替格列定与舒芬太尼作为全麻诱导前用药的咳嗽反应比较

Using a computer-generated randomized number table, patients were divided into two groups: the experimental group receiving Tiliglitidine (T group) at 20-50ug/kg, and the control group receiving Sufentanil (S group) at 0.2-0.4 μg/kg. After patients arrived in the operating room, routine monitoring including non-invasive blood pressure, electrocardiogram, and oxygen saturation was performed, and intravenous access was established. Patients were oxygenated and given the study drug before anesthesia induction. No other drugs were administered to the patients before giving the study drug. During anesthesia induction, patients received intravenous injection of Tiliglitide or Sufentanil according to their group. The severity of coughing was graded based on the number of coughing episodes: graded by the number and duration of coughs: Grade I, no cough, breathing regular; Grade II, a single mild cough; Grade III, multiple coughs, lasting less than 15 seconds; Grade IV, continuous coughs, lasting more than 15 seconds.

This study was single-blind，the attending anesthesiologist could not be blinded to group allocation. However, the investigator who assessed cough, the patients, the intraoperative data recording nurse, the data collectors, and the statistician were all blinded.
