Proximal sciatic nerve block is indicated:
– for surgical anaesthesia with peripheral nerve blocks that includes surgery of the thigh or knee
– for surgical anaesthesia with peripheral nerve blocks that includes a thigh tourniquet
– as an alternative to popliteal sciatic nerve block when that is not feasible
Proximal sciatic nerve blocks are:
– the subgluteal approach
– the anterior approach combined with a saphenous nerve block (SPEDI)
– the parasacral parallel shift approach to block the sacral plexus (as an alternative to subgluteal approach or
SPEDI – single penetration dual injection)
