ABSTRACT
Objective To compare the effects of oxycodone hydrochloride injection versus sufentanil for postoperative analgesia in patients undergoing laparoscopic cholecystectomy (LC) operation. Methods Sixty patients of both sexes , aged 18-65 yr , weighing 46-85 kg , scheduled for LC operation , were randomly divided into 2 groups (n = 30). Patient-controlled intravenous analgesia (PCIA) pump (oxycodone hydrochloride injection 20 mg or sufentanil 100 μg with physiological saline to 100 ml ) was used for postoperative analgesia five minutes before the end of operation. The first dose and bolus dose were both 5 ml , background infusion was 2 ml/h,lockout interval was 5 minute. The NRS score of rest and during movement at 1 ,6 and 24 h after operation,total oxycodone or sufentanil consumption in 24 h, requirement for rescue analgesic, the level of patient′s satisfaction , the adverse events were recorded. Results There was no significant difference in the NRS scores at rest and during movement , total oxycodone or sufentanil consumption in 24 h and postoperative nausea and vomiting (PONV) between the two groups. The patient’s satisfaction were significantly higher (P < 0.05), and the incidence of dizziness were significantly lower (P = 0.026) in group Q than in group S. Both groups were no requirement for rescue analgesic , no sleepiness , no itch , no retention of urine and other adverse reaction. Conclusion PCIA with oxycodone hydrochloride injection is safe and effective in reducing pain after LC operation, however the incidence of dizziness is lower and the level of patient’s satisfaction is higher with oxycodone hydrochloride than with sufentanil.
