Key result
Nerve stimulator-guided femoral nerve block provided superior pre-operative analgesia compared with fascia iliaca compartment block (mean difference in pain score reduction 0.9; 95% CI 0-1.8; p=0.047).
Why the study?
Does nerve stimulator-guided femoral nerve block improve analgesia and reduce opioid consumption compared to fascia iliaca compartment block in patients awaiting surgery for fractured neck of femur?
RCT (n=110)

Supports nerve stimulator-guided femoral nerve block for pre-operative analgesia in femoral neck fractures; extends evidence favoring targeted over compartment blocks.
Newman et al. (2013) conducted an RCT in Femoral neck fracture (n=110). Nerve stimulator-guided femoral nerve block vs. Fascia iliaca compartment block was evaluated on Reduction in visual analogue pain score 2 hours after the block (MD 0.9, 95% CI 0-1.8, p=0.047). Nerve stimulator-guided femoral nerve block provided superior pre-operative analgesia compared with fascia iliaca compartment block (mean difference in pain score reduction 0.9; 95% CI 0-1.8; p=0.047).
