Ultrasound guided continuous transmuscular quadratus lumborum analgesia for open renal surgery: A case series

Ultrasound guided erector spinae plane block versus quadratus lumborum block for postoperative analgesia in patient undergoing open nephrectomy: A randomized controlled study

“…Intraoperative heart rate (HR) among the studied groups. Group C: Control group, Group QLB: Quadratus lumborum block, Group ESPB: Erector spinae plane block *Statistical significant difference between control group and two interventional groups studies revealed some limitations as possible sparing of the upper thoracic dermatomes [26], unexpected motor weakness of lower limb due to possibly involvement of lumbar plexus [27] and also may be complicated with direct needle trauma of the kidney and risks of retroperitoneal spread of hematoma [28]. The ESPB can be used to provide regional analgesia for a wide range of surgical procedures in the anterior, posterior, and lateral thoracic and abdominal regions [7,8] and also to treat acute and chronic pain syndromes [5].…”

“…As a consequence, sensory blockage levels in both groups outweigh the likelihood of having adequate analgesic effects after nephrectomy because the flank incision is fully blocked. However, Warusawitharana et al, stated in their case series study the possibility of sparing of upper thoracic dermatomes with the transmuscular quadratus lumborum block used for analgesia for open renal surgery [26], which could decrease its efficacy as an upper abdominal surgery analgesic. Chin et al, on the other hand, observed radiologically cadaveric distribution of ESPB local anesthetic extending from the injection site to 3 or 4 levels cranially and caudally [6] therefore, we opted to apply a single-level injection at T7 level to block both supra-umbilical and infra-umbilical dermatomes that are inconsistent with the dermatomes affected by open nehprectomy rendering it as effective alternative analgesic technique in such surgeries.…”

Continuous basal infusion versus programmed intermittent bolus for quadratus lumborum block after laparoscopic colorectal surgery: a randomized-controlled, double-blind study

“…Quadratus lumborum block (QLB) is a newly developed technique which has been shown to produce better analgesia compared with TAPB for patients undergoing cesarean section [3], open hysterectomy [4], laparoscopic surgery [5,6], and lower abdominal surgery [7,8]. Continuous QLB with a catheter(s) has also been reported to provide effective and prolonged analgesia in patients after colorectal surgery [9,10], renal surgery [11][12][13], and liver resection [14]. However, a few studies have focused on the difference in delivery methods including the difference between single shot and continuous infusion for QLB.…”

Ultrasound-guided continuous transmuscular quadratus lumborum block- L4 or L2 level catheter insertion for analgesia in open abdominal surgery: Case series

“…[ 3 4 5 ] There is a general paucity of literature on continuous use of TQL block in adults for major abdominal surgery. [ 6 7 ] We have previously reported TQL block performed at L4 resulting in transient paraesthesia of the leg in one case. [ 6 ] In view of this issue, we performed the same block at L2 level without adverse effect.…”
