Single injection Quadratus Lumborum block for postoperative analgesia in adult surgical population: A systematic review and meta-analysis

Managing rebound pain after regional anesthesia

“…Rebound pain is a phenomenon that primarily manifests following PNB that provide dense sensory blockade (e.g., brachial plexus [2,7,10], popliteal sciatic [3,9] nerve blocks). Dramatic increases in pain scores and opioid consumption related to block offset are not usually seen in studies of fascial plane blocks such as transversus abdominis plane [59], pectoral nerves [60], erector spinae plane, [61] and quadratus lumborum [62,63] blocks.…”

“…Rebound pain is a phenomenon that primarily manifests following PNB that provide dense sensory blockade (e.g., brachial plexus [ 2 , 7 , 10 ], popliteal sciatic [ 3 , 9 ] nerve blocks). Dramatic increases in pain scores and opioid consumption related to block offset are not usually seen in studies of fascial plane blocks such as transversus abdominis plane [ 59 ], pectoral nerves [ 60 ], erector spinae plane, [ 61 ] and quadratus lumborum [ 62 , 63 ] blocks. This requires further investigation for confirmation, but it may be related to factors that include a degree of visceral contribution to both pain and analgesic effect, an expectation of incomplete analgesic coverage by the block, and routine incorporation of these techniques into a multimodal analgesic regimen [ 64 – 66 ].…”

The indirect benefits of a quadratus lumborum block in urgent laparotomy, hepatic resection, and open aortic surgery

“…In the recent systematic review by Jin et al [2], the authors have focused their work in the postoperative analgesic outcomes, showing the QLB contribution to improve post-operative pain in renal surgery, cesarean section and also in other abdominal, pelvic and hip surgeries despite the quality of evidence is low in these later cases.…”

“…In urgent laparotomy (in patients suffering from peritonitis) a single-shot QLB is certainly an option, as it provides significant somatic and visceral analgesia up to 24 h post-operatively (at least) [2], which may diminish the need of a continuous technique and the subsequent risk of catheter colonization. In deed, single-shot QLB has been associated to a reduction in pain and opioid consumption up to 48 h after surgery [1].…”

Continuous trans-muscular quadratus lumborum block for patient with postscoliosis correction undergoing open adrenalectomy - A case report

“…Single-injection QLB has been found to be effective in patients undergoing cesarean sections and renal and hip surgeries. [ 2 ] We decided to perform TMQLB because of the understanding that previous spine instrumentation would still preserve integrity and sonoanatomy of relevant structures such as QLM and PMm. [ 3 ] To the best of our knowledge, there are no case reports describing the use of QLB in patients with previous spine instrumentation.…”
