[Combined block of femoral, sciatic, obturator nerves and lateral cutaneous nerve block with ropivacaine for leg amputation above the knee].
A 76-yr-old male presented for leg amputation above the knee. The patient complained of dyspnea due to pulmonary embolism occurring 3 weeks before operation. In addition, the patient could not report paresthesias because he had suffered from a cerebral infarction. Anesthesia was performed with combined block of femoral, sciatic, obturator nerves and the lateral cutaneous nerve of the thigh. The nerves were anesthetized with 0.75% ropivacaine solution 31 ml by use of an electrical nerve stimulator and an insulated needle. Nerve stimulation technique is the best choice for patients who are unable to report paresthesias reliably.
