However, data are limited concerning the effects of carbohydrate loading on preoperative hyperglycemia and possible impacts on complication rates.Methods A prospective cohort study was performed of patients enrolled in an enhanced recovery after surgery pathway at a single institution. All patients underwent laparotomy for known or suspected gynecologic malignancies. Patients who had been diagnosed with diabetes preoperatively and those prescribed total parenteral nutrition by their providers were excluded. Data regarding preoperative carbohydrate loading with a commercial maltodextrin beverage, preoperative glucose testing, postoperative day 1 glucose, insulin administration, and complications (all complications, infectious complications, and hyperglycemia-related complications) were collected. The primary endpoint of the study was the incidence of postoperative infectious complications, defined as superficial or deep wound infection, organ/space infection, urinary tract infection, pneumonia, sepsis, or septic shock.Results Of 415 patients, 76.9% had a preoperative glucose recorded. The mean age was 60.5±12.4 years (range 18–93). Of those with recorded glucose values, 30 patients (9.4%) had glucose ≥180 mg/dL, none of whom were actually given insulin preoperatively. Median preoperative glucose value was significantly increased after carbohydrate loading (122.0 mg/dL with carbohydrate loading vs 101.0 mg/dL without, U=3143, p=0.001); however, there was no relationship between carbohydrate loading and complications. There was a significantly increased risk of hyperglycemia-related complications with postoperative day 1 morning glucose values ≥140 mg/dL (OR 1.85, 95% CI 1.07 to 3.23; p=0.03). Otherwise, preoperative and postoperative hyperglycemia with glucose thresholds of ≥140 mg/dL or ≥180 mg/dL were not associated with increased risk of other types of complications.Discussion Carbohydrate loading is associated with increased preoperative glucose values; however, this is not likely to be clinically significant as it does not have an impact on complication rates. Preoperative hyperglycemia is not a risk factor for postoperative complications in a carbohydrate-loaded population when known diabetic patients are excluded.Precis While glucose increased with carbohydrate loading in non-diabetic patients, this was not associated with complications.
