome determinant after submersion injuries.

Hypothermia can cause hypotension and bradycardia; the latter should not be interpreted automatically as a more ominous sign of brain herniation. J Trauma 2001; 51:658. 1983 Dec;1(3):643-52.

The single most important consequence of near-drowning is hypoxemia often associated with acidosis. A thorough physical examination and a detailed history are essential to define the circumstances of the event and to identify traumatic injuries that may not be apparent initially.

The traditional teaching that seawater draws water from the intravascular spaces into the lungs by osmosis, resulting in fluid-filled alveoli and hypovolemia, and freshwater results in water absorption into the vascular space and hyper-volemia and hemolysis is based on impeccable physiologic reasoning. Similarly, it stands to reason that water entry into the lungs should wash out pulmonary surfactant or inactivate surfactant’s surface tension properties.46,49,50 Once again, the extent to which surfactant deficiency contributes to the alveolar collapse and gas exchange abnormalities seen after submersion injuries is not well defined.
