Sacral plexus nerve blocks

Sciatic nerve blocks are recommended for operations on the foot (especially clubfoot) and the leg. A complementary block of the saphenous or femoral nerve is often necessary to anesthe-tize the skin of the medial part of the leg. Due to the simplicity of the technique and distal location, the popliteal approach to the sciatic nerve should always be considered first.[15,32] Proximal approaches are selected only when surgery of the knee is planned (which is unusual in pediatric patients) or when the posterior femoral cutaneous nerve should be simultaneously blocked (a proximal approach to the sciatic nerve almost always results in complete blockade of this nerve, even though it runs in an apparently separate fascial tunnel).
