About this trial

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 investigational-drug adverse events, serial hemodynamic parameters. This study will provide evidence for rational dosing of tegileridine in clinical anesthesia induction.

Treatments tested in this trial

  • Tegileridine

    Drug

    Intravenous tegileridine administered prior to anesthesia induction. The initial dose and dose adjustment steps are predefined; individual dose will be modified by biased coin up-and-down sequential method to explore ED90 for inhibiting hemodynamic response to tracheal intubation.

Trial outcomes

Primary outcomes

1

ED90 to suppress hemodynamic response of tracheal intubation

Successful suppression of hemodynamic response is defined as a maximum increase in hemodynamic variables ≤20% from baseline within 3 minutes after tracheal intubation. Centered isotonic regression will be used to calculate the ED₉₀ of tegileridine.

Time frame
Within 3 minutes after tracheal intubation

Secondary outcomes

1

Number of subjects with cough during the study drug (tegileridine) administration and observation period.

Number of subjects with cough during the study drug (tegileridine) administration and observation period, with severity graded as: Mild (1-2 episodes), Moderate (3-5 episodes), Severe (\>5 episodes).

Time frame
From the start of tegileridine injection until 2 minutes after completion of injection.

Other outcomes

1

Hypotension

Hypotension is defined as systolic blood pressure \< 90 mmHg or mean arterial pressure (MAP) \< 60 mmHg.

Time frame
From the start of tegileridine injection until 2 minutes after completion of injection.
2

Bradycardia

Bradycardia is defined as heart rate \< 50 beats per minute.

Time frame
From the start of tegileridine injection until 2 minutes after completion of injection.
3

Injection pain

Pain induced by drug injection, assessed immediately after intravenous drug administration.

Time frame
From the start of tegileridine injection until 2 minutes after completion of injection.
4

Chest wall rigidity

Chest wall rigidity is defined as opioid-induced increased tone of thoracic and abdominal muscles leading to reduced chest-wall compliance and difficulty with manual or mechanical ventilation.

Time frame
From the start of tegileridine injection until 2 minutes after completion of injection.
