Ultrasound-Guided Transverse Abdominis Plane Block as a Component of Multimodal perioperative Analgesia:current Evidence and clinical perspective

Effective postoperative pain management is crucial for patient recovery after abdominal surgery. The transversus abdominis plane (TAP) block, guided by ultrasound, has emerged as a useful regional technique to control pain while minimizing opioid use. We conducted a review of studies published between 2008 and 2022, searching PubMed, Google Scholar, and the Cochrane Library. Keywords included “TAP block,” “ultrasound-guided,” and “postoperative analgesia.” A total of 24 studies—comprising randomized trials, observational studies, and meta-analyses—were included. Evidence shows that TAP block effectively reduces pain scores and opioid consumption across various abdominal surgeries, including cesarean sections, appendectomies, colorectal procedures, bariatric surgery, and hysterectomies. Its use in Enhanced Recovery After Surgery (ERAS) pathways supports early mobilization and patient satisfaction. Variations in techniques, anesthetic doses, and surgical procedures create some inconsistencies in outcomes. Future research should aim to standardize TAP block protocols, compare them with other regional techniques, and explore long-term benefits such as reduced chronic pain. Ultrasound guidance improves accuracy and safety, making TAP block a valuable tool in perioperative care.
