Comparison of the analgesic effects of ultrasound-guided erector spinae plane block and quadratus lumborum block: a systematic review and meta-analysis.

ABSTRACT:

Background

Erector spinae plane block (ESPB) and quadratus lumborum block (QLB) are commonly used for perioperative analgesia in various surgeries. An increasing number of randomized controlled trials (RCTs) have compared the analgesic effect and safety of ESPB with those of QLB, but the conclusions are controversial. This study was designed to identify whether ultrasound-guided ESPB was better than the QLB for postoperative analgesia.

Methods

To identify RCTs comparing ESPB with QLB for postoperative analgesia, we searched PubMed, Embase, the Cochrane Library, and Web of Science. The primary outcome was postoperative analgesic consumption over 24 h. The secondary outcomes included the time to the first analgesic request, postoperative resting pain scores, block performance
