Comparison of QLB Block and TAP Block in Morbid Obese Patients

The transversus abdominis plane (TAP) block was introduced as a landmark-guided technique via the triangle of Petit to achieve a field block. It involves the injection of a local anesthetic solution into a plane between the internal oblique muscle and transversus abdominis muscle.

"Quadratus lumborum block is a block of the posterior abdominal wall, interfascial plane block, which is performed exclusively under ultrasound guidance. It was described as a variant of the TAP block."
