Does continuous blockade of the lumbar plexus with bupivacaine improve pain relief in patients undergoing surgery for femoral neck fractures under spinal anaesthesia receiving acetylsalicylic acid?
Continuous blockade of the lumbar plexus with bupivacaine offers no major additional pain relief over rectal acetylsalicylic acid after surgery for femoral neck fractures under spinal anaesthesia.

Does not support routine continuous lumbar plexus blockade with acetylsalicylic acid; confirms lack of major additional benefit after femoral neck fracture surgery.
In a randomized, double-blind investigation the analgesic effect of continuous blockade of the lumbar plexus as an adjunct to acetylsalicyclic acid by suppository after surgery for femoral neck fractures under spinal anaesthesia was examined in 20 patients. Before surgery, a catheter was inserted into the femoral nerve sheath. The patients were allocated randomly to receive bupivacaine or saline by bolus and then continuous infusion, started immediately after the operation. No statistically significant differences in additional morphine requirements, visual analogue pain scores or adverse effects were observed between the two treatment groups. It is concluded that continuous blockade of the lumbar plexus as an adjunct to rectal acetylsalicyclic acid offers no major additional pain relief after surgery for femoral neck fractures under spinal anaesthesia.

Spansberg et al. (1996) conducted an RCT in femoral neck fractures (n=20). Continuous blockade of the lumbar plexus (bupivacaine) vs. Saline was evaluated on Additional morphine requirements, visual analogue pain scores, and adverse effects. Continuous blockade of the lumbar plexus with bupivacaine as an adjunct to acetylsalicylic acid offered no major additional pain relief after surgery for femoral neck fractures compared to saline.
