Summary

This clinical trial aims to evaluate the effectiveness of an ultrasound-guided nerve block technique as the sole anesthetic method for patients undergoing outpatient umbilical hernia surgery. The procedure, called rectus sheath block (RSB), involves injecting local anesthetic near the abdominal muscles to reduce pain during and after surgery. The study will compare two groups of adult patients: one receiving the nerve block with a medication called clonidine added to the anesthetic solution, and the other receiving the same block without clonidine. Clonidine may help improve pain control and reduce the need for additional pain medications. By analyzing pain scores, recovery quality, and potential side effects, the study seeks to determine whether the use of clonidine in this context is safe, cost-effective, and beneficial for patient recovery. Participants will answer questionnaires about their pain and recovery during the first 48 hours after surgery.

Interventions

DRUG

Rectus Sheath Block

Participants in this arm will receive bilateral ultrasound-guided rectus sheath block (RSB) with a solution containing 8 mL of lidocaine 2% + 8 mL of ropivacaine 1%, diluted in 0.9% saline to a total volume of 20 mL, each side, without the addition of clonidine.

DRUG
