足背动脉采血两种不同进针角度效果研究

目的:通过观察传统法与垂直进针法行足背动脉采血的临床效果,找出更适合足背动脉采血的方法。方法:对200例病人随机分组,采用15°-20°角进针法(对照组)和垂直进针法(观察组)行足背动脉采血,观察两组一次穿刺成功率和皮下淤血、瘀斑发生率。结果:观察组一次穿刺成功率高于对照组,皮下淤血、瘀斑发生率低于对照组,差异有显著性(χ2=9.191、6.438,P<0.05)。结论:垂直进针法行足背动脉采血可提高一次穿刺成功率,降低皮下淤血、瘀斑发生率,值得在临床护理工作中推广。

Object To observe the clinical effect of dorsalis pedis artery blood collection with puncturing by traditional method or punctu- ring by right angle Methods 200 patients were assigned randomly to the test group （ puncturing by right angle） and the control group （ punctu- ring by 15° -20°angle） , then we observe the two sets of a puncture success rates and rates of congestion, ecchymosis occurs under the skin. Results Tile one - time success rate of puncture in the test group was obviously higher than that in the control group（ P 〈 0. 05 ） ; Cutaneous congestion, ecchymosis incidence is lower than in the control group, differences are significant （χ2= 9. 191,6. 438 ,P 〈 0. 05 ）. Conclusion Dorsalis pedis artery blood collection with puncturing by right angle may improve the success rate of one - time puncture, reduced subcutaneous congestion, incidence of ecchymosis, worthy of popularization in clinical nursing.
