Advances of regional nerve blocks for postoperative analgesia in laparoscopic gynecological surgery: precision, innovation, and future directions

Laparoscopic gynecological surgery, despite its minimally invasive nature, is frequently associated with significant postoperative pain, encompassing somatic, visceral, and referred components. This pain poses challenges to patient recovery and increases opioid consumption, highlighting the need for effective, opioid-sparing strategies within Enhanced Recovery After Surgery (ERAS) pathways. This narrative review explores the evolution of regional nerve blocks as a cornerstone of postoperative pain management in this surgical context. It traces the progression from early, nonspecific techniques such as local infiltration to the modern era of precise, ultrasound-guided fascial plane blocks. The evidence supporting major truncal blocks including the Transversus Abdominis Plane Block (TAPB), Quadratus Lumborum Block (QLB), and Erector Spinae Plane Block (ESPB) is critically examined, demonstrating a shift from primarily somatic analgesia to techniques that also address visceral pain. Approaches to optimizing block efficacy and duration, including the use of pharmacological adjuvants (e.g., dexamethasone, dexmedetomidine) and dose-optimization strategies, are discussed. The synthesis of current evidence underscores the role of regional nerve blocks as a foundational component of modern multimodal analgesia, essential for facilitating early recovery and improving patient outcomes. Looking ahead, the field is moving toward personalized analgesia, where block selection is tailored to the specific surgical "pain fingerprint" and individual patient needs, guided by ongoing advancements in technology.
