Hypovolaemic shock with particular reference to the myocardial and pulmonary lesions.

Amongst 207 post mortem examinations of patiens dying as a result of haemorrhage, there were 102 with histological manifestations of the shock syndrome. Shock lesions in the lung were found in 50% of cases, and in the heart shock lesions were found in 39.2%. Shock lesions in the heart were the commonest cause of shock that proved refractory to restoration of the blood volume. The pulmonary lesions of shock developed later than the cardiac lesions and in this series were the commonest cause of death.
