BACKGROUND: Up to 3% of patients undergoing heart surgery suffer from an intraabdominal complication (IAC). These complications carry a high mortality besides adding to the morbidity and cost. This review was undertaken to see if a subset of patients with increased risk of IAC could be identified. METHODS: Medical records of 7,731 consecutive patients undergoing heart surgery in a single center were screened for identification of postoperative IAC. One hundred and twenty (120) cases were found. One hundred and six (106) cases were compared with the same number of matched controls. RESULTS: Significant predictors of the development of IAC were increased cardiopulmonary bypass times (> 99 minutes), peripheral vascular disease, chronic steroid use, and low left ventricular ejection fraction. Patients on postoperative antiplatelet therapy or warfarin had a lower risk of IAC. Significant predictors of mortality in IAC were increased cardiopulmonary bypass times (> or = 120 minutes.), use of inotropes, cerebral vascular disease, and incremental age. CONCLUSIONS: A subset of patients can be identified who are at higher risk for IAC and an associated adverse outcome. Patients who have prolonged cardiopulmonary bypass, have a low left ventricular ejection fraction, are on steroids, and suffer from other vascular disease should be observed carefully for development of IAC. Postoperative anticlotting strategies may be helpful. Early diagnosis and intervention are essential for improving outcomes in cases of IAC.
