Effectiveness and Safety of Adding Clonidine to Ultrasound-Guided Rectus Sheath Block for Outpatient Umbilical Hernia Repair in Adults Aged 18 to 65

What this Trial Is About

Researchers are evaluating the use of an ultrasound-guided nerve block technique called rectus sheath block RSB as the only anesthetic method for adults undergoing outpatient umbilical hernia surgery. The study compares two groups one receiving RSB with an added medication called clonidine, and the other receiving RSB without clonidine. The goal is to see if clonidine improves pain control, reduces the need for additional pain medications, and supports better recovery without adding risks. Participants will receive bilateral RSB performed with real-time ultrasound guidance using a specific needle and monitored sedation as needed. The intervention group receives a local anesthetic solution with clonidine, while the control group receives the same anesthetic without clonidine. Both solutions include lidocaine and ropivacaine diluted in saline and administered on each side. The study is randomized, double-blind, and controlled, with careful data management and safety monitoring during surgery. During the first 48 hours after surgery, participants will answer questionnaires assessing pain intensity, recovery quality, and sedation levels. Pain is measured at the recovery unit, 24 hours, and 48 hours post-surgery. Researchers will also track opioid use during and after surgery, as well as any side effects like nausea or vomiting. The study aims to provide important information about improving anesthesia techniques for safer and more comfortable hernia repair.
