15 Obturator Block Perspective This block is most often combined with the sciatic, femoral, and lateral femoral cutaneous nerve blocks to allow surgical procedures on the lower extremities. If an operation on the knee using these peripheral blocks is planned, the obturator block is often essential. Another use for this block is in patients who have hip pain. It can be used diagnostically to help identify the cause of pain because obturator nerve block may provide considerable pain relief if the nerve’s articular branch to the hip is involved in pain transmission. The block also may be useful in the evaluation of lower extremity spasticity or chronic pain syndromes. Patient Selection As with femoral and lateral femoral cutaneous nerve blocks, elicitation of paresthesias is not essential for obturator block. Any patient able to lie supine is a candidate. Pharmacologic Choice Motor blockade is most often not necessary for surgical patients receiving obturator nerve block; thus, lower concentrations of local anesthetics are appropriate for obturator block: 0.75% to 1.0% lidocaine or mepivacaine, 0.25% bupivacaine, or 0.2% ropivacaine.
