Comparison of pain relief between patient-controlled epidural analgesia and patient-controlled intravenous analgesia for patients undergoing spinal fusion surgeries.

Abstract

INTRODUCTION:

This meta-analysis aimed to compare the postoperative analgesic effects of patient-controlled epidural analgesia (PCEA) and patient-controlled intravenous analgesia (PCIA) for patients undergoing spinal fusion surgeries.

METHOD:

Relevant articles were identified using computerized and manual search strategies. Statistical analyses were undertaken by the CMA 2.0 statistical software.

RESULTS:

Nine cohort studies with a total of 436 patients undergoing spinal fusion surgeries were incorporated in the present meta-analysis. There were significant differences between the PCEA and PCIA groups in the visual analogue scale score of patients undergoing spinal fusion [standardized mean difference = 0.27, 95 % confidence interval (95 % CI) = 0.070-0.470, P = 0.008]. However, no obvious difference was observed in the rate of side effects between the PCIA and PCEA groups (side effects: odds ratio = 0.957, 95 % CI = 0.536-1.708, P = 0.882).

CONCLUSION:

Our findings suggested that PCEA may be more effective in relieving pain than PCIA for patients undergoing spinal fusion surgeries.
