Abstract
Purpose
The purpose of this meta-analysis was to compare the efficacy and safety of single-dose intra-articular bupivacaine plus morphine versus bupivacaine alone for pain management following arthroscopic knee surgery.
Method
A comprehensive literature search was conducted to identify randomized controlled trials that used single-dose intra-articular bupivacaine plus morphine and bupivacaine alone for post-operative pain, using MEDLINE (1966–2014), Cochrane Library and EMBASE databases. The weighted mean difference (WMD), relative risk (RR) and their corresponding 95 % confidence intervals (CIs) were calculated using RevMan statistical software.
Result
A total of twenty-nine trials (n = 1167) were included. The post-operative visual analog scale (VAS) pain score of the bupivacaine plus morphine group compared with the bupivacaine alone group was significantly lower (WMD −1.15, 95 % CI −1.67 to −0.63, p < 0.0001). As far as safety, there was no significant difference in side effects between the two groups (RR 1.10, 95 % CI 0.59–2.04, n.s.). Sensitivity analyses suggested that the results of these two primary outcomes were stable and reliable. However, the current evidence did not suggest a superior effect with respect to the time to first analgesic request (WMD 51.33, 95 % CI −110.99 to 213.65, n.s.) and the number of patients requiring supplementary analgesia (RR 1.13, 95 % CI 0.92–1.39, n.s.).
Conclusions
On the basis of the currently available literature, this study is the first to suggest that single-dose intra-articular bupivacaine plus morphine was shown to be significantly better than bupivacaine alone at relieving post-operative pain after arthroscopic knee surgery without increasing the short-term side effects. Routine use of single-dose intra-articular bupivacaine plus morphine is an effective way for pain management after arthroscopic knee surgery.
