Anestesia regional ecoguiada vs buprenorfina intravenosa para manejo del dolor postoperatorio en pacientes sometidos a cirugía bariátrica: una revisión narrativa

Abstract: Bariatric surgery poses a multifaceted challenge for anesthesiologists; however, there is a concomitant requirement to provide adequate perioperative pain control. It is commonly associated with severe postoperative pain, which may lead to ventilatory, endocrine, hemodynamic, immunologic, and other complications. Effective analgesic management is therefore of paramount importance to reduce postoperative complications and length of hospital stay. Various postoperative analgesic techniques have been described, ranging from intravenous opioid-based regimens to neuraxial techniques and, more recently, ultrasound-guided regional anesthesia techniques. These approaches provide effective abdominal analgesia through the administration of local anesthetics at appropriate concentrations. Consequently, a multimodal analgesic strategy combining different interventions— such as the transversus abdominis plane block (TAPB)—is recommended, while the use of opioids for postoperative analgesia should be reserved exclusively for rescue pain management following bariatric surgery.
