Lumbar spinal anesthesia with cervical nociceptive blockade. Critical review of a series of 1,330 procedures

Abstract

Spinal anesthesia with nociceptive blockade to dermatome C4, or C3, is an effective option for surgery on somatic structures distal to the metamer of the third cervical spinal nerve, lasting no more than four or five hours. The method safety depends on the unrestricted respect for the essential rules of proper anesthesia.
