Introduction:
Postoperative pain management is crucial for patient recovery with Quadratus Lumborum Block (QLB) and Transversus Abdominis Plane Block (TAPB) emerging as potential techniques. We aimed to compare the analgesic efficacy of QLB and TAPB in patients undergoing inguinal hernia repair.
Methods:
We performed a systematic review of Cochrane, EMBASE, and MEDLINE databases to identify randomized controlled trials comparing QLB and TAPB in patients undergoing inguinal hernia repair. Outcomes included postoperative pain and opioid consumption. Statistical analysis was performed using RevMan 5.4. The review protocol was registered at PROSPERO (CRD42023445513).
Results:
We included five RCTs encompassing 255 patients. QLB was associated with a significant decrease in postoperative pain (MD -0.45; 95% CI -0.75 to -0.14; and p = 0.004; I2 = 94%). However, we found no difference in 24-h opioid consumption between QLB and TAPB groups.
Conclusion:
QLB may offer superior pain reduction. However, its effect on opioid consumption remains unclear.
