Introduction: Emergency surgery patients have a risk of full stomach that is an important factor of perioperative pulmonary aspiration. The aim of this study are to assess gastric content and volume in emergency surgery patients by using scanning protocol of ultrasound, determine the prevalence and risk factors associated with full stomach. Methods: This study was a prospective descriptive study. One hundred and fifty patients who were going to have emergency operation were assessed gastric content and volume by using ultrasound in supine and right lateral decubitus position. Results: There were 70 patients (46.6%) with full stomach. Solid contents were found in 63 patients. Clear fluid content volume more than 1.5 ml/kg were found in 7 patients. The risk factor of full stomach was severe pain (Odds Ratios =5.12, 95% CI = 1.61, 16.22). There were not statistically different of ultrasound assessment time between emptying stomach group and full stomach group and the procedure time was less than 1 minute. The result of gastric assessment affected anesthetic management in 11 patients (7.33%). Conclusion: Gastric assessment by using ultrasound can identify a full stomach condition in emergency patients and not take time to do this procedure. The result of gastric assessment can help for anesthetic planning
