Continuous Endotracheal Tube Cuff Pressure Monitoring and Postoperative Airway Complications in Laparoscopic Surgery

Turkey (Türkiye)95 participantsStarted 2024-05-10

Plain-language summary

This prospective randomized controlled study evaluated the effects of different endotracheal tube cuff pressure monitoring strategies on postoperative airway complications in patients undergoing elective laparoscopic abdominal surgery under general anesthesia. Excessive endotracheal tube cuff pressure may impair tracheal mucosal perfusion and lead to postoperative airway symptoms such as sore throat, cough, dysphagia, hoarseness, and hemoptysis. A total of 95 adult patients (ASA I-II) aged 18-65 years were randomly assigned to one of three groups according to the cuff pressure monitoring technique used during surgery: the cuff-leak technique (control group), intermittent cuff pressure monitoring using a manual manometer every 30 minutes, or continuous cuff pressure monitoring using a pressure transducer connected to the pilot balloon. The primary outcome was the incidence of cuff-related postoperative airway complications at postoperative hours 2 and 24. Secondary outcomes included tracheal mucosal injury assessed by fiberoptic bronchoscopy before extubation and its association with postoperative airway symptoms. The study aimed to determine whether continuous cuff pressure monitoring reduces postoperative airway complications and tracheal mucosal injury compared with intermittent monitoring and the cuff-leak technique.

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.
