外周静脉留置针脉冲式和直接推注式封管效果的Meta分析

Effectiveness of pulsative flushing and continuous flushing for peripheral venous catheter:a Meta-analysis

目的评价外周静脉留置针脉冲式和直接推注式封管的应用效果。方法计算机检索Cochrane图书馆、ProQuest、PubMed、Webofscience、Ovid、Embase、CINAHLcomplete(EESCO)、中国期刊全文、万方、维普及生物医学文献数据库并收集外周静脉留置针应用脉冲式和直接推注式封管效果的随机对照试验和半随机对照试验,采用Revman5.3软件进行Meta分析。结果共纳入13项研究,共1679例患者。Meta分析结果显示2组在降低堵管率(P<0.01)、留置时间(P<0.01)差异有统计学意义,在降低静脉炎方面2组差异无统计学意义(P<0.05)。结论脉冲式封管较直接推注式封管更有效降低堵管率、延长留置时间,在降低静脉炎方面两者差异无统计学意义,但对于心血管疾病患者须慎用脉冲式封管。

Objective To evaluate the effectiveness of pulsative flushing and continuous flushing for peripheral venous catheter.MethodsBy retrieving Cochrane Library,ProQuest Research Library, PubMed,Web of science,Ovid,Embase and CINAHL eomplete(EESCO),China National Knowledge Infrastructure(CNKI),Wanfang,Weipu,and China Biology Medicine disc(CBMdise)to find the randomized controlled trials(RCT)and clinical controlled trials(CCT)that been applied to compare pulsative flushing and continuous flushing for peripheral venous catheter,and using Revman5.3soft for a Meta-analysis.ResultsThere were thirteen studies which had involved1679patients.The Meta- analysis'results as follows:The pulsative flushing was superior than continuous flushing indeereasing intravenous catheter's blockage(P<0.01),and had prolonged more time than continuous flushing in retaining catheter(P<0.01).The two flushing methods were similar in reducing phlebitis(P>0.05). ConclusionsThe pulsative flushing was superior to the continuous one in reducing the intravenous catheter's blockage and prolonging the catheter's times.There were similar in decreasing phlebitis.The pulsative flushing method was used with caution in chronic,diseases such as angiocardiopathy.
