  "abstract": "Background and Aims Abdominal wall blocks (AWB) are increasingly used as part of multimodal analgesia, offering a safer, simpler alternative to neuraxial techniques. Blocks such as transversus abdominis plane (TAP), quadratus lumborum (QL), ilioinguinal/iliohypogastric (II/IH), and rectus sheath (RS) have shown varied effectiveness depending on surgery type.Methods Retrospective descriptive study conducted at a tertiary center, including 102 patients, aged ≥18 years, who underwent abdominal surgery with an AWB between January 2023 and December 2024. Data were obtained from electronic medical records and included demographics, ASA status, surgical specialty, urgency, block type, and anesthetic details. Outcomes assessed were postoperative pain, opioid use, rescue analgesia, and complications within 72 hours.Results In two years, 102 patients underwent abdominal surgery with an AWB. Most were female (72.5%) with a mean age of 59. ASA II and III predominated (56.4% and 30.4%). Surgeries were mainly elective (67.6%), across general surgery (49%), gynecology (41.2%), urology (3.9%), and obstetrics (5.9%). Blocks performed included TAP (57.8%), QL (34.3%), II/IH (3.9%), and RS (3.9%), using ropivacaine (0.2–0.75%), mean 125 ± 33 mg. Mean pain score was 1.78 ± 1.57. Within 24 h, 26.4% required opioid rescue. No short-term complications were observed.Conclusions AWB proved to be safe and effective for postoperative analgesia in abdominal surgeries, with low pain scores, modest opioid use, and no short-term complications. These results support their role as reliable alternatives or adjuncts to neuraxial techniques, especially within multimodal and enhanced recovery protocols.",
