Summary

Severe perioperative pain experienced after surgical procedures performed by flank incision is mainly related to incision of many muscles. Postoperative pain affects patient comfort, satisfaction, prolongs the duration of hospital stay and increases post-procedure complications. This study is designed to compare the success rate of Unilateral Ultrasound Guided Transmuscular Quadratus Lumborum Block with Unilateral posterior Ultrasound Guided TransversusAbdominus Plane block in providing perioperative analgesia in Patients undergoing Flank Incision surgeries in the Urosurgery Theater at KasrAlainy University Hospitals.

Conditions

  • Anesthesia, Local

Interventions

PROCEDURE

transmuscular QL block

Ultrasound device will be used; The probe is placed in the mid-axillary line cranially to the iliac crest to identify the three muscles of the anterior abdominal wall. Then, scan dorsally keeping the transverse orientation until observing that the transversusabdominus muscle becomes aponeurotic, and this aponeurosis is followed until the QL muscle is clearly visualized with its attachment to the lateral edge of the transverse process of the L2 vertebral body and visualize the thoracolumbar fascia at the lateral edge of the QL muscle. The view of the psoas major muscle (PM) anteriorly, the erector spinae muscle (ESM) posteriorly and the QL muscle adherent to the apex of the transverse process result in a well recognizable pattern of a Shamrock with three leaves (trifoliate).

PROCEDURE

Transversus Abdominus Plane block

Posterior TAP block will be performed on the same side of surgery (unilateral) under ultrasonographic guidance with a with broadband (7-13MHz) linear probe covered with a sterile plastic sheath. Probe will positioned transversely midway between the iliac crest and the costal margin at level of mid axillary line. Once the external oblique muscle (EOM), internal oblique muscle (IOM) and transversus abdominis muscle (TAM) are visualized at the level of the mid axillary line between the 12th rib and the iliac crest, the puncture area and the ultrasound probe were prepared in a sterile manner. After identification of the neuro-facial plane between IOM and TAM, block was performed with 20G spinal needle. The needle will be directed to approach the TAP with "in-plane" USG-guided technique. Once the tip of the needle placed in the space between the IOM and TAM, Inject a 1 ml test dose of lidocaine 2% for hydrovisualization of needle-tip position and confirming its correct postioning.
