Comparison of ketamine-butorophanol and ketamine-diazepam-butorophanol for total intravenous anaesthesia (TIVA) in Dromedary camels - a clinical study.

摘要

This study was conducted to evaluate and compare combinations of TIVA using ketamine-butorophanol (KB) and ketamine-butorophanol-diazepam (KBD) in eight dromedary camels (divided into two groups) and these underwent general surgeries and premedicated with intravenous (IV) 0.2 mg/kg-1 of xylazine. Anaesthesia was induced IV in KB group with 0.8 mg kg-1 of ketamine and 0.1 mg kg-1 of butorophanol, and maintained with constant rate infusion (CRI) of ketamine at 3.3 mg kg-1 hour-1 and by IV bolus injections of butorophanol at 0.1 mg kg-1. Anaesthesia was maintained in KBD group as same with KB group but with including diazepam for induction at 0.1 mg kg-1 and as CRI at 0.3 mg kg-1 hour-1. The quality of induction was rated as poor in KB group and as acceptable in the KBD group. Level of maintained surgical anaesthesia was rated in both groups as marginal for soft tissue surgeries and inadequate for orthopedic surgeries. The mean anaesthetic time was 62.0+or-20.5 minutes in KB group, and 72+or-43.2 in KBD group, while the recovery time was 21.8+or-4.6 minutes in the KB group, and 28.3+5.2 with KBD group.
