Brief 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.

Outcome Measures
Primary Outcomes (2)
ED₉₅ of oliceridine for suppression of tracheal intubation-induced hemodynamic response
95% effective dose (ED₉₅) of oliceridine required to prevent a positive hemodynamic response-defined as ≥ 20% increase in mean arterial pressure or heart rate, heart rate ≥ 120 bpm, or systolic blood pressure ≥ 180 mmHg-within 3 minutes after tracheal intubation during general anesthesia induction, estimated by probit regression analysis of up-and-down sequential dosing data.
From the start of intubation to 3 minutes after the end of intubation
ED₅₀ of oliceridine for suppression of tracheal intubation-induced hemodynamic response
Median effective dose (ED₅₀) of oliceridine required to prevent a positive hemodynamic response-defined as ≥ 20% increase in mean arterial pressure or heart rate, heart rate ≥ 120 bpm, or systolic blood pressure ≥ 180 mmHg-within 3 minutes after tracheal intubation during general anesthesia induction, estimated by probit regression analysis of up-and-down sequential dosing data.
From the start of intubation to 3 minutes after the end of intubation

Study Arms (1)
Oliceridine Up-and-Down Sequential Dose-Finding Arm
EXPERIMENTALIn this single-group, up-and-down sequential design, adult patients receive a single intravenous bolus of oliceridine. * Initial dose: 45 µg/kg for ages 18-65 years; 40 µg/kg for ≥ 65 years * Two minutes later: propofol 2 mg/kg iv * At loss of consciousness (MOAA/S ≤ 1): rocuronium 0.6 mg/kg iv * Direct-laryngoscope tracheal intubation performed upon full muscle relaxation * Hemodynamic variables (BP, HR) recorded at baseline, 2 min post-oliceridine, immediately pre-intubation, and for 3 min post-intubation * A "positive" response (hemodynamic surge) is defined as ≥ 20% increase in MAP or HR, HR ≥ 120 bpm, or SBP ≥ 180 mmHg * Next patient's oliceridine dose is adjusted ± 3 µg/kg according to the preceding patient's response * Sequential dosing continues until seven crossovers are observed, allowing estimation of ED₅₀ and ED₉₅.
Interventions
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.
