We teach our students that if the catheter is over 3" in length, use no less than a 10cc syringe to ascertain patency. DD

Hi there,

For a saline lock (or whenever administering meds through a peripheral line) that is just that, a peripheral saline lock ( 3" or less), I always use 5ml syringes both for the flush, and for the med ( I always dilute my meds in saline, unless contraindicated).

For saline locks with a catheter > 3" (in which it becomes a midline or central line), we always use 10ml syringes just like Binkey (above) does.

[cannulation]

At our hospital we have ported cannulas peripheral, on which we use no less than a 10ml syringe, unless we have a smart site on (needle free access device, that has a short line that conects to the end of the cannula) which means we are not using the port and so can use a 5ml syringe. For all our midlines and central lines minimum size is 10 ml due the the pressure created by smaller syringes. I work in a hospital in the UK.
