Brief Summary
Transversus abdominis plane (TAP) block can be used to provide effective analgesia during the postoperative period following a range of surgeries. TAP block administers local anesthetics between the T6 to L1 spinal nerve roots to stop the nerve signal and to alleviate pain for abdominal procedures 4, 5. The viscera are innervated by the vagal nerve (parasympathetic innervation) and by the splanchnic nerves (sympathetic innervation). The splanchnic nerves carry both visceral efferent and afferent nerve fibers. The sensory (or afferent) part of the splanchnic nerves reach the spinal column at certain spinal segments, It is possible to block central visceral pain conduction with thoracic paravertebral blockade or maybe even with the novel quadratus lumborum (QL) block. The effect of the QL block is believed to result from a spread of LA from its lumbar deposition cranially into the thoracic paravertebral space (TPVS), since Carney et al found traces of contrast agent in the TPVS following application of this block. Hence, the QL block would seem to be able to alleviate both somatic and visceral pain.10 The aim of this study is to compare between quadratus lumborum block, transversus abdominis plane block regarding perioperative analgesia after bladder cancer surgeries by measuring intraoperative hemodynamics, postoperative pain scores and morphine consumption in the first 24 h postoperative.

Study Arms (3)
Control Group
ACTIVE COMPARATORPatients will receive general anesthesia with intravenous opioid
Quadratus lumborum
EXPERIMENTALPatients will receive bilateral quadratus lumborum block
Transversus abdominis plane
EXPERIMENTALPatients will receive bilateral transversus abdominis plane block
Interventions
The patient will be placed in a lateral position with the side to be blocked facing upwards. The ultrasound probe will be properly sterilized and with sterile covers. An 18-20 gauge blunt tipped block needle or a Tuohy needle is advanced under ultrasound guidance on the posterior aspect of the Quadratus Lumborum. The QL muscle is identified with its attachment to the lateral edge of the transverse process of the L4 vertebral body. With the psoas major muscle anteriorly, the erector spinae muscle posteriorly and the QL muscle adherent to the apex of the transverse process, a well recognisable pattern of a shamrock with three leaves can be seen.
The patient will be supine while performing the block and sterilization of the site of the ultrasound and needle entry will be performed. The ultrasound probe is placed in a transverse plane to the lateral abdominal wall in the midaxillary line, between the lower costal margin and iliac crest. The needle is introduced in plane of the ultrasound probe directly under the probe and advanced until it reaches the plane between the internal oblique and transversus abdominis muscles.
