Lateral Femoral Cutaneous Block

14 Lateral Femoral Cutaneous Block



Perspective


When this block is combined with other lower extremity blocks, it allows lower leg procedures to be carried out with fewer complaints of tourniquet pain. It also allows superficial procedures on the lateral thigh, including skin graft harvesting. In a pain practice, it allows the diagnosis of myalgia paresthetica, which is a neuralgia involving the lateral femoral cutaneous nerve.




Patient Selection


Like femoral nerve block, this block is carried out with the patient in the supine position. Thus, almost any patient is a candidate for a lateral femoral cutaneous block.



Pharmacologic Choice


The same concerns about local anesthetic choice that were outlined for sciatic and femoral blocks (Chapters 12 and 13, respectively) apply to the lateral femoral cutaneous block. If multiple lower extremity blocks are being used, the operator must consider the total dosage being administered. Because the lateral femoral cutaneous nerve does not have motor components, a lower concentration of 10 to 15 mL of local anesthetic is effective.
