BACKGROUND: To determine if oral oxycodone (OOXY) could provide equivalent postoperative analgesia and a similar side-effect profile to i.v. patient-controlled morphine in patients undergoing elective primary total hip replacement (THR) under spinal anaesthesia. METHODS: We studied 110 consecutive patients aged 60-85 yr. After operation, patients were randomly allocated to receive either oral controlled- and immediate-release OOXY or i.v. patient-controlled analgesia (IVPCA) with morphine. Both groups received regular co-analgesia and antiemetics. The primary outcome measures were: (i) postoperative pain at rest and movement and (ii) nausea score recorded 12 hourly. The secondary outcome measures were: (i) time to first mobilization, (ii) total amount of opioid consumed, (iii) number of additional antiemetic doses, and (iv) time to analgesic discontinuation. RESULTS: There were no statistically significant differences in the primary outcome measures of pain at rest and movement (P>0.05, 95% confidence intervals -0.41, +0.96) or nausea score (P>0.5). The secondary outcome measures showed no significant difference in the total amount of opioid consumed (102 vs 63 mg; P>0.05) or time to mobilization (24.45 vs 26.6 h, P=0.2). The number of antiemetic doses required in the first 24 h was significantly lower in the OOXY group (1.1 vs 1.4, P<0.05). The time to analgesic discontinuation was significantly shorter in the OOXY group (50.5 vs 56.6 h, P<0.05). Oral analgesia with OOXY was approximately GBP 10 less expensive per patient than IVPCA. CONCLUSIONS: Oral analgesia with OOXY after THR offers non-inferior analgesia to IVPCA and may offer some logistical and cost advantages.
