Background: Anesthetic and fluid management during cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) may influence 30-day postoperative outcomes. We investigated intraoperative management differences and their relation to outcomes in all consecutive patients undergoing HIPEC and CRS following the first 2 years after initiation of this surgical oncology program in a single center. Methods: Following IRB approval we retrospectively recorded demographics, intraoperative anesthetic and fluid management and 30-day postoperative cardiopulmonary, renal, infectious, neurologic, and surgical complications, mortality and length-of-stay in patients undergoing CRS and HIPEC. The Chi-square, Fisher’s exact and Wilcoxon two-sample tests were used for statistics. A p < 0.05 was significant. Results: We identified 34 patients with a mean age of 53.9 ± 11.5 years. Postoperative complications occurred in 14 patients (41%), twelve of whom (35%) had pulmonary adverse events. Patients with complications were significantly older (p=0.04) and were significantly longer hospitalized (p=0.00). Neither primary malignancy type nor intraoperative fluid replacement differed between groups. Patients with complications had mild preoperative anemia (p=0.052).
