在病理生理学的实验教学过程中，制备高血钾动物模型时，绝大多数是应用头皮针或静脉套针经耳缘静脉推注适当浓度的ＫＣｌ溶液〔１，２〕。这种方法既不易掌握注入ＫＣｌ溶液的速度，亦不能以均恒的速度给药。另外，多次经同一途径注射给药时，常因操作技术不佳而损伤兔耳... In the pathophysiology of experimental teaching process, the preparation of hyperkalemia animal model, the vast majority of the application of scalp needle or intravenous trocar through the ear vein injection of appropriate concentrations of KCl solution [1,2]. This method is neither easy to grasp the rate of injection of KCl solution, nor can be administered at a constant rate. In addition, many times by the same route of injection, often due to poor operating skills and damage rabbit ears ...
