摘要
目的探讨压脉带应用的时间对静脉穿刺成功率的影响。方法将200例采血对象分为观察组(112例)和对照组(88例),两组的年龄、性别构成差异无统计学意义,观察组压脉带压迫时间40-100 s,对照组压脉带压迫时间100-200 s,然后静脉穿刺,计算两组穿刺成功率,并进行比较分析。结果观察组的静脉穿刺成功率(98%)高于对照组(91%),两组间差异有统计学意义(P<0.05)。结论压脉带的应用时间对静脉穿刺成功率有影响,临床应用压脉带时,应减少其应用时间,以提高静脉穿刺成功率。
Objective To explore the effects of different period by using of tourniquet on the success rate of the collection of venous blood samples. Methods 200 subjects were divided into two groups according the different time of application of the tourniquet： test group （n = 112） in which use of tourniquet lasted for40 - 100 seconds, the other control group （n =88） in which the use of tourniquet lasted for 100 - 200 seconds. After venepuncture, the success rate of the collection of venous blood samples was calculated and analyzed. Results The success rate of venepuncture of test group was higher, than that of control group （98% vs. 91%, P 〈 0.05 ）. Conclusion The success rate of venepunture is affected by the period of the use of tourniquet. In order to increase the success rate of venepunture, the time of the tourniquet inflation should be shortened appropriately.
