Cause of hemolysis and DIC in near drowning?

Answer 1

in FRESH WATER DROWNING, the water is HYPOTONIC as compared to the blood, so when it enters the lungs and through the alveoli, seeps into the blood vessels and ultimately the RBCs (water following the osmotic gradient)...the RBCs ultimately swell n burst open...HEMOLYSIS.

Answer 2

Hemolysis, or the breakdown of red blood cells, and disseminated intravascular coagulation (DIC), a condition causing abnormal blood clotting, can occur in near drowning due to several factors. Near drowning can result in hypoxia and acidosis, which can damage red blood cells and trigger the release of substances that activate the coagulation cascade. Additionally, the trauma and tissue damage from the near drowning event can also contribute to the development of hemolysis and DIC.
