The role of gastric ultrasound in anaesthesia for emergency surgery: A review and clinical guidance
Authors' conclusion
The preoperative presence of gastric content before emergency surgery is high and the estimates used for clinical management are unreliable. This review demonstrates that gastric ultrasound is a valuable tool for evaluating gastric content.
