Summary

This is a clinical trial using an up-and-down sequential design, aiming to investigate the median effective dose (ED50) and 95% effective dose (ED95) of oliceridine for inhibiting hyperdynamic responses induced by tracheal intubation during general anesthesia induction. The study will enroll patients undergoing elective tracheal intubation under general anesthesia, stratified into young (18-65 years) and elderly (≥65 years) groups. By dynamically adjusting oliceridine doses, the optimal induction dose in different age groups will be evaluated to provide reference for rational clinical medication.

Conditions

  • Oliceridine

Interventions

DRUG

Oliceridine Injection

Adult participants receive a single IV bolus of oliceridine (initial dose 45 µg/kg for ages 18-65 y or 40 µg/kg for ≥65 y). Two minutes later, propofol 2 mg/kg IV is administered. Upon loss of consciousness (MOAA/S ≤ 1), rocuronium 0.6 mg/kg IV is given. Direct laryngoscopic tracheal intubation is performed after full muscle relaxation. Blood pressure and heart rate are recorded at baseline, 2 min post-oliceridine, immediately pre-intubation, and for 3 min post-intubation. A "positive" hemodynamic response is defined as ≥ 20% increase in MAP or HR, HR ≥ 120 bpm, or SBP ≥ 180 mmHg. Subsequent oliceridine doses are adjusted ± 3 µg/kg based on the prior patient's response until seven response crossovers are observed, allowing estimation of ED₅₀ and ED₉₅.
