静脉留置针安全留置时间的Meta分析

摘要

Objective To explore the optimal retention time of intravenous indwelling needle.Methods Computer retrieval was conducted to search for the relevant published literature,Meta-analysis was used for quantitative aggregate analysis for related articles and confirm the optimal retention time of intravenous indwelling needle.Results After screening,only 9 articles were included in the study.Meta analyses showed that the incidence of phlebitis was obviously reduced venous indwelling needle for 3-4 day than 5-7 days (p<0.01);there was significant difference between the venous indwelling needle for 3-4 day and 5-7 days in decreasing the rate of thrombosis (p<0.01).Conclusion It is safe to stay 3-4 days after intravenous infusion of normal saline.However,searchable database of this study less,it is necessary to find more randomized controlled trials to further confirm this.%目的:探讨静脉留置针的最佳留置时间.方法:利用计算机检索已发表的相关文献,应用Meta分析方法对其进行定量分析评价,确定静脉留置针的最佳留置时间.结果:经过筛选最终9篇文献纳入研究供Meta分析.研究结果显示:静脉留置针留置3-4天对降低静脉炎的发生率较留置5-7天明显(p<0.01);静脉留置针留置3-4天与留置5-7天在降低静脉血栓形成方面的差异具有统计学意义(p<0.01).结论:静脉留置针输入生理盐水后留置3-4天是安全的,但由于本研究检索的数据库较少,有必要查找更多设计严谨的随机对照试验来进一步论证.
