The present study of the causes of postoperative death of obese patients was undertaken to determine, if possible, the cause of the increase in mortality in such patients and what measures might be taken to reduce it. This involved a comparison of the causes of death of obese patients with those of a control group. The latter was made up of all patients who died following operation during the same period, without regard to weight.
BASIS OF STUDY
The history of the patient in all cases of death after operation during a period of six years (from 1920 to 1925, inclusive) was studied. A total of 156 of these patients were definitely obese. In 145 cases of this group, necropsy was performed; in the remaining eleven, the clinical cause of death seemed sufficiently clear to permit their inclusion in the group.The obesity in these 156 cases was graded from
