Abdominal Surgery Performed in Awake Patients Under Neuraxial Anesthesia: A Systematic Review Across Surgical Specialties

Background: Neuraxial anesthesia (NA) is increasingly utilized across various surgical specialties, particularly for abdominal procedures, making it a potential alternative to general anesthesia (GA). Methods: This narrative review was conducted following the PRISMA guidelines for systematic reviews to report on the application of NA worldwide and across various surgical fields. Results: The findings indicate that while NA is gaining popularity, its adoption varies significantly by procedure type and specialty. Evidence supporting its use in major abdominal surgeries remains limited, with most studies focusing on pelvic and minor procedures. The emerging concept of awake surgery under NA shows promising potential, as preliminary data suggest benefits in reducing perioperative morbidity and enhancing recovery. Despite these advancements, gaps in the literature highlight the need for further high-quality trials to establish NA as a safe and routine alternative to GA. Conclusions: NA is increasingly explored across different surgical specialties as a feasible and effective option for abdominal procedures. However, despite this growing interest, solid evidence supporting its use in major abdominal surgery remains limited.
