循证护理对减少或预防患者 PICC置管并发症的M eta分析

目的：综合评价循证护理对减少或预防患者经外周静脉置入中心静脉导管（PICC ）置管并发症发生的应用效果。方法计算机检索中国知网、万方数据库、中国生物医学文献数据库、VIP资源，Pubmed数据库，收集国内外应用循证护理的方法减少或预防PICC置管并发症的随机对照研究，采用RevM an 5．0软件对符合纳入标准的随机对照研究进行M eta分析。结果共纳入17个随机对照研究，3092例研究对象。研究结果显示，循证护理组患者PICC置管并发症（静脉炎、穿刺点感染、导管脱出或异位及导管堵塞）发生率明显低于对照组（P＜0．05）。结论循证护理可有效减少或预防PICC置管并发症的发生，提高护理质量的同时改善PICC置管患者生活质量，值得在临床上推广应用。

Reduce and prevent effect of evidence based nursing on the complications of patients with PICC:a Meta analysis

Objective To evaluate the effect of evidence based nursing on the prevention of the complications of PICC .Meth‐ods The randomised controlled trials (RCT) on the evidence based nursing in reducing or preventing the complications of patients with PICC were collected using the databases of PubMed ,CNKI ,WanFang ,CBM and VIP;the data were analyzed by RevMan5 .0 software .Results 17 studies involving 3 092 patients were included in total .The results of Meta analyses showed that compared with the control group ,the complication (Phlebitis ,puncture point infection ,catheter prolapse or ectopic and catheter obstruction) rates of evidence based nursing group with PICC were lower (P<0 .05) than that of the control group .Conclusion Evidence based nursing can effectively prevent the complication of PICC ,improve the quality of nursing and worth of clinical application .
