ABSTRACT
Despite known risks of hyperglycemia on postoperative complications, the influence of intraoperative dexamethasone on blood glucose has yet to be evaluated within the diabetic limb salvage population. This study aimed to assess the effect of intraoperative dexamethasone on postoperative blood glucose in diabetic patients undergoing atraumatic major lower extremity amputations. A single-center retrospective review of diabetic patients undergoing below-knee amputation between January 2017 and December 2022 was performed. Blood glucose levels for the 5 days before and after amputation were recorded and compared with the primary endpoints of postoperative hyperglycemia (>200 mg/dL) and glucose variability (>200 mg/dL). Cohorts were divided by patients who did and did not receive intraoperative administration of dexamethasone. Three hundred eighty-one were screened for eligibility with 180 patients included. Of these, 50 patients received dexamethasone intraoperatively (38.5%). Average pre- and postoperative blood glucose, rate of pre- and postoperative hyperglycemia, perioperative glucose variability, and postoperative dehiscence and infection were comparable between cohorts. On multivariate analysis, intraoperative administration of dexamethasone was not associated with postoperative hyperglycemia (p = .104) or perioperative blood glucose variability > 200 mg/dL (p = .334). Perioperative blood glucose variability > 200 mg/dL was associated with higher odds of surgical site infection (SSI) (odds ratio 5.12, p = .003). Administration of intravenous dexamethasone to diabetic patients undergoing below-knee amputation is not associated with postoperative hyperglycemia or complications. This study confirms previous findings that high glucose is a predictor of SSI. Concerted effort by a multidisciplinary team to attain tight glycemic control is critical to optimizing healing.
