Abdominal complications following cardiac surgery.

Type and frequency of abdominal complications after open heart surgery are described. Out of 3,312 patients, 48 patients (1.4%) developed early postoperative abdominal complications with a mortality rate of 14.5%. Paralytic ileus, erosive gastritis and gastrointestinal hemorrhage were the most frequent complications, whilst intestinal ischemia, acute cholecystitis and acute pancreatitis were less frequently observed. The comparison of the frequency of abdominal complications in cardiac surgery patients with the same complications in other operated patients showed no significant difference (hi-square test), with the exception of COLD which was more frequent in the group with abdominal complications. No association was found between perioperative treatment with aprotinine and the development of abdominal complications.
