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.
