Comparative efficacy of analgesic and anaesthetic drugs for high epidural analgesia in black bengal goats
Keywords:Analgesics, anaesthetics, high epidural analgesia, goats
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.
