Quick question on the push-pause turbulent flow technique of flushing PICC's - I believe there has not been any research base for this technique but it is common practice. In theory it is creates more turbulent flow of saline in the catheter which helps clear the catheter of blood, medication etc.
Recently, the push- pause technique was brought up by a product rep for TPA - who suggested that turbulent flush caused the PICC tip to whip back and forth which helps keep the catheter free of fibrin. Has anyone else heard this explanation? - Catheter tip movement like this could injure the wall of the vein - does anyone know if this is actually occuring with turbulent flushing?
