The flush method incorporated the use of a 10 ml syringe to inject the sodium chloride through the access site before and after the blood transfusion.
Because of the small number of central venous catheters in this study, further analysis of flush method for this access device was not possible.
No statistically significant difference existed between the normal saline syringe or infusion flush methods for maintenance of intravenous catheter patency during blood transfusions.
