Seventeen World War II veterans were studied to determine the relation between depth of coma in insulin coma treatment and the occurrence of vividly experienced sensations of death. It was not always possible to correlate occurrence of death phenomenon with the level of coma, since opinions as to level of coma can vary and patients having similar experiences may use different terms to describe them. The author concludes that there is no positive correlation between the occurrence of the death experience in patients undergoing insulin coma treatment and the depth of the coma.
