ED90 of Tegileridine for Suppressing Hemodynamic Response to Tracheal Intubation: A Biased Coin Up-and-Down Trial
China108 participantsStarted 2026-09-01
Plain-language summary
General anesthesia tracheal intubation causes sympathetic activation and hemodynamic stress response, which increases perioperative cardiovascular risk, especially in elderly subjects. Tegileridine fumarate is a novel μ-opioid receptor G protein-biased agonist. However, the optimal dose of tegileridine to suppress intubation-induced hemodynamic fluctuations during anesthesia induction remains unclear.
This is an open-label, single-center, age-stratified biased coin up-and-down sequential trial. Subjects undergoing elective surgery requiring tracheal intubation will be divided into young adult group (18-64 years) and elderly group (≥65 years). The primary objective is to determine the ED90 of intravenous tegileridine for inhibiting hemodynamic response to tracheal intubation using centered isotonic regression. Secondary outcomes include induction-related adverse events, serial hemodynamic parameters and sedation scale. This study will provide evidence for rational dosing of tegileridine in clinical anesthesia induction.

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