Treatment of Severe Hyperglycemia in Patients Without Diabetes After Colorectal Surgery.

Several studies have suggested that intravenous insulin therapy for post-operative hyperglycemia improves outcomes after colorectal surgery. Despite the potential benefit, there is a reluctance to use this approach in patients without diabetes mellitus because of an unproven benefit and the potential for hypoglycemia. In this study, we examined whether sliding-scale insulin is sufficient to improve outcomes or if stricter glucose control is necessary.
