Near drowning pulmonary edema

Near drowning pulmonary edema is considered an etiological sub type of  non cardiogenic pulmonary edema. It can occur with both salt or fresh water drowning.

Pathology

It is thought to result from the inhalation of either fresh or sea water resulting in lung damage and ventilation-perfusion mismatching.

Near drowning It can be divided into three stages:

  • stage I: acute laryngospasm that occurs after inhalation of a small amount of water
  • stage II: victim still usually presents with laryngospasm but may begin to swallow water into the stomach
  • stage III
    • 10-15% of patients still present with dry drowning caused by persistence of the associated laryngospasm
    • in the remaining 85 - 90% of patients, the laryngospasm relaxes secondary to hypoxia and large amounts of water are aspirated
