手指触觉训练有助于提高浅静脉穿刺成功率

目的探讨手指触觉灵敏性与静脉穿刺的关系，以提高学员的浅静脉穿刺成功率。方法通过204人拇指和示指对血管感知灵敏性的对比，找出较灵敏的手指；将144名受训学员随机分为实验组（模拟练习中增加手指触摸血管训练法）和对照组（传统教学）各72人，比较两组学员的静脉穿刺成功率。结果96．1％的学员认为拇指桡侧端对血管的感知更灵敏；实验组采用手指触觉训练法，穿刺成功率高于对照组采用的传统教学法，两组比较有统计学意义（P〈0．05）。结论手指触觉训练可开发手指皮肤的触觉灵敏性，提高静脉穿刺成功率。

Finger Tactile Training Improves the Successful Rate of Superficial Venipuncture

Objective To investigate the relationship between the sensitivity of finger tactility and the successful rate of superficial venipuncture,so as to improve the venipuncture successful rate.Methods The more sensitive fingers were identified by comparing the sensitivities of veins between the thumbs and the index fingers in 204 subjects.A total of 144 trainees were randomized into experimental group(n=72,received finger tactile training) and control group(n=72,received routine teaching).The successful rates of venipuncture were compared between the 2 groups.Results The venipuncture successful rate was significantly higher in trainees of the experimental group who received finger tactile training than in those of the control group(P<0.05).Conclusion It is concluded that the skin sensitivity of finger tactility can be developed by finger tactile training,and therefore improve the successful rate of venipuncture.
