Quadratus Lumborum Block

Brief summary

* Primary outcome: to compare the efficacy of Anterior subcostal versus Posterior approach in ultrasound guided Quadratus Lumborum Block. * Secondary outcome: to evaluate the efficacy of Quadratus Lumborum Block in the control of postoperative pain in patients undergoing Nephrectomy surgery, hemodynamics, any complications and patients' satisfaction..

Detailed description

A variant of the ultrasound-guided transversus abdominis plane (TAP) block was first described in an abstract, in which local anesthetic injection occurs at the point where the internal oblique and transversus abdominis muscles taper off and adjoin the lateral border of quadratus lumborum (QL) muscle. Currently, the QL block is performed as one of the perioperative pain management procedures for all generations (pediatrics, pregnant, and adult) undergoing abdominal surgery. However, there is large disagreement regarding the best approach for administering the block because of unclear mechanisms responsible for the effects and complicated nomenclature system. Nephrectomy for patients with renal cell carcinoma (RCC) was first described in 1969. Surgical treatment varies with the pathology. Simple nephrectomy is the preferred option for those with non-neoplastic disease (e.g. trauma, non-functioning kidney with chronic infection) with radical nephrectomy being preferred in those with neoplastic disease. Radical nephrectomy implies resection of the whole of Gerota's fascia, including the perinephric fat, lymphatics, and the ipsilateral adrenal gland. Here the investigators are going to compare the Anterior (subcostal) approach to the Posterior approach to determine their level of spread and their value in controlling postoperative pain in patients scheduled for Nephrectomy surgery.
