The lidocaine patch is currently only permitted for post herpetic neuralgia but the investigators want to study its effectiveness in post operative pain after inguinal herniorrhaphy
- Detailed Description
After open unilateral inguinal herniorrhaphy, patients are randomly divided into group L and group P groups. Group L attaches two lidocaine patches for 12 hours, above and below the incision site. Group P attaches two placebo patches for 12 hours, above and below the incision site. Pain scores are recorded for 30 minutes, 2 hours, 24 hours, and 1 week after surgery.
