Abstract: : The aim of our study was to evaluate the efficacy of Paravertebral block in unilateral inguinal hernia repair comparing with spinal anaesthesia with respect to post operative analgesia, ambulation, perioperative and postoperative complications. Paravertebral block can be used as an alternative to spinal anaesthesia in unilateral inguinal hernia repair. It offers better hemodynamic control, prolonged post operative analgesia and early ambulation compared to spinal anaesthesia.
