Brief Summary
Sufentanil is the most widely used opioid analgesic for general anaesthesia induction; however, rapid intravenous bolus injection frequently triggers sufentanil-induced cough (SIC). In high-risk patients, SIC can cause abrupt elevation of intracranial and intraocular pressure and severe haemodynamic instability, posing a meaningful safety risk during the induction period. Oliceridine, the first G protein-biased μ-opioid receptor agonist approved by the Food and Drug Administration in 2020, provides analgesia through μ-receptor activation while substantially reducing β-arrestin-2 recruitment. This biased signalling profile is hypothesised to raise the excitation threshold of airway C-fibres and thereby reduce the incidence of cough. This prospective, single-centre, randomised, double-blind, parallel-group controlled trial directly compares oliceridine with sufentanil for general anaesthesia induction with respect to cough incidence, cough severity, haemodynamic responses, and perioperative safety, with the aim of providing evidence-based guidance for opioid selection during induction.

Outcome Measures
Primary Outcomes (1)
Incidence of Cough
The proportion of participants who cough at least once within 2 minutes of study drug injection. Cough is defined as a sudden, forceful expiratory effort occurring after drug administration and assessed by direct observation.
Within 2 minutes of study drug injection
Secondary Outcomes (4)
Cough Severity
Within 2 minutes of study drug injection.
Heart rate
From entry into the operating room to 10 minutes after administration of the study drug.
Blood pressure
From entry into the operating room to 10 minutes after administration of the study drug.
Opioid-related Adverse Events
From study drug injection to completion of tracheal intubation, approximately 10 minutes.
Study Arms (2)
Oliceridine Group
EXPERIMENTALParticipants will receive intravenous oliceridine 0.05 mg/kg (elderly patients aged ≥65 years) or 0.06 mg/kg (younger patients aged 18-64 years), administered as a 2-second bolus injection. Cough will be observed for 2 minutes after injection, after which anaesthesia induction will be completed with propofol and rocuronium , followed by tracheal intubation.
Sufentanil Group
ACTIVE COMPARATORParticipants will receive intravenous sufentanil 0.25 μg/kg (elderly patients aged ≥65 years) or 0.3 μg/kg (younger patients aged 18-64 years), administered as a 2-second bolus injection. Cough will be observed for 2 minutes after injection, after which anaesthesia induction will be completed with propofol and rocuronium , followed by tracheal intubation.
Interventions
Oliceridine is administered as a single intravenous bolus over 2 seconds at a dose of 0.05 mg/kg in elderly patients (aged ≥65 years) or 0.06 mg/kg in younger patients (aged 18-64 years), immediately before propofol and rocuronium for anaesthesia induction.

Eligibility Criteria
You may qualify if:
- Aged 18 to 99 years.
- American Society of Anesthesiologists (ASA) physical status classification I, II, or III.
- Body mass index (BMI) between 18.5 and 28.0 kg/m².
- Scheduled for elective surgery under general anaesthesia.
- Able to understand the study procedures and provide written informed consent.
You may not qualify if:
- Preoperative upper respiratory tract infection symptoms (e.g., cough, expectoration, or fever) or a history of bronchial asthma or other conditions associated with increased airway reactivity.
- Severe cardiovascular disease (e.g., uncontrolled hypertension, recent myocardial infarction, or serious arrhythmia) or hepatic or renal dysfunction.
- Long-term opioid use, defined as continuous opioid use for more than 2 weeks within the 3 months prior to surgery.
- Known hypersensitivity to any study drug or anaesthetic agent used in this protocol.
- Anticipated difficult airway requiring awake intubation.
- Pregnancy or breastfeeding.
