Abstract

Fasting has been the standard of many medical procedures such as upper endoscopic procedure, surgery, bronchoscopy and abdominal ultrasound imaging. Generally, the fasting recommendations follow The Canadian Anesthetist's Society (CAS) and American Society of Anesthesiologists (ASA) guidelines. In that recommendation, patients only received clear liquid which contains simple carbohydrate or water two to six hours prior to surgery. After three hours of meal body has to provide nutritions for itself by gluconeogenesis. In addition to nutritional issues, gastric irritation and dehydration occur as well. All these conditions can have adverse effects on the patients pre and post-surgical outcomes. Oral nutritional supplements (ONS) contain complete nutrient is a standard formula which could be given as an option to the patients undergoing surgery or endoscopic procedures. In a preoperative period, besides providing adequate nutrients, ONS also improves patient satisfaction. We present a case of gastric emptying of 200 ml ONS assessed by ultrasound. The ONS when tracked by the ultrasound resulted in passing through the stomach within two hours. We suggest that 200 ml ONS can be given to patients two hours prior to medical and surgical procedures.
