Comparative efficacy of analgesic and anaesthetic drugs for high epidural analgesia in black bengal goats

Abstract

The effects of analgesic and anaesthetic drugs on high epidural analgesia in Black Bengal goats were investigated. The animals were divided into five groups (n=8) and a replication of 8 trials was performed in each group at least one week interval. Two percent (2%) lidocaine hydrochloride, 0.5% bupivacaine hydrochloride, 2% lidocaine hydrochloride with adrenaline, ketamine hydrochloride and diazepam were administered into lumbo-sacral (high epidural) space for high epidural analgesia. Bupivacaine hydrochloride significantly (P < 0.05) decreased respiration rates, rectal temperature, however, increased heart rates during high epidural analgesia with prolonged analgesia compared to other drugs. Lidocaine hydrochloride showed a rapid onset and excellent analgesia and did not produce any side effects whereas, diazepam exhibited delay onset with short duration of analgesia. It seems that 2% lidocaine hydrochloride is effective for high epidural analgesia in goats.
