Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include pediatric patients aged 2-60 years undergoing elective surgical procedures requiring general anesthesia.
✕Probably not a fit
Patients undergoing emergency surgical procedures or those with a BMI greater than 24 may not benefit from this study.

What this trial studies
This study aims to evaluate whether novice ultrasound users, such as medical students and inexperienced anesthesiologists, can accurately assess gastric contents using a validated ultrasound technique. The study is divided into two parts: the first part involves training novices on healthy adult volunteers, while the second part focuses on pediatric patients undergoing surgery. Participants will be taught through a 15-minute training video and will perform assessments on a set number of subjects, with their evaluations being recorded for later expert review.
Why it matters
Potential benefit: If successful, this approach could enhance the safety of pediatric anesthesia by improving the assessment of aspiration risk.
How similar studies have gone: While the use of ultrasound for gastric content assessment is established, this specific approach involving novice users is relatively novel and has not been extensively tested.

Million Anesthesia Cases: Preoperative fasting and perioperative outcomes
This project will see if longer pre-surgery fasting harms people having procedures with anesthesia by looking at symptoms like hunger and thirst, physiologic changes such as low blood pressure and blood sugar shifts, and risks like aspiration and nausea.

Fasting options before procedures for people taking once-weekly GLP-1 medicines.
This trial will test whether a 24-hour clear liquid diet versus standard fasting reduces leftover stomach contents in adults who take once-weekly GLP-1 receptor agonists.
