A significant component of pain experienced after abdominal surgery is related to incision of the abdominal wall and adequate analgesia can be a challenge. As a result, the use of anatomical knowledge to achieve analgesia after abdominal surgery and the evolution of ultrasound and different approaches over time have resulted in a variety of analgesic techniques which are used in current clinical practice. One of the newly described methods of providing truncal blockade after abdominal surgeries is the quadratus lumborum block. The original concept of an ultrasound-guided (USG) quadratus lumborum (QL) block indicated for postoperative pain management (POPM) after abdominal surgery was conceived by Rafael Blanco in 2007 when he described a potential space posterior to the abdominal wall muscles and lateral to the quadratus lumborum muscle where the LA was injected close to the anterolateral border of the QL muscle and superficial to the transversalis fascia(TF) and this point was then modified to be at the posterior border of the quadratus lumborum muscle 4. it was demonstrated that the original QL block will anaesthetize both the lateral and anterior cutaneous branches from Th7 to L1
