Abstract
Background
Pain management after total hip arthroplasty (THA) varies and has been widely studied in recent years. Gabapentin as a third-generation antiepileptic drug that selectively affects the nociceptive process has been used for pain relief after THA. This meta-analysis was conducted to examine the efficacy of gabapentin in THA.
Methods
An electronic-based search was conducted using the following databases: PubMed, EMBASE, Ovid MEDLINE, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL). Randomised controlled trials (RCTs) involving gabapentin and a placebo for THA were included. The meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.
Results
Five trials met the inclusion criteria. The cumulative narcotic consumption and the visual analogue scale (VAS) scores at 24 and 48 h postoperatively were used for postoperative pain assessment. There was a significant decrease in morphine consumption at 24 h (P = 0.00). Compared with the control group, the VAS score (at rest) at 48 h was less in the gabapentin group (P = 0.00).
Conclusion
The administration of gabapentin is effective in decreasing postoperative narcotic consumption and the VAS score.
