单手指固定法在桡动脉采血中的应用

Application of A Single Finger Fixation in Blood Collection from Radial Artery

目的探讨单手指固定法行桡动脉采血的临床效果。方法选择240例需行桡动脉采血进行血气分析的患者,随机分为对照组和观察组,每组120例。对照组采用两手指固定法采血,观察组应用单手指固定法采血,观察2组患者的采血效果、采血成功时间、一次采血成功率、采血后局部血肿情况、疼痛程度。结果 2组的采血效果差异无统计学意义(P>0.05);观察组一次采血成功率显著高于对照组(P<0.05),而采血成功时间、血肿发生率、疼痛程度明显少于对照组(P<0.05)。结论单手指固定法采集桡动脉血气标本时间短、血肿发生率低、疼痛程度轻。

[Objective]To investigate clinical effects of a single finger fixation in blood collection from radial artery. [Methods]A total of 240 patients,who needed blood gas analysis from radial artery,were randomly divided into control group and observation groups,120 cases in each group.Two fingers fixation was used in control group in blood collection from radial artery,while the observation group received a single finger fixation.The blood collection effect,the time of puncture,the one-time-success rate of puncture,local hematoma incidence and pain degree were observed in 2 groups. [Results]There was no significant difference in the blood collection effect in 2 groups（P0.05）.The one-time-success rate of puncture in the observation group was significantly higher than that in control group（P0.05）,while the time of puncture,the incidence of local hematoma and the degree of pain were significantly lower than those in the control group（P0.05）. [Conclusion]A single finger fixation in blood collection from radial artery has a shorter collection time,lower incidence of hematoma and less pain.
