Abstract

Thirty donkeys of both sexes were used in this study. The animals were classified into 3 groups (each of ten animals). The technique for catheterization of the epidural space has been described. An initial dose of 1, 2 and 3 ml lidocaine hydrochloride 2% was injected between L1-L2 or L2-L3 for each animal in groups A, B and C respectively through the correctly placed epidural catheter. The analgesic effects of 2% lidocaine hydrochloride has been determined. The best dose of this local anaesthatic for production of cranial segmental epidural analgesia was 2 ml (group B). The analgesic period in this group was about one hour after the first injection. It has been maintained for another 40 minutes by fractional bolus of 1 ml lidocaine H CL 2%. The technique was found to be easily performed and effective for continuous cranial segmental epidural analgesia in donkeys.
