BackgroundSurgery for bone malignancy is associated with intense postoperative pain. Patient-controlled epidural analgesia (PCEA) and intravenous patient-controlled analgesia (IV-PCA) are used currently for postoperative pain control.MethodsThe degree of pain control after resection of bone malignancy under combined general and epidural anesthesia followed postoperatively by prospectively randomized PCEA (ropivacaine 3.2 mg + fentanyl 8 microg/dose) or IV-PCA (morphine 2 mg/dose) (n = 35/group) was assessed. Postoperative analgesia delivery continued for up to 96 h; intramuscular rescue with diclofenac 75 mg was also available.ResultsThe mean hourly pain score among the PCEA patients was 3.0 +/- 0.9, compared with 4. 7 +/- 0.6 (P < .01) among the IV-PCA patients. All mean hourly pain scores in the PCEA patients, except for the first 2 hours of treatment, were less than 4/10, but they were higher in the IV-PCA patients. The demand for diclofenac was 2 times (n = 10) lower for the PCEA patients, compared with their IV counterparts (n = 20, P < .01); the same difference applied to the overall side effects (n = 15 vs n = 30, P < .01). Self-rated wakefulness and feelings of well-being were better in the PCEA patients.ConclusionsPostoperative ropivacaine + fentanyl via PCEA reduces pain better and affords better subjective feelings than IV morphine via PCA after resection of bone malignancy carried out under combined general and epidural anesthesia.
