A Study of Perioperative Hyperglycemia in Patients With Diabetes Having Colon, Spine, and Joint Surgery

Patients with diabetes often have impaired wound healing and an increased rate of postoperative complications with surgery. Most research has focused on the effect of hyperglycemia in the postoperative period, but there is limited evidence to guide blood glucose (bG) control throughout the perioperative period. This retrospective study explored the effect of hyperglycemia in the PACU on postoperative complications, length of stay (LOS), and in-hospital mortality in patients with diabetes undergoing spine, colon, or joint surgery. Findings revealed that the total LOS for patients with a PACU bG >200 mg/dL was significantly longer than for patients with a maximum bG of 140 to 200 mg/dL. Further, the rate of total complications increased significantly as bG levels increased. More prospective, controlled studies on the management of perioperative hyperglycemia are recommended for consideration.
