The reverse sural artery neurocutaneous flap under combined sciatic and femoral nerve block for lower limb defects: a series of ten cases

The case of reverse sural artery neurocutaneous flap done for lower leg defects under combined sciatic and femoral nerve block is presented. Doing the flap using this method of anesthesia makes the positioning changes necessary during surgery easy. All flaps survived. Nine out of the ten blocks acted satisfactorily. The technique of giving the combined block is described in brief. The mean time of onset of action was 16.62 min, and the mean duration of action was 6.26 h using 1% Lidocaine with 1 in 200,000 adrenaline.
