Effect of basal insulin dosage on blood glucose concentration in ambulatory surgery patients with type 2 diabetes

Our study shows that the percent of normal insulin dose given the evening before surgery directly impacts perioperative glucose levels in ambulatory surgery patients. Patients taking 60%-87% of their usual dose the evening before surgery were likely to arrive in target blood glucose range with decreased risk for hypoglycemia. The mean and mode dose taken in Group 3 were 73% and 75%, respectively, suggesting that the optimal dose may be 75% of normal dose.
