What do we know about flushing for intravenous catheter maintenance in hospitalized adults?

Abstract

Objective: to evidence the use of flushing to prevent complications from intravenous therapy. Methods: an integrative review in databases, using descriptors and selection criteria. Data were collected in 12 articles using an instrument and later classified, summarized and aggregated for knowledge synthesis. Results: it was evident that: the pre-filled syringe resulted in a lower occurrence of catheter obstruction; irregular flushing frequency caused advanced phlebitis; the use of Venous Arterial Blood Management Protection (VAMP) generated a lower incidence of blood infection; heparinized solution did not result in a lower central catheter failure rate; flushing volume and frequency were not predictors of catheter failure; flushing practice was not shown to be incorporated among professionals. Conclusion: there are disagreements about the volume, frequency, solution and devices used in flushing. New technologies can reduce complications such as obstruction and infection.

Flushing in Intravenous Catheters

“…16,17 In addition, an integrative literature review of publications on flushing between 2016 and 2020 did not identify research carried out in the Brazilian context on flushing in this period. 18 This shows that, in Brazil, there is a lack of research on the topic. Therefore, there is a need for more evidence on implementing flushing at the national level, with a view to adopting strategies that strengthen its practice among professionals and increase patient safety.…”

“…In Brazil, existing research has generically evaluated the practice of flushing, that is, only verifying whether it is performed as one of the stages of administration of intravenous therapy without a more profound examination of the characteristics of this practice and the factors associated with its application 16,17. In addition, an integrative literature review of publications on flushing between 2016 and 2020 did not identify research carried out in the Brazilian context on flushing in this period 18…”
