[Epidural sacral anesthesia with 3% mepivacaine in rectal surgery].

: The authors think that the sacral epidural anaesthesia effected with Mepivacaine 3%, 6 ml (180 mg) and Fentanyl 2 ml (100 mcg) is perfectly indicated for the proctologic surgery as it is of simple execution and presents a short latency (12 min.), good deepness and perfect haemodynamic stability. Besides, it does not endanger the lower limbs innervation. No urinary retention.
