Bedside Gastric Ultrasound for Assessment of ASA Preoperative Starving Guidelines Accuracy: Diabetic vs Non Diabetic Patients

To reduce the risk of perioperative pulmonary aspiration of gastric contents, oral intake of liquids or solids is not allowed for certain periods. Recently, the ultrasound (US) is used to evaluate the volume and the nature of the stomach content. In its latest recommendations, the American Society of Anesthesiologists (ASA) shortened the duration preoperative fasting. The aim of the study is to evaluate the efficacy of ASA recommendations in diabetic patients using ultrasound (US) scanning of the stomach (antrum).
