摘要
目的:比较传统自制的动脉插管和使用直型留置针代替动脉插管在医学机能实验中应用的情况,找出一种便于学生操作、成功率高的动脉插管方法。方法:将40例实验动物随机分为A组和B组,分别用传统自制的动脉插管和用18G×29MM型号直型静脉留置针做动脉插管行颈总动脉插管术,并对2组插管方法的手术时间及成功率进行比较和评价。结果:用传统自制的动脉插管和用直型留置针做动脉插管2组比较,在手术时间和插管成功率上直型留置针做动脉插管方法明显高于传统的动脉插管方法。结论:直型留置针做动脉插管与传统自制的动脉插管相比具有简单、快速、准确、安全及成功率高等优点。用直型留置针代替传统动脉插管的最大优势是合理地解决了自制动脉插管口径大小不一、无固定点而易脱落等问题,值得推广。
Objective：In order to identify an easy-operating and more useful arterial catheterization method for students,we compared two kinds of cannulas in the medical functional experiments,one is the traditional homemade arterial catheterization and the other is the straight venous retention needle.Methods：40 experimental animals were randomly divided into two groups （A and B）,the traditional homemade arterial catheterization and the straight venous retention needle （18G × 29MM） were used respectively in carotid artery catheterization.The operating time and successful rate of arterial catheterization were also compared and evaluated.Results：In the experiments,the effects of straight venous retention needle is better than that of the traditional homemade artery catheterization both in operating time and successful rate of arterial catheterization.Conclusion：The traditional homemade arterial catheterization has different caliber sizes and easily to fall off without fixed point,while using the straight venous retention needle is simple,rapid,accurate,safe,and has a high successful rate.As a result,the straight venous retention needle is more suitable for the arterial catheterization and worthy to be widely used in the functional experiments.
