• Background: Intravenous (IV) oxycodone has been used at induction to prevent an intubation reaction. The aims of the current study were to calculate the median effective dose (ED50) and the 95% effective dose (ED95) of an IV bolus of oxycodone that blunts the hemodynamic response to tracheal intubation with propofol according to gender and to observe the adverse events of induction-dose oxycodone. Methods: Adult patients who required general anesthesia and tracheal intubation were enrolled. Tracheal intubation was performed using unified TD-C-IV video laryngoscopy and an ordinary common endotracheal tube. Dixon's up-and-down method was used to obtain ED50data for women and men separately. The initial dose of oxycodone was 0.2 mg/kg for women and 0.3 mg/kg for men (step size was 0.01 mg/kg). Next, a dose-response curve from the probit analysis was generated to determine the ED50and ED95to blunt the intubation reaction in female and male patients. Adverse events following oxycodone injection were observed for 5 min before propofol injection. Results: Sixty-three patients were analyzed, including 29 females and 34 males. According to the probit analysis, the ED50 and ED95of oxycodone required to blunt the intubation reaction in women were 0.254 mg/kg (95% confidence interval [CI], 0.220-0.328 mg/kg) and 0.357 mg/kg (95% CI, 0.297-2.563 mg/kg), respectively. In men, the ED50 and ED95were 0.324 mg/kg (95% CI, 0.274-0.381 mg/kg) and 0.454 mg/kg (95% CI, 0.384-2.862 mg/kg), respectively. Men required 28% more oxycodone than women for induction (P < 0.01). The most common adverse events were dizziness (87.3%), vertigo (66.7%), sedation (74.6%), and respiratory depression (66.7%). Conclusions: Oxycodone can be used for induction to prevent intubation reactions. Gender affected the ED50and ED95of oxycodone for blunting the tracheal intubation reaction.
