Key result
Preoperative ultrasound reveals ~21% of surgical patients exceed high-risk gastric area cutoffs despite standard fasting.
Why the study?
Pulmonary aspiration of gastric contents is a serious perioperative complication, and the efficacy of portable ultrasonography for preoperative gastric content evaluation needed assessment.
Does portable ultrasonography effectively evaluate preoperative gastric contents in surgical patients?
Population
120 patients who underwent surgery
Comparison
None; evaluation of gastric contents by ultrasonography

Does portable ultrasonography effectively evaluate preoperative gastric contents in surgical patients?
Bedside ultrasonography is a useful non-invasive tool for determining gastric content, revealing that a significant proportion of surgical patients may not have an empty stomach despite recommended fasting protocols.
Kaydu et al. (2018) conducted a cross-sectional in Preoperative surgical patients (n=120). Portable ultrasonography was evaluated on Exceeding high-risk stomach antral cutoff cross-sectional area (340 mm2) after fasting for at least 8 hours. Preoperative bedside ultrasonography revealed that 20.8% of surgical patients exceeded the high-risk gastric antral cross-sectional area cutoff despite fasting for at least 8 hours.
