Dextrose-Containing Carrier Solution for Hyperthermic Intraperitoneal Chemotherapy: Increased Intraoperative Hyperglycemia and Postoperative Complications.

PURPOSE: Intraoperative hyperglycemia is associated with infectious complications in general surgery patients. This study aimed to determine if the use of lactated Ringer's (LR) carrier solution during hyperthermic intraperitoneal chemotherapy (HIPEC) would lower the incidence of intraoperative hyperglycemia and improve postoperative outcomes when compared with a standard 1.5% dextrose peritoneal dialysate carrier solution. PATIENTS AND METHODS: This is a retrospective cohort study of 134 patients who underwent HIPEC at the University of Colorado. Perioperative glucose levels and outcomes were compared between patients who were perfused with 1.5% dextrose peritoneal dialysate carrier solution (n = 68) versus LR carrier solution (n = 66). RESULTS: The study population consisted of patients undergoing HIPEC for appendiceal (50%), colorectal (34%), mesothelioma (8%), and ovarian cancer (5%). Intraoperative severe hyperglycemia (glucose >/= 180 mg/dL) was significantly more common among patients perfused with a dextrose-containing carrier solution versus those perfused with LR (88% vs. 21%; p < 0.001). Patients in the dextrose cohort had significantly more severe complications (39% vs. 12%; p = 0.034), infectious complications (35% vs. 15%; p = 0.011), and organ space infections (18% vs. 5%: p = 0.026) than the LR cohort. On multivariable analysis, dextrose-containing carrier solution was significantly associated with an increased risk of postoperative infectious complications (HR 5.16; p = 0.006). CONCLUSIONS: Intraoperative hyperglycemia is common when dextrose-containing carrier solution is used during HIPEC, and severe intraoperative hyperglycemia is strongly associated with an increased risk for infectious of complications following HIPEC. LR carrier solution should be routinely used to reduce intraoperative hyperglycemia and its associated risks.
