A delayed drowning death case with histological findings of shock was described. The person was sustained by continuous positive-pressure respiration and died 2 days after resuscitation from drowning. The histological findings were intravascular microthrombi, hyaline bodies and fibrin thrombi in the brain, multiple megakaryocytes in the pulmonary capillaries, hyaline membranes of the lung, multiple small hyaline bodies in the liver sinusoids, and erosion of the mucous membrane of the stomach as well as histological findings of shock kidney. Drowning and systemic hypotension during resuscitation seemed to cause irreversible oxygen debt of the organs and the tissues to lead to shock.
