Observing How Deep Rectus Sheath Block Helps Pain and Recovery After Abdominal Surgery

What this Trial Is About

Researchers are studying the effectiveness of the Deep Rectus Sheath Preperitoneal block in adults undergoing open or laparoscopic abdominal surgery. The goal is to see if this ultrasound-guided pain relief technique improves recovery and controls pain better than standard care or other nerve block methods such as TAP, ESP, or QL blocks. This observational clinical study is non-interventional and focuses on routine clinical care outcomes. Participants will receive pain management as per standard practice, which may include systemic analgesia alone, the Deep Rectus Sheath block combined with standard care, or other fascial plane blocks combined with standard care. Details such as the type of block, timing, technique, and local anesthetic dosages will be recorded. All patients will also receive multimodal pain relief following hospital protocols, with opioids reserved for rescue treatment. During the study, participants recovery quality will be measured using the Quality of Recovery-15 QoR-15 score at 24 hours after surgery. Pain levels at rest and with movement will be tracked up to 48 hours, along with analgesic use, time to first pain medication request, mobilization time, and any complications. Safety monitoring includes checking for block-related issues and neurological symptoms up to 7 days after surgery. The study is expected to complete within 12 months.
