噻芬太尼对羚牛的保定研究

羚牛(Budorcas taxicolor)属国家第一类保护的珍稀动物。羚牛包括4个亚种,其中四川亚种和秦岭亚种为我国所特有。随着野生动物科研工作的发展。有关羚牛的生态、遗传、血液生化等研究工作正逐步进行,羚牛的疾病诊治、捕捉、搬迁等工作也日益频繁。羚牛性情凶猛,不易保定,人工强行保定极易造成动物和人员的伤亡。因此,如何解决羚牛的化学保定问题,是进一步开展羚牛科研工作的重要条件之一。

IMMOBILISATION OF BUDORCAS TAXICOLOR USING THIOFENTANIL

This paper reports the results of using Thiofentanil for immobilisation of Budorcas taxicolor.A total of 11 B.taxicolor are immobilised 21 times (Table 1 ) . Dosage rates varing from 4.7 to 16μg/kg are successfully used.The average dosage is 11.6μg/kg.Thiofentanil induces relatively short induction time due to its powerful and rapid absorption.Induction time ranges from 1 to 7 minutes.The average induction time is 2.4 min.Very little excitement is noticed during the induction phase.The induction phase usually terminates in analgesic narcosis, characterised by sternal or lateral recumbency.The immobilisation time is over 1.5 hours.Respiratory depression is mild and no death occurs in this trials. The action of Thiofentanil can rapidly and effectively be reversed with the usual Morphine antagonist Nalorphine.The recovery time ranges from 1 to 11 min. and the average time 2.9 min,The results show that Thiofentanil is considered to be a powerful, safe and effective Morphine-like analgesic immobiliser.So we suggest that Budorcas taxicolor can be immobilised by using Thiofentanil with the optimal dosage of 10μg/kg.
