ABSTRACT:
A method of combined spinal and epidural anesthesia includes (a) inserting a catheter into an epidural space in a patient; (b) performing a spinal anesthesia for the patient; (c) monitoring an analgesic level of the spinal anesthesia in the patient; (d) in the event that the analgesic level of the spinal anesthesia is found to be insufficient in the patient, injecting a physiological saline solution through the catheter into the epidural space, thereby rapidly expanding the analgesic level of the spinal anesthesia in the patient. Preferably, the analgesic level of the spinal anesthesia is monitored at a point of time about 10 minutes after the spinal anesthesia. It is also preferred that the amount of injection of the physiological saline solution be adjusted as a function of the height of the patient to rapidly raise the analgesic level of the spinal anesthesia to a desired level in the patient. The present method is based upon the elucidation of a true mechanism of an epidural anesthesia that is used after the performance of a spinal anesthesia in the course of combined spinal and epidural anesthesia, the elucidation being performed by using a radiographic diagnosis with a myelographic technique.
