[A retrospective study of neurogenic pulmonary edema following intracranial injury without open wound].

To find factors that relate to the occurrence of neurogenic pulmonary edema(NPE) following intracranial injury without open wound, thirty-founr autopsies on such cases were studied retrospectively. The rate of NPE in the 34 cases was 41.18%, and it was 44.44% in those aged 10 to 49. The rate of NPE in the persons who died immediately or 0-6 hours after injury was 41.18%, and in those who died 7-48 hours after injury, 41.18% too. The rate of NPE was 69.23% for the cases with only one site of bleeding and 23.81% for ones with multiple sites of bleeding. These findings suggest that the occurrence of NPE is not related with the duration of time after head injury or the location of brain injury, but it is related with the severity of brain injury.
