婴幼儿静脉留置针留置方法研究

Analysis of methods of preserving needle in infant

目的 探讨婴幼儿静脉留置针留置方法。方法 将 10 0例婴幼儿随机分成两组 ,采用改进法为观察组 ,75例 ,运用常规方法为对照组 ,2 5例。结果 两组婴幼儿静脉留置针成功率经 χ2检验 ,χ2 =15 .5 9,P<0 .0 1,留置时间经 t检验 ,t=36 .3,P<0 .0 1有显著性差异 ;塞管、局部发红情况经χ2 检验 ,P>0 .0 5 ,无显著性差异。结论 小于 10°角进入皮肤 ,浅而渐深进入血管 ,回血后送软管为可行的婴幼儿留置针穿刺方法 ;高浓度肝素一次性封管既可减少工作量 ,也能长时间地维持软管通畅。增加必要措施 ,做好陪护健康教育成为婴幼儿固定留置针重要的一关。

Objective To determine the effective method of preserving needle in infant. Methods 100 cases were randomly divided into two groups: 75 in experimental group and 25 in control, receiving improved and normal preserving method respectively. Results It was showed that there was significant difference (P<0.01) in success rate in preserving venous needles in the 2 groups. There existed also significance in time span of preserving venous needles (P<0.01). But there was no significance in ductus obstruction in the 2 groups during preserving venous needles (P>0.05). Conclusion It may be a good method for preserved needle to be punctured into at an angle of less than 10 degrees and into vein gradually, and then be replaced with soft dutus when blood was seen in needle. Sealing the soft dutus with high-concentrated heparin not only frees nurses from hard work, but keeps the dutus smooth. Necessary nursing and health education of the infantile companies are key to preserving needles in infant.
