Abstract: Objective To retrieve,appraise and summarize the best evidence of the insertion and maintenance of peripheral arterial catheterization among adult ICU patients. Methods We searched literature from the Registered Nurses' Association of Ontario（RNAO）,National Institute for Health and Care Excellence（NICE）,Scottish Intercollegiate Guidelines Network（SIGN）,Guidelines International Network（GIN） and Chinese Medive etc.,coupled with database search including PubMed,CINAHL,Embase,UpToDate,Joanna Briggs Institute（JBI）,CNKI,WANFANG to collect relevant guidelines,evidence summaries,recommended practice,and expert consensuses. The timeframe of data search ran from the inception of the databases to September 2019. 3 researchers evaluated the quality of the literature independently. With the help of external experts,eligible literature was selected for analysis. Results Totally 13 articles were selected,including 1 clinical decision,3 guidelines,7 evidence summaries,and 2 expert consensuses. Finally,27 items of best evidence were synthesized into 10 categories including education & training,catheter selection,catheter insertion and auxiliary technology,catheter label,skin sterilization and aseptic technique,dressing selection and replacement,transducers,pressure monitoring system,flush solution and replacement time. Conclusion This study summarized the best evidence for insertion and maintenance of peripheral arterial catheterization,and added supplemental evidence to standardize the management of arterial catheter in clinical practice,which may reduce the incidence of catheter-related complications and ensure the security of patients.
