AbstractPlexus nerve blocks of the lower limb have been described for many years but were seldom used until recently. Postoperative analgesia is one of the main indications of these blocks. The blockade of both lumbar and sciatic plexuses is required for most of the surgical procedures performed on the proximal part of the lower limb. Nerve stimulators account for less difficulties to perform such blocks and results are more reliable. Several pharmacokinetic studies have documented that toxic thresholds of plasma concentrations of local anaesthetics are not reached with the doses commonly injected. Many different techniques and landmarks have been described providing several alternatives to perform these blocks according to the type and the localisation of the surgical procedure. Extensive indications are reported for day case surgery or patients at risk.
