静松灵硬膜外腔注射对绵羊的镇静镇痛效果及其血液变化

The studes on sedative and Analgesic Effects of Epidural Injecting Jingsongling and the Changes of Blood Gases and Acid Base Bal ance in sheep

对８只绵羊以静松灵０．３０ｍｇ／ｋｇ硬膜外腔注射，观察镇静和镇痛效果，并对血液气体和酸碱状态的变化进行定量分析。结果表明，静松灵硬膜外腔注射较静脉和肌肉注射有更长的镇静镇痛作用，对血液成分的影响显著（Ｐ＜０．０５），故此种注射法确为安全有效之法。

The Jingsongling were injected epltiurally in 8 sheep at a dosage of 0.3mg/kg,the sedative and analgesic effects were observed clinically,the changes of blood gases and acid-alkanility balance status were also measured quantitatively. The results showed the epidural in-jecting Jingsongling are characterized with a longer sedation and analgesia duration than its beingutilized intramuscutarlly and intravenously; the cardiopulmonary functions be suppressed evident-ly·Such the epid ural injection of Jingsongling will be a safe and effective method in veterinarysurg ical operations.
