What are the complications of drowning?

  • Hypoxemia causing brain damage is the major complication in drowning victims who do not die.
  • Direct lung tissue damage because of water aspirated into the lung can also occur and may lead to pneumonia and acute respiratory distress syndrome (ARDS).
  • If the drowning occurs in colder water, there is the risk of hypothermia or a drop in core body temperature.
  • Drowning may occur as a consequence of injury or illness. For example, cervical spine fractures (broken neck) due to diving injuries may result in breathing problems and subsequent drowning. Drowning can occur as a result of loss of syncope or loss of consciousness in the water, including seizure.

Does the type of drowning matter?

There have been a variety of theories reported regarding the potential responses of the body to different drowning situations. Most discuss dry vs. wet drowning and salt vs. fresh water drowning.

Wet vs. dry drowning

Most drownings are unwitnessed, and the victim is found floating. While only a small amount of aspirated water is required to cause significant problems with lung function, it is the prolonged submersion time and lack of breathing that causes complications due to hypoxemia.

Approximately 10% to 20% of drowning victims have dry drowning, but even most wet drowning victims have less than 4cc/kg of water found in their lungs. For a 50 pound child, this amounts to less than 3 ounces.
