We report a case of gastric rupture complicating cardiopulmonary resuscitation in a 13 year old. The tear occurred on the lesser curvature of the stomach as in reported adult cases. A tear was not discovered until autopsy, despite extensive premortem investigation. In a comatose or paralyzed patient, laparotomy may be indicated in the evaluation of pneumoperitoneum following cardiopulmonary resuscitation.
