ABSTRACT

【Objective】 To compare the efficacy and safety of oxycodone and sufentanil in transition analgesia after radical surgery of cervical cancer under general anesthesia. 【Methods】 A randomized, double-blind study was conducted. We randomly divided 68 patients on radical surgery of cervical cancer under general anesthesia into two groups Group S (sufentanil in transition analgesia) (n=35) and Group O (oxycodone in transition analgesia) (n=33). Patients in Group S received sufentanil (0.1 μg/kg for endoscopy procedures or 0.15 μg/kg for laparotomy procedures), whereas patients in Group O received oxycodone (0.1 mg/kg for endoscopy procedures or 0.15 mg/kg for laparotomy procedures) 30 min before the end of operation as transition analgesia. We recorded the time of consciousness recovery and extubation, RSS restlessness score, the number of cough times, Ramsay score, Numerical Rating Scale (NRS) at rest in extubation immediately (T0), 30 min after extubation (T1), 1 h after extubation (T2), 2 h after extubation (T3), 4 h after extubation (T4), 12 h after surgery (T5), 24 h after surgery (T6), and the incidence of adverse complications within 24 h after operation. 【Results】 Compared with those in Group S, patients in Group O showed shorter time of consciousness recovery (4.28±3.35 vs. 5.53±2.25, P=0.027), shorter time of extubation (5.92±3.67 vs. 8.09±2.49, P=0.001), lower RSS restlessness score (0.38±0.49 vs. 0.83±0.63, P<0.001), smaller number of cough times (0.96±0.78 vs. 1.34±0.93, P=0.026), lower Ramsay score (2.3±0.58 vs. 2.63±0.85, P=0.017), and lower NRS score at rest in T3 and T4 (2.64±0.63 vs. 3.14±0.66; 2.86±0.81 vs. 3.69±0.75) (P<0.001). The incidence of nausea and vomiting was lower in Group O than in Group S (9.09% vs. 20%; 3.03% vs. 11.43%). 【Conclusion】 Both oxycodone and sufentanil provide adequate pain relief in transitional analgesia after radical surgery of cervical cancer under general anesthesia. However, oxycodone shows longer analgesia, faster recovery, and a lower incidence of side effects than sufentanil.
