About this trial
The goal of this observational study is to learn about the effectiveness of the Deep Rectus Sheath (Preperitoneal) block in patients undergoing abdominal surgery. The main question it aims to answer is:
Does the Deep Rectus Sheath block improve postoperative recovery and pain control compared to standard care or other fascial plane blocks in patients undergoing abdominal surgery?
Participants undergoing open or laparoscopic abdominal surgery as part of their routine clinical care will receive analgesic management according to standard practice, which may include systemic analgesia alone, Deep Rectus Sheath block, or other fascial plane blocks (such as TAP, ESP, or QL), depending on anesthesiologist choice. Postoperative outcomes will be collected prospectively, including quality of recovery (QoR-15 at 24 hours), pain scores at rest and during movement up to 48 hours, analgesic consumption, time to first analgesic request, mobilization time, and occurrence of complications.

Quality of Recovery-15 (QoR-15) score
The Quality of Recovery-15 (QoR-15) is a validated patient-reported outcome measure designed to assess the quality of postoperative recovery across multiple dimensions of physical and psychological well-being. The questionnaire consists of 15 items, each scored on an 11-point numerical scale, resulting in a total score ranging from: Minimum score: 0 → extremely poor quality of recovery Maximum score: 150 → excellent quality of recovery Higher QoR-15 scores indicate a better postoperative recovery experience. The questionnaire evaluates five key domains: Pain Physical comfort Physical independence Psychological support Emotional state

Postoperative pain
The Numerical Rating Scale (NRS) is a validated and widely used tool for the assessment of pain intensity in clinical practice and perioperative research. Patients are asked to rate their pain on a numerical scale ranging from: 0 → no pain 10 → worst pain imaginable
