Abstract: After a quadratus lumborum (QL) block, the course of QL plane catheter is unpredictable. This case series discusses the course and fate of trans-muscular QL catheters by following and discussing the contrast spread through the fascial planes. Intrao-peratively, the catheters were tracked by the surgeons and were checked for integrity of anterior thoracolumbar fascia (ATLF) by injecting sterile 0.9% saline. The ATLF was intact upon injection and there was cephalad and medial saline spread with slight bulging of… Show more

“…emphasised that the spread of LA is governed by multiple factors such as the path of least resistance by LA, speed of injection, catheter tip, and volume of LA injection in QLB and hence dermatomes involved may be unpredictable. [ 26 ] The present study failed to demonstrate a greater difference in 24 h tramadol consumption due to single shot block with a lower volume of 20 ml of LA for anterior QL block and the continuity of analgesic benefit of spinal anaesthesia in the initial post-operative period.…”

“…9) [17,18,19]. Both single shot and continuous QLB are practiced, however, at this point of time, there is no scientific evidence that establishes the superiority of one approach over the other, nor is the fate of a catheter placed in the TLF conclusively determined [20,21]. Given the proximity of the lumbar plexus and the continuation of the anterior TLF caudally with the fascia iliaca, blockade of lumbar plexus is likely, and clinical reports suggest QL block for analgesia following hip surgery.…”

“…Contrast studies have demonstrated the spread of injectate after QLB to paravertebral space and anterior epidural space, which is possibly responsible for the analgesia provided. [ 4 ] Earlier Wikner et al . had described a report in which a patient undergoing laparoscopic excision of endometriosis had motor weakness following QLB.…”
