BACKGROUND: Management of patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CS/HIPEC) has historically favored liberal fluid administration owing to lengthy duration of surgery and hyperthermia. This practice has been challenged in recent years with studies demonstrating improved outcomes with restrictive fluid administration. METHODS: Patients who underwent CS/HIPEC between March 2010 and September 2018 were included for analysis. Patients who received an above-median fluid rate (high-IVF) versus below-median fluid rate (low-IVF) were compared, and multivariate analyses were performed for length of stay, 90-day unplanned readmissions, and major complications. RESULTS: The 167 patients had a mean age of 56.7 ± 11.4 years and body mass index of 29.5 ± 6.9 kg/m2. The median rate of total intraoperative crystalloid and colloid was 7.4 mL/kg/h. The low-IVF group had less blood loss (183 vs. 330 mL, p = 0.002), were less likely to need intraoperative vasopressor drip (2.4% vs. 11.9%, p = 0.018), and experienced fewer cardiac complications (2.4% vs. 10.7%, p = 0.031), pneumonias (0% vs. 6.0%, p = 0.024), and Clavien-Dindo grade 3-5 complications (14.5% vs. 33.3%, p = 0.004). Multivariate analyses identified bowel resection (HR 4.65, p = 0.0008) as a risk factor for 90-day unplanned readmission, while bowel resection, intraoperative fluid rate, and estimated blood loss were associated with increased length of stay. CONCLUSION: Higher intraoperative fluid intake was associated with multiple postoperative complications and increased length of stay, and represents a potentially avoidable risk factor for morbidity in CS/HIPEC.
