RESUMO
Objective:To search, evaluate and summarize the evidence related to the maintenance of peripheral arterial duct flushing systems in children for clinical reference.Methods:Up To Date, BMJ, Nathional Institute for Health and Care Excellence(NICE), Chinese Medlive, Cochrane Library, Joanna Briggs Institute(JBI), CINAHL, METSTR, PubMed, Wanfang, CNKI, VIP were used to collect secondary evidence resources about management and maintenance of peripheral arterial duct flushing systems in children. After the quality evaluation of each type of literature, the evidence was extracted and summarized.Results:A total of 9 articles were included in the research. The 22 pieces of best evidence were obtained from 7 aspects, including basic requirements of children′s peripheral arterial duct flushing systems, arterial flushing method, flushing rate of injection pump system, flushing pressure of pressurized bag pump system, arterial flushing fluid, replacement and maintenance of children′s arterial catheter flushing system, and continuous improvement of arterial catheter maintenance.Conclusions:The best evidence for the establishment and maintenance of pediatric peripheral arterial duct flushing systems provides a basis for clinical decision, but practice testing is still needed.
