Lumbar-Sacral Plexus Block vs Fascia Iliaca Block Plus Low-Dose Spinal Anesthesia for Femoral Neck Fracture Surgery

The global incidence of hip fractures continues to rise, and most patients require surgical intervention. Due to advanced age, frailty, and multiple comorbidities, anesthetic management in this population is particularly challenging. Intraoperative hypotension has been shown to be associated with increased short- and long-term mortality, regardless of the anesthetic technique used.

To reduce the incidence of hypotension, various neuraxial and peripheral nerve block techniques have been investigated. While spinal anesthesia provides reliable surgical conditions, it may still cause significant hypotension. Peripheral nerve blocks, such as lumbar and sacral plexus blocks or fascia iliaca block, tend to preserve hemodynamic stability and are associated with a lower incidence of motor blockade.

Recently, combined techniques using low-dose spinal anesthesia together with fascial plane blocks have been introduced to balance the advantages of neuraxial anesthesia and peripheral nerve blocks. However, there is still no consensus on the optimal regional anesthesia strategy to minimize severe hypotension while ensuring effective analgesia in patients undergoing femoral neck fracture surgery.
