Abstract
Abstract
Study objective
To evaluate the efficacy of ultrasound-guided single-shot quadratus lumborum block (QLB) for postoperative analgesia in adults following total hip arthroplasty (THA).
Design
Systematic review and meta-analysis.
Setting
Perioperative period.
Patients
Adult patients undergoing THA.
Methods
Studies were identified by performing searches in the following electronic databases, PubMed (Medline), Cochrane Central Registry of Trials (CENTRAL), and Google Scholar. We sought studies in adult patients undergoing THA, comparing QLB with a control group (no block, sham block or any other ultrasound guided regional nerve blocks). A total of 774 patients from 10 studies (7 randomized controlled, one controlled clinical and two retrospective study) were included in this meta-analysis.
Main results
The 24 hour opioid consumption was similar in both the groups (WMD −4.09; 95% CI [−9.00, 0.83]; P = 0.10; I2 = 95%). The pain scores at rest at 24 hours was significantly less in QLB group (WMD −0.62; 95% CI [−1.15, −0.10]; P = 0.02; I2 = 75%). The difference in pain scores was however not clinically significant. The pain scores on movement at 24 hours, time to first analgesic request, and time to discharge from hospital were similar in both the groups.
Conclusions
QLB as part of multimodal analgesia did not result in any significant analgesic benefits in patients undergoing hip arthroplasty in terms of either postoperative opioid consumption or pain scores at rest and on movement. Overall, the level of certainty is low. Further, well-designed trials are required to verify the results.
