Project title: Metformin Continuation versus Interruption in type 2 Diabetes Patients Undergoing Ambulatory Surgery
Human subjects IRB approved project number: 032010-079
Date approved: April 9, 2010
Brief Description of Project:
The purpose of this project is two fold. The first is to compare preoperative, intraoperative and postoperative blood glucose level in type 2 diabetic patients continuing or interrupting metformin treatment in the perioperative period. The second is to determine if continuing metformin treatment results in detectable lactic acidosis. To answer the questions that this study presents, demographic information from medical records will be collected; preoperative, intraoperative (hourly) and postoperative capillary blood glucose levels will be measured; and point of care lactic acid level will also recorded before surgery and in the post anesthesia recovery. We hypothesize that uninterrupted treatment with metformin in type 2 diabetic mellitus patients undergoing ambulatory surgery will not result in intraoperative and postoperative hypoglycemia (defined as blood glucose < 70mg/dl) compared to patients withholding metformin treatment on the day of surgery.
