Abstract :
Washout of the epidural space with normal saline has been proposed to accelerate recovery from epidural block with contradictory results in human clinical studies. The present study aimed to examine the effect of epidural washout with saline on reversing epidural anesthesia with lidocaine 2% with or without adrenaline in dogs. Twenty four dogs were used in the study. Dogs were divided into four groups (n=6); group (A) epidurally injected by lidocaine 2%, group (B) epidurally injected by lidocaine 2% with adrenaline, group (C) epidurally injected by lidocaine 2% and after 30 minute received epidural washout with 10 ml normal saline and group (D) epidurally injected by lidocaine 2% with adrenaline and after 30 minute received epidural washout with 10 ml normal saline. The sensory and motor functions were evaluated and values of heart rate, respiratory rate and rectal temperature were recorded. Serum lidocaine concentrations were measured. The obtained results showed that, epidural washout with 10 ml normal saline significantly fastens the time of complete sensory and motor block recovery. There were no significant differences in heart rate, respiratory rate and body temperature. Epidural washout does not affect vascular absorption of epidural lidocaine. Epidural washout with normal saline can safely use to hasten complete sensory and motor block recovery following epidural anesthesia with lidocaine 2% with or without adrenaline in dogs.
