Evaluation of Efficacy of Lumbar Plexus Bloc After Hip Surgery
Compare lumbar plexus block with ropivacaine 0.475%, 0.4 ml/kg to saline. Each group randomized, includes 30 patients. block performed preoperatively Surgery under general anesthesia. Postoperative evaluation of pain (VAS) as first endpoint, and also morphine consumption via PCA device. Follow-up : 24h.
Expectation : sizeable reduction of pain with block, of duration.

Compare lumbar plexus block (randomized)
- ropivacaine 0.475%, 0.4 ml/kg
- saline 0.4 ml/kg . Each group includes 30 patients.
Block performed preoperatively.
Surgery under general anesthesia (sufentanil, propofol, atracurium ; maintenance : sevoflurane and nitrous oxide in O2. Sufentanil added peroperatively as clinically needed.
Postoperative evaluation of pain (VAS, by an independant blind observer) as first endpoint, and also morphine consumption via PCA device.
Adverse effects (nausea, vomiting, etc) recorded
Follow-up : 24h. Expectation : sizeable reduction of pain with block, of duration.
