摘要

本研究的目的是研究静脉注射克罗酞碱是否对健康站立的马产生显著的镇静作用以及生理变化。6匹8岁、体重415kg的母马采用交叉设计,分别静脉注射TA(乙酰丙嗪:50μg.kg-1)、TC (crotalphine: 0.01μg.kg-1)和TX (xylazine: 1000μg.kg-1)。在60分钟内的不同时间点,记录生理变量:心率、呼吸频率和直肠温度。头距地面高度(HHG)以厘米为单位进行评估。数据分析采用方差分析加Dunnett检验或Friedman加Dunn检验,显著性在5%以下。与Mb相比,M5和M10的心率分别显著降低(28±7、26±6和40±8次/分钟-1);p = 0.0004)。呼吸频率和直肠温度在组间和时间点间无差异。与Mb相比,各时间点各组HHG均显著降低(p<0.0001)。综上所示,crotalphine不能对健康站立的母马产生可靠和持久的镇静作用,也不会以临床相关的方式影响心肺变量。

Cardiorespiratory/sedative effects of a peptide identified in crotalic venom compared to acepromazine and xylazine in horses
ABSTRACT The purpose of this study was to investigate whether intravenous crotalphine produces significant sedation, as well as physiological changes, in healthy standing horses. Six mares, aged 8 years and weighing 415kg underwent three different treatments in a crossover design: TA (acepromazine: 50μg.kg-1), TC (crotalphine: 0.01μg.kg-1) and TX (xylazine: 1000μg.kg-1), intravenously. At various time points over 60 minutes, physiologic variables were recorded: heart rate, respiratory rate, and rectal temperature. The head height from the ground (HHG) was evaluated in centimeters. Data were analyzed using ANOVA followed by Dunnett’s test or Friedman followed by Dunn’s test, under 5% significance. Heart rate decreased significantly at M5 and M10 compared with Mb in TX (28±7, 26±6 and 40±8 beats/minute-1, respectively; p=0.0004). Respiratory rate and rectal temperature did not differ among groups or time points. The HHG significantly decreased in all groups compared with Mb at various time points (p<0.0001). In conclusion, crotalphine did not produce reliable and durable sedation in healthy standing mares and did not influence cardiorespiratory variables in a clinically relevant manner.
