探讨改良静脉输液排气法对提高静脉穿刺成功率的影响

目的:探讨通过改良静脉输液排气法,提高静脉穿刺过程中穿刺针头肉眼可见的回血率,从而达到提高静脉穿刺成功率。方法:将3120例静脉穿刺患者按年龄段随机分为实验组与对照组,每组1560例。实验组采用常规输液排气,进针前再次排气时采用改良的静脉输液排气法排气后静脉穿刺;对照组采用常规输液管排气后静脉穿刺。结果:实验组与对照组穿刺针肉眼可见回血及一次穿刺成功率方面比较,差异有统计学意义(均P<0.005),实验组在穿刺针肉眼可见的回血率及一次穿刺成功率方面均高于对照组。结论:提高静脉输液排气技巧,可提高穿刺针肉眼可见的回血率及一次穿刺成功率。(上接95页)夹轮,使穿刺针斜面充满液体,并在穿刺过程中始终保持针头斜面充满液体[4,5]。笔者认为此种排气方法适用于所有静脉输液的排气。

Objective：To study the method and results in enhancing the vein puncture success rate,by improving exhanstible way of vein transfusion and increase return blood can see of infusion needle in the vein puncture. Methods：The 3120 patients who need the veins puncturing were divided into the experiment group and control group followed different age randomly, 1560 cases in each group. Patients in the experiment group were applied general exhanstibie way of vein transfusion, when exhanst again before puncture, using improving exhanstibie wey of vein transfusion after using vien puncture; control group using general exhanstibie way of vein transfusion after using vien puncture. Results ：There are some differences between the two groups in rate of return blood can see in infusion needle and the success rate of single vein puncture （P〈0.005）. Compared with the control group, the experiment group has higher success rates either in return blood can see in infusion needle or in single vein puncture. Conclusion：The method of improving exhanstible wey of vein transfusion can improve the success rate of return blood can see in infusion needle and single vein puncture.
