Optimizing Diabetes Medication Management Around Surgery

Patients with diabetes mellitus face significant risks during the perioperative period, including dangerous fluctuations in blood glucose levels. Both hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar) can lead to serious complications, impacting surgical outcomes and patient recovery. Despite these known risks, there has been a lack of clear, comprehensive guidance on how to adjust various oral agents, insulins, and noninsulin injectables to ensure optimal glycemic control while minimizing adverse events. This review addresses the critical need for standardized yet individualized protocols for managing diabetes medications before, during, and after surgery.

The review highlights that most oral and injectable diabetes agents necessitate specific adjustments both the day before and the day of surgery. For instance, insulin regimens often require significant modification to prevent both hypoglycemia due to reduced caloric intake and hyperglycemia from surgical stress. The authors emphasize that medication adjustments must be highly individualized, taking into account the patient's specific diabetes type (e.g., type 1 vs. type 2), the anticipated duration of the NPO period, and the invasiveness of the surgical procedure. They found that a one-size-fits-all approach is ineffective and potentially dangerous. The most critical finding is the imperative for individualized medication adjustments based on patient-specific factors to achieve optimal glycemic control and significantly reduce the risks of perioperative complications. This tailored approach ensures that patients maintain blood glucose levels within a safe range, balancing the need for adequate glucose for metabolic demands against the dangers of excessive insulin or oral agent activity.
