A Cross-sectional Observational Analysis of Preoperative Blood Glucose Levels in Nondiabetic Patients presenting for Surgery

Abstract

Introduction: Abnormal blood glucose levels alter the course and result of surgery. This study aims to quantify the incidence of hypoglycemia or hyperglycemia in the preoperative period and to assess the impact of duration of nil per os (NPO), age, intravenous fluids (IVFs), blood transfusion, severity of pain and anxiety, and steroid or antibiotic administration on preoperative blood glucose levels in nondiabetic patients.
