Observational Study
Determining residual gastric volume in healthy children using ultrasound.
Fasting guidelines for children recommend restricting clear fluids for one or two hours before a procedure to reduce pulmonary aspiration. Gastric volumes < 1.5 mL·kg-1 do not seem to present an increased risk of pulmonary aspiration. Our aim was to quantify the time to achieve a gastric volume < 1.5 mL·kg-1 after clear fluid ingestion in children. ⋯ Our results show that total gastric fluid volume was < 1.5 mL·kg-1 after 60 min, suggesting that current fasting guidelines for children could be liberalized.

Multicenter Study
Association between preoperative cardiac risk assessment and health care costs in major noncardiac surgery: a multicentre health economic analysis.
Patients with impaired functional capacity who undergo major surgery are at increased risk of postoperative morbidity including complications and increased length of stay. These outcomes have been associated with increased hospital and health system costs. We aimed to assess whether common preoperative risk indices are associated with postoperative cost. ⋯ In patients undergoing major noncardiac surgery, common measures of functional capacity are not consistently associated with total postoperative cost. Until further data exist that differ from this analysis, clinicians and health care funders should not assume that preoperative measures of cardiac risk are associated with annual health care or hospital costs for such surgeries.

Glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1RAs) have become increasingly popular as both diabetic and weight loss therapies. One effect of this class of medication is delayed gastric emptying, which may impact the risk of aspiration during anesthesia delivery. ⋯ This study provides preliminary evidence that GLP-1RAs may affect gastric emptying and residual gastric contents following an overnight fast and two hours after clear liquids, which may have implications for aspiration risk during anesthetic care.

Observational Study
The correlation between patient satiety sensation and total gastric fluid volume: a prospective observational study.
Surgical patients are asked to adhere to preoperative fasting guidelines to minimize gastric contents. Large fluid volumes or solid content can still be present as shown with gastric ultrasound. It has been suggested that additional rating of patients' satiety, measured as the feeling of hunger and thirst, could help clinicians to better judge emptying of the stomach. ⋯ ClinicalTrials.gov (NCT04884373); registered 13 May 2021.
