    once you get the flash, hook a 3cc (no bigger) syringe to the catheter and push a small amount of saling into the vein to *open* it up while you advance it. bigger syringes create too much pressure and blow the vein. works like a charm!!!!!!!
    whoa! that is wrong! the smaller the syringe, the higher the pressures created in the vein. if you're going to do a direct flush of any solution into a vein, your best choice is to use as large a syringe as possible. those 3cc syringes create a lot of pressure.

    Thank you for reiterating my point. I only brought up central lines as an example of why a smaller syringe creates more pressure. Conversely, a smaller syringe creates LESS pressure when apirating blood and might solve you problem during blood draws from central lines.
