![]() The aim of our study was to allow routine use of point-of-care ultrasound (POCUS) of gastric contents to assess aspiration risk and guide anesthetic management in trauma patients.Ī prospective observational study was conducted at the Ain Shams University Hospital Emergency Department. the presence of solid particles and/or gastric volume < 1.5 ml/kg), the risk of occurrence of aspiration pneumonia during the perioperative period. Ultrasonographic measurement of the antral cross-sectional area (CSA) may determine, based on the size of the stomach (i.e. Preoperative gastric content determination helps the anesthesiologist to assess the risk of pulmonary aspiration. The routine use of bedside ultrasound provides valuable information about the volume and type of gastric contents. The presence of residual gastric contents at the time of induction of anesthesia is an important risk factor of aspiration pneumonia. Pulmonary aspiration of gastric contents is rare in elective surgical groups but is more common in trauma patients requiring emergency surgery because trauma affects gastric motility and emptying. registry number: NCT04083677 on September 6, 2019. The data obtained can influence the choice of anesthesia technique and reduce the risk of aspiration pneumonia. Ultrasound examination of the stomach in polytrauma patients allows assessing the size and type of stomach contents. In all cases, no aspirations were documented. Of the 45 polytrauma patients, the risk assessment of aspiration and the anesthesia technique changed in 14 patients (31.1%) after the gastric ultrasound examination.Ī very good relationship existed between the expected stomach volume at the RLD position and the suction volume in the nasogastric tube. This was followed by routine placement of the nasogastric tube to aspirate and calculate the volume of the stomach contents. Prior to induction of anesthesia in the emergency department, gastric ultrasound was performed for qualitative and quantitative assessment of the gastric antrum in a supine position and right lateral decubitus (RLD) position. MethodsĪ prospective observational study of 45 polytrauma patients undergoing emergency surgery under general anesthesia was carried out. Gastric antral ultrasound can provide reliable information about the size of the gastric antrum in traumatized patients undergoing emergency surgery. To assess the gastric volume, a reliable diagnostic tool is needed to prevent the occurrence of aspiration pneumonia, which remains a serious complication associated with anesthesia. Polytrauma patients are at a higher risk of delayed gastric emptying.
