Extended information

Drowning means that a person is submerged in water due to the inhalation of water into the lungs (wet drowning) 90%) or laryngeal contracture (10% of dry drowning) caused by suffocation.

In the case of freshwater drowning, hypotonic water can seep from the alveoli into the blood vessels, causing blood dilution, increased blood volume and hemolysis, increased blood potassium, decreased sodium, nitrogen compounds, and plasma proteins, which can lead to cardiac arrest. . In the case of seawater drowning, hypertonic seawater can suck water out through the alveoli, causing blood concentration and blood volume reduction. Electrolytes diffuse into the pulmonary capillaries, resulting in increased blood potassium and sodium, and pulmonary edema.

Drowning causes systemic hypoxia and can lead to cerebral edema. Pulmonary infections can occur if sewage enters the lungs. Complications such as tachypnea, hypoxemia, disseminated intravascular coagulation, and acute renal failure may occur during the course of the disease.
