采用戊巴比妥钠麻醉口腔常用实验动物 ,比较不同药物浓度、配制方法等差别。结果显示小于常规麻醉剂量的戊巴比妥钠可使口腔颌面手术顺利完成 ;过滤除菌方法优于高压灭菌法 ;即配即用 ,更换不同厂家或批号麻药时 ,应首先进行预实验是保证效果的关键 The use of sodium pentobarbital anesthesia commonly used oral laboratory animals, compare different drug concentrations, preparation methods and other differences. The results showed that pentobarbital sodium, which is less than the conventional anesthetic dose, can successfully complete oral and maxillofacial surgery. The method of filtration and sterilization is superior to the method of autoclaving. That is, the pre-experiment Is the key to guarantee the effect
