Local anaesthesia for laminectomy surgery

Abstract

Neurosurgical patients presenting for laminectomy surgery may have premorbid pathology that either contraindicates general anaesthesia or at least represents a significant risk to the patient. We present a sample case from a series of ten patients in whom laminectomy surgery was performed under local anaesthesia. The mean duration of surgery was 98 minutes and the average dose of lignocaine used was 1.91 mg/kg and, therefore, within safe limits. One patient was converted to a general anaesthetic. We believe that local anaesthesia can offer a safe and satisfactory alternative, in patients who may otherwise be denied surgery. The additional advantage of awake neuro-monitoring, may also reduce the risk of inadvertant spinal cord injury.
