Paravertebral Blocks: Pilot Study to Compare Nerve Stimulation vs. Anatomic Landmarks in Inguinal Hernia Repair

Primary aim:

1. To compare the nerve stimulation vs. anatomic techniques of paravertebral block of T11-L1 in providing surgical anesthesia for patients undergoing inguinal hernia repair.

Secondary aims:

1. Compare VAS pain scores in the two groups of patients over the first 24 hours. 2. Compare opioid intake over the first 24 hours in the two groups of patients.
