Size matters!

[dsgrandmarn]

I need help! In my new position I give a lot of IV meds but since my orientation ended I've gotten confusing info about correct syringe sizes to use with saline locks and central lines. Could I hear from others on this? What size syringe for flushing and actual injection of med into line for central lines and saline locks? During orientation my preceptor used 10 cc for everything but now I see and read conflicting info. So far I've had no trouble with this but it worries me and I want to do it right. Thanks!

10ml syringes for the central lines-they create less psi in the lumen during the flush and won't rupture t he catheter. Smaller syringes can be used for peripheral IV's (3's or 5's),but a 10ml would do no harm.
