Aspiration Risk Assessment by Gastric Ultrasound in eMErgency Surgery and ANesThetic Decision-making: The ARGUMENT Study

Sponsor: Samuel Lunenfeld Research Institute, Mount Sinai Hospital

Summary

Pulmonary aspiration of gastric contents is a serious patient safety problem accounting for 50% of anesthesia-related mortality. The risk is higher in patients undergoing emergency surgery as the gastric content is uncertain which poses a challenge to anesthetic decision-making. Standard clinical assessment to identify at-risk patients primarily relies on preoperative fasting guidelines and is not adequate for patients undergoing emergency surgeries. Point-of-care gastric ultrasound (GUS) has emerged as an accurate bedside tool providing information regarding the type and volume of gastric contents. When GUS was added to standard clinical assessment, anesthetic management plan changed in 71% of adult elective and 37% of pediatric emergency surgical procedures. Such data is lacking in adult patients undergoing emergency surgeries. The investigators propose a multicentre mixed-method study to evaluate the impact of GUS on aspiration risk assessment and subsequent Anesthetic Plan before emergency surgeries. The evidence from this study will improve patient safety by accurately identifying patients at risk of aspiration and tailoring anesthetic techniques and airway management to prevent pulmonary aspiration in patients undergoing emergency surgeries.
