Detailed Description:

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.
