目的探究肝素和局部热敷在预防静脉留置针血栓方面的疗效,为护理工作者在制定静脉留置针血栓预防措施提供科学依据。方法计算检索获得肝素和局部热敷在预防静脉留置针血栓方面的文章,用RevMan 5.1软件对相关研究进行meta分析。结果最终纳入4篇文献,总计1474例患者,其中肝素和局部热敷组(试验组)736例,0.9%生理盐水组(对照组)738例。本例中合并效应量落在无效线的右侧,试验组更有利于预防静脉留置针血栓的形成[OR=2.80,95%CI=(2.27,3.47)]。漏斗散点图大致呈对称漏斗状,表示不存在偏倚。结论使用肝素和局部热敷的效应量大于生理盐水的效应量,因此在使用肝素和局部热敷进行静脉留置针封管时,可以有效的预防静脉留置针血栓的形成。
Objective To explore the curative effect of heparin and local hot compress in the prevention of thrombosis of venous indwelling needle and provide scientific basis for nursing workers to make preventive measures of venous indwelling needle thrombosis. Methods To calculate and retrieve articles that obtained heparin and local hot compress in the prevention of venous thrombosis, and meta-analysis of related studies using RevMan 5.1 software. Results Finally, 4 articles were included in the study, totaling 1474 patients, including 736 cases of heparin and local hot compress (experimental group) and 738 cases of 0.9% saline (control group). In this case, the amount of combined effect falls to the right of the ineffective line, and the experimental group is more conducive to the prevention of venous thrombosis [OR = 2.80,95% CI = (2.27,3.47)]. Funnel scatter diagram roughly symmetrical funnel, said there is no bias. Conclusion The effect of using heparin and local hot compress is greater than that of saline. Therefore, the use of heparin and local hot compress to seal the venous catheter can effectively prevent the formation of venous catheter thrombosis.
