Why the study?
Does continuous blockade of the lumbar plexus with bupivacaine reduce pain or morphine requirements in patients after surgery for femoral neck fractures?
Does continuous blockade of the lumbar plexus with bupivacaine reduce pain or morphine requirements in patients after surgery for femoral neck fractures?
Continuous blockade of the lumbar plexus with bupivacaine does not provide additional pain relief over rectal acetylsalicylic acid after surgery for femoral neck fractures.

No additional analgesia from continuous lumbar plexus blockade versus rectal acetylsalicylic acid after femoral neck fracture surgery; challenges its routine use.
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.
