Abstract
Cardiovascular accidental cases which occurred after the injection of an enema or evacuation are reviewed. 1) The accidents occurred not only in the aged but the youth, so care should be taken at all ages. 2) They occurred especially in the patients with underlying diseases, mainly in cardiovascular or autonomous nervous systems. 3) Therefore age and basal diseases are considered separate factors. 4) Many of the cases occurred soon or in 10 minutes after evacuation. These observations are discussed in light of literatures on changes of blood pressure, mechanism related to the autonomous nervous system, treatments, and so on.
