Brief Summary

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

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.
