Perioperative hypoglycemia in patients with diabetes: incidence after low normal fasting preoperative blood glucose versus after hyperglycemia treated with insulin.

Perioperatively, insulin to treat hyperglycemia is administered judiciously to minimize the risk of hypoglycemia. In patients with diabetes in whom preoperative blood glucose levels are on the low end of normal, hypoglycemia risk may be underestimated. This retrospective study enrolled subjects with presenting preoperative blood glucose values in these ranges: 70 to 89 mg/dL (low normal group) and above 249 mg/dL (hyperglycemia-treated group).

Insulin glargine dosing before next-day surgery: comparing three strategies.

Study Objective: To evaluate three evening insulin glargine dosing strategies for achievement of target (100-179 mg/dL; 5.5 - 9.8 mmol/L) and widened (80-249 mg/dL; 4.
