The Value of PICC and CVC Clinical Application: Systematic Reviews

Objective To systematicly evaluate the randomly-chosen documents published in China about peripherally inserted central venous catheter(PICC) and central venous catheter(CVC) to further analyze the pros and cons of these two inserting methods in clinical application.Methods Use the intervention trial research methods provided by the Cochrane Collaboration net and GRADE3.5.1 software to carry out quality evaluation on all the evaluations existed in the documents.RevMan5.1.2 software was adopted to make Meta-analysis of all data.Results In terms of single catheter the success ratio of PICC was higher than that of CVC and the difference was statistically significant;PICC catheter infection rate was lower than CVC group,;The rate of havig been wrongly strayed into the artery in PICC group was lower than that in CVC group;while an incidence of phlebitis in the PICC group was higher than that in the CVC group;No significant difference was found between the two groups in the incidence of pneumothorax,catheter to detain time,the catheter obstruction,the catheter extrusion,catheter tip the incidence of ectopic,the conduit leakage(P0.05);Catheter time between PICC and CVC showed no statistical difference in need(P0.05).Conclusion This study found that PICC had such good points as high success rate of single catheter,fewer complications,long time of tube indwelling and so on,which could be more widely used clinically,however all the documents included for this study analysis were of low quality,so it was unknown about the adaptability of high level of research to be involved in in the future,and we look forward to further confirmation.
