Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

a novel approach for TQL (anterior Q.L) block aiming mainly for terminal branches of lumbar plexus. The technique is described as Para-Spinous Saggital Shift Q.L block, done at L4 transverse process level in saggital orientation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

With this approach, we think it has advantages of easy identification, better caudal LA spread till under fascia iliaca, with the psoas major muscle provides a better protective barrier against accidental needle entry into the peritoneal cavity, the endpoint is injection within a fascial plane, rather than a specific motor response contact where the lumbar plexus stimulation is not sought, so there is minimal risk of nerve injury, inadvertent dural cuff puncture and intrathecal spread of local anesthetic. And finally optimal insertion of catheter in long axis of Q.L and psoas major if continuous analgesia is planned.
