Postoperative Cognitive Function After Different Anesthetic Techniques in Obese Patients
Turkey (Türkiye)90 participantsStarted 2023-01-10
Plain-language summary
Obese patients are at increased risk of postoperative cognitive dysfunction (POCD). The effects of different anesthetic techniques on postoperative cognitive function remain controversial. This prospective randomized study aimed to compare the effects of low-flow sevoflurane anesthesia, normal-flow sevoflurane anesthesia, and total intravenous anesthesia (TIVA) on postoperative cognitive function and recovery characteristics in obese patients undergoing elective laparoscopic abdominal surgery. Cognitive function was assessed using the Mini-Mental State Examination (MMSE) before surgery, at postoperative 30 minutes, and on postoperative day 3.

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?

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?
