Inguinal Hernia,Quadratus Lumborum Block , Unilateral Intrathecal Block
Conditions
Brief summary
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.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To assess safety of quadratus lumborum block vs unilateral intrathecal block for inguinal hernia repair: complications of the block | 2 hours | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To compare the onset and duration of sensory block between both blocks | 12 hours | the onset of pin brick discrimination and time of first request of analgesics after block performance in each group |
| To compare the time to ambulation | 24 hours | the time till the patient succeed in ambulation |
