Effect of Transcutaneous Electrical Nerve Stimulation Based on Wrist-ankle Acupuncture Theory on EC50 of Remifentanil Inhibiting Responses to Tracheal Intubation Under General Anesthesia
China60 participantsStarted 2025-02-06
Plain-language summary
During endotracheal tube insertion under general anesthesia, sympathetic nerve activity increases, which leads to increased heart rate, increased blood pressure, and increased catecholamine levels in the blood. It is important for patients to maintain hemodynamic stability during anesthesia induction and ultimately mitigate the cardiovascular stress response associated with tracheal intubation.
Transcutaneous Electrical Nerve Stimulation based on Wrist-Ankle Acupuncture theory (TENS-WAA) is a non-invasive pain treatment method, It has the advantages of easy wearing, concentrated treatment site, safe treatment and needle-free. To date, due to the lack of large-scale clinical use of TENS-WAA, only a few studies have reported the use of TENS-WAA for postoperative pain rehabilitation, especially for perioperative pain management. The aim of this study is to evaluate the median effective dose (ED50) of TENS-WAA for remifentanil inhibiting responses to tracheal intubation under general anesthesia, and to provide a reliable basis for its clinical promotion.

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.
What they're measuring
1
the half maximum effective concentration (EC50) of remifentanil
Timeframe: The remifentanil concentration was recorded for 2 minutes after successful tracheal intubation.
