Key result
Bedside gastric ultrasonography identified high aspiration risk in 18% of patients and led to a change in anesthetic management in 25% of cases, with no instances of pulmonary aspiration observed.
Why the study?
Fasting guidelines to prevent pulmonary aspiration do not apply to acute patients or certain conditions, and gastric ultrasonography may quantify gastric content to evaluate aspiration risk.
Does bedside gastric ultrasonography change anesthesia procedures in patients undergoing anesthesia?
Observational (n=96)
No
Does bedside gastric ultrasonography change anesthesia procedures in patients undergoing anesthesia?
Answers are grounded in this paper and cite their sources.
Gastric ultrasound may prompt anesthesia changes in select patients; leaves open whether it reduces aspiration risk without prospective trials.
Background: Pulmonary aspiration is a serious complication of anesthesia. For prevention, fasting guidelines have been made, but they do not apply to acute patients or patients with certain conditions. In addition to known prevention, gastric ultrasonography is believed to help to quantify the amount of gastric content and predict the risk for pulmonary aspiration. In this study, changes in anesthesia procedure after gastric ultrasound were investigated.

Hauke et al. (2020) conducted an observational in Patients undergoing urgent or elective surgery (n=96). Bedside gastric ultrasonography was evaluated on Change in anesthetic management. Bedside gastric ultrasonography identified high aspiration risk in 18% of patients and led to a change in anesthetic management in 25% of cases, with no instances of pulmonary aspiration observed.
