Efficacy of oxycodone in intravenous patient-controlled analgesia with different infusion modes after laparoscopic radical surgery of cervical cancer a prospective, randomized, double-blind study

The aim of this study was to compare the analgesic and adverse effects of oxycodone with 3 different infusion modes on postoperative pain after laparoscopic radical surgery of cervical cancer. Ninety patients undergoing laparoscopic radical surgery of cervical cancer were randomly divided into 3 groups: Group A (continuous infusion with 0.01 mg/kg/h and a bolus dose with 0.03 mg/kg), Group B (a bolus dose with 0.03 mg/kg) and Group C (PCA was administered as a time-scheduled decremental continuous infusion based on lean body mass). A blinded observer recorded Visual Analogue Scale (VAS), Ramsay sedation score (RSS), infused cumulative dose of oxycodone and side effects at 1, 6, 12, 24, and 48 hours postoperatively, and satisfaction during the postoperative 48 hours. There were significant differences in the VAS pain score when resting or coughing among 3 groups at 1, 6 and 48 hours postoperatively (P
