Shamavonian, R., McLachlan, R., Fisher, O. M., Valle, S. J., Alzahrani, N. A., Liauw, W., & Morris, D. L. (2019). The effect of intraoperative fluid administration on outcomes of patients undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy. Journal of Gastrointestinal Oncology, 10 (2), 235-243.
Background: Determine the effect of intraoperative fluids (IOFs) administered during cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) on postoperative patient outcomes.
Methods: Retrospective cohort study of patients that underwent CRS/HIPEC from February 2010 to June 2017.
Results: A total of 335 patients formed the cohort study. Patients who received higher IOFs had longer hospital length of stay (LOS) (34 vs. 22.5 days; P<0.001), extended intensive care unit (ICU) admission (5.3 vs. 3.2 days; P<0.001) and a 12% increase in grade 3/4 complications (P<0.001). Greater amounts of blood product transfusion were associated with longer hospital LOS (33.7 vs. 23 days; P<0.001), and ICU admission (5 vs. 3.4 days; P<0.001) and 12% increase in grade 3/4 complications (P<0.001). When corrected for weight and peritoneal cancer index (PCI), increased transfusion of blood products still resulted in longer hospital LOS (31.2 vs. 25.2 days; P=0.04) and longer ICU admission (4.7 vs. 3.6 days; P=0.03). On multivariable analysis, less blood product transfusions demonstrated a decreased LOS in hospital by 4.8 days (P=0.01) and fewer grade 3/4 complications (OR 0.59; 95% CI, 0.35–0.99; P=0.05).
Conclusions: Greater IOF administration is associated with an increase in postoperative morbidity, including hospital LOS, ICU admission and grade 3/4 complications, in patients undergoing CRS/HIPEC.
