Background and Objectives: Patients with femoral neck fractures often suffer severe pain. This randomized controlled clinical study compared the effect of femoral nerve block (FNB) and fascia iliaca compartment block (FICB) in this population.
Patients and Methods: Forty-six patients were randomly assigned to one of the two groups: FNB group (femoral nerve block, n=23) or FICB group (fascia iliaca compartment block, n=23). Before positioning for spinal anesthesia, patients received FNB with 15 mL of 0.5% ropivacaine or FICB with 40 mL of 0.5% ropivacaine. Pain was evaluated using a visual analogue scale (VAS) at rest and during hip flexion after admission to the operation room; at 3, 5, 8, and 10 min after analgesia intervention; and during positioning for spinal anesthesia. Positioning was attempted after 10 min of analgesia intervention in each group. Time required to perform spinal anesthesia, quality of positioning, and patient satisfaction were documented.
Results: The VAS scores in the FNB group were significantly lower than those in FICB group at 3 and 5 min after analgesia intervention (P=0.000). However, there were no significant differences in VAS between groups at 8 or 10 min or during positioning.
Conclusion: FNB and FICB produce similar analgesic effects in patients with femoral neck fractures, but FNB has a more rapid onset of pain relief.
