Peripheral Nerve Blocks Reduce Postoperative Pain After Hip Replacement
“Controlling pain after a hip replacement improves patient comfort and satisfaction.”
Peripheral nerve blocks may reduce postoperative pain and increase patient satisfaction in adults undergoing elective primary hip replacement, according to the results of a systematic review published in Cochrane Database of Systematic Reviews.
To evaluate the benefits and harms of nerve blocks after elective hip replacement, a systematic review of 51 randomized controlled trials (n=2793) was performed. A total of 45 randomized controlled trials were included in the meta-analyses, which compared peripheral nerve block (n=1288) with any other pain management option (n=1203).
Two reported adverse events associated with peripheral nerve blocks included local hematoma and delayed persistent paresis.
The study authors explained that, “[more than] 300,000 total hip replacements are performed each year in the [United States] alone,” and stated further, “Controlling pain after hip replacement improves patient comfort and satisfaction and enables patients to participate in rehabilitation more fully, leading to an earlier return home and reduced demand on resources.” Based on the study results, the authors concluded that, “peripheral nerve blocks may offer advantages,” compared with systemic analgesia.
