Regional anesthesia–cervical plexus block–allowed the patient to cooperate and give useful information, especially during the crucial period of test clamping. In a series of 300 cases, during a period of five years, it was instrumental in avoiding brain damage in 6% of the cases.(Arch Surg 114:103-104, 1979)
