Figure 1: Ultrasound-guided subcostal anterior QL block. (a) Schematic representation of the ultrasound-guided anterior subcostal approach to the QL nerve catheter insertion. (b) Ultrasound image showing the spread of local anaesthetic. The white arrow represents the needle path. LD = latissimus dorsi, ES = erector spinae, QL = quadratus lumborum, PM = psoas muscle, LA = local anaesthetic
