速眠新麻醉剂在绵羊胚胎移植手术中的应用

Application of SU-MIAN-XIN in sheep's embryo transplant

在绵羊胚胎移植供、受体麻醉中,用速眠新麻醉剂以肌肉注射和静脉注射2种方法给药,测定了麻 醉绵羊进入麻醉期的各项生理常数,观察了麻醉诱导期、麻醉期、苏醒期绵羊的表现及其所用时间,综合评定了麻 醉效果。结果表明,两种麻醉方法均可以取得良好的麻醉保定效果。与肌肉注射麻醉相比,静脉注射麻醉的用药量 只有肌肉注射的1／5-1／7,麻醉绵羊进入麻醉期时间短(平均1．03-3．82 min),手术后苏醒早,有利于提高胚胎移 植手术的效率,而且安全性较高。研究还发现,不同品种绵羊对速眠新的反应有差异,体重、体况、气候等因素均影 响麻醉剂的用药量和麻醉效果。

The aim of this study was to evaluate anesthesia effect of SU-MIAN-XIN administered intravenously and intramuscularly on sheep donors and recipients for embryo transplant. Physiological constants ,narcosis efficiency and the time required to get anesthesia were examined and compared with results as follows .both impartation ways had reliable narcosis effect, however, vein anesthesia needed 4/5--6/7 less dosage to get into and shorter （1.03-3.82 min） time to relieve from anesthesia than that of intramuscular anesthesia. Meantime,it was also safer and more efficient to use;the breed of sheep affected responses and body weight,physique,and weather also affect the dose and effect of narcosis.
