DETERMINING GASTRIC EMPTYING TIME IN ELDERLY USING ULTRASOUND ASSOCIATED WITH PREOPERATIVE FASTING TIME Background: Gastric contents aspiration is the most crucial complication of general anaesthesia. There are limited studies to assess the gastric volume ultrasound to clarify an appropriate fasting time before surgery. Gastric content will examine after a traditional Turkish breakfast with ultrasound. Methods: After the first ultrasound examination by asking 8 hours fasting ,gastric emptying time(GET) was determined by serial gastric ultrasound examinations with two ultrasonographers and GET identified by real time USG evaluations in every 1 hour. All ultrasound assessments on volunteers will made both in the supine position and right lateral decubitus (RLD) from the epigastric area by using a convex probe. This study is the first one which examine gastric emptying time after a standard Turkish breakfast in over 65 years Turkish population by measuring antral cross section area (CSA) using noninvasive ultrasound.
