Lower limb amputations performed with anterior quadratus lumborum block and sciatic nerve block

The anterior quadratus lumborum block (QLB) has been used as both a trunk nerve block and a lower limb nerve block [1,2]. Compared with lumber plexus nerve block, anterior QLB can be safety performed on patients who take anticoagulant because of a shallow nerve block. We report two successful cases of lower limb amputation with an anterior QLB on a patient who had previously lumber surgery. Case 1 was a 75-year man (173cm, 78kg) who was scheduled for a right above-knee amputation because of arteriosclerosis obliterans.
