Ultrasound Assessment of Gastric Residual Volume in Obese Patients

Egypt100 participantsStarted 2019-10-15

Plain-language summary

Gastric emptying is a major risk factor for aspiration of gastric contents.Aspiration into the lungs represents a fatal complication that can occur during anesthesia. Not only gastric emptying importance to anesthetists is related to aspiration but also it is important to determine the systemic availability of substances given through the mouth. Delayed gastric emptying represents a major danger as it causes nausea and vomiting and prevents a return to oral feeding. Lastly it may cause morbidity and mortality. Both humoral and neural influences have their impact on emptying. Volume and composition of gastric food act as major determinants for the rate of gastric emptying. The effect of body weight on gastric emptying are inconsistent. ASA fasting guidelines application represents the primary method to avoid aspiration as it ensures that stomach is empty before induction of anesthesia. These guidelines cannot be applied on all cases as in urgent or emergent situations or in morbidities associated with delayed gastric emptying. Ultrasound can be used perioperatively to asses gastric content and volume at bedside.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
