compare between Quadratus lumborum block and unilateral intrathecal block for patients undergoing inguinal hernia repair regarding the quality of anesthesia and hemodynamic stability of patients.
comparison between unilateral intrathecal block anesthesia (unilateral SA) and Quadratus lumborum block for inguinal hernia repair unilateral intrathecal block is widely used nowadays for unilateral inguinal hernia repair, providing intense sensory and motor blockade. Limiting the block to the operative site by using small doses of hyperbaric solutions injected slowly through a directional needle and maintaining a lateral decubitus position for a certain duration has been proposed, to produce high quality, long-duration analgesia, with minimal hemodynamic adverse events. Previous case report studies stated that we can use Quadratus Lumborum Block as the sole anesthetic technique for open hernia repair.

Quadratus lunborum block
To assess safety of quadratus lumborum block vs unilateral intrathecal block for inguinal hernia repair: complications of the block
complications of the block in each group like inadequate blockade detected by increased dose of sedation required in this group ,hemodynamic instability related to the block detected by frequent monitoring of the blood pressure and heart rate
Time frame: 2 hours
To compare the onset and duration of sensory block between both blocks
the onset of pin brick discrimination and time of first request of analgesics after block performance in each group
Time frame: 12 hours
To compare the time to ambulation
the time till the patient succeed in ambulation
Time frame: 24 hours
