PURPOSE: To compare the efficacy of a lower dose background infusion of oxycodone for patient-controlled intravenous analgesia (PCIA) with the conventional dose, following intercostal nerve block, for the management of postoperative pain in patients undergoing thoracoscopic lobectomy for lung cancer.
PATIENTS AND METHODS: This was a prospective, single-center, randomized, parallel-group, double-blind, controlled clinical trial. In total, 155 patients scheduled for elective radical lobectomy via video-assisted thoracoscopy were recruited from December 2018 to July 2019, of whom 140 were ultimately included in the study population. Patients were randomized to receive either oxycodone 0.25 mg/h (low-dose group, n=70) or oxycodone 0.5 mg/h (control group, n=70) as a background infusion for PCIA, following ropivacaine intercostal nerve block, for postoperative pain management. The primary endpoints were rest and dynamic visual analogue scale (VAS) scores within 72 h of the operation. The secondary endpoints were patient satisfaction scores, consumption of postoperative analgesics, times of patient-controlled analgesia (PCA), and adverse events.
RESULTS: All 140 enrolled patients completed the study requirements and were included in the final analysis. The rest and dynamic VAS scores at 4 h, 24 h, 48 h, and 72 h postoperative were comparable between the low-dose group and the control group (P>0.05). However, the low-dose group had statistically significantly higher patient satisfaction scores (P<0.001) and lower postoperative analgesic consumption (P<0.001) as well as lower incidence of nausea and vomiting (P<0.05). The times of PCA was not statistically significantly different between the two groups, and no serious adverse events occurred in either group (P>0.05).
CONCLUSION: A low-dose background infusion of oxycodone for postoperative PCIA can achieve a comparable analgesic effect to the conventional dose after thoracoscopic lobectomy for lung cancer. Furthermore, the low-dose regimen was associated with reduced consumption of oxycodone and increased patient satisfaction.
