Effect of Head Turn on Double-Lumen Tube Alignment
Taiwan35 participantsStarted 2024-04-10
Plain-language summary
This study evaluated how simple external airway maneuvers affect the alignment of the left main bronchus during placement of a left-sided double-lumen endotracheal tube. Adults undergoing elective thoracic surgery requiring one-lung ventilation were enrolled.
During double-lumen tube placement, a fiberoptic bronchoscope was used to continuously view the airway. Each participant underwent three sequential maneuvers: rightward displacement of the trachea, turning the head 45 degrees to the right, and turning the head 45 degrees to the left. The investigators measured how far the opening of the left main bronchus moved on the bronchoscopic image and whether it crossed the center of the image.
The purpose of the study was to determine how these maneuvers change airway alignment and whether they may help guide a left-sided double-lumen tube toward the left main bronchus.

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?
