摘要
目的运用荟萃(Meta)分析评价老年人外周浅静脉留置针用生理盐水封管与用肝素钠封管的效果。方法采用Cochrane系统评价的方法,计算机检索中国知网(CNKI)、维普和万方数据库,查找比较生理盐水与肝素钠封管的随机对照试验(RCT),对纳入的随机对照试验进行质量评价并提取有效数据,采用RevMan 4.2.10软件进行Meta分析。结果共纳入10项随机对照试验,合计1 126例患者。Meta分析结果显示,肝素钠封管在静脉留置针留置时间方面优于生理盐水封管,差异有统计学意义;在堵管发生率和静脉炎发生率方面比较,差异无统计学意义。结论本系统评价结果显示,肝素钠封管延长留置时间方面优于生理盐水,在预防堵管和静脉炎的发生方面比较,差异无统计学意义。
Objective To compare the effects of two kinds of sealing solutions in elder patients with venous in- dwelling needle. Methods The comprehensively and systematically bibliographic search of medical literatures from databases of CNKI, Weipu and Wanfang was conducted to identify randomized controlled trials （RCTs） re- lated to catheter sealing with saline vs. heparin sodium. The remaining time of venous needle, incidence of phlebitis and catheter blockage were compared, the quality of RCTs was assessed and meta-analyses were con- ducted by RevMan 4.2.10 sotfware. Results Ten RCTs involving 1 126 patients were included. The results of meta-analyses showed that the average remaining time of venous catheter sealed with heparin sodium was longer than saline. There were no significant differences between saline sealing and heparin sodium sealing in the inci- dence of catheter blockage and phlebitis. Conclusion The meta-analyses of current medical literatures show that heparin sodium sealing can prolong the remaining time of catheter, although there are no significant effects on the incidence of catheter blockage and phlebitis.
