first of all.... hello to everyone out there, I'm new to this site and enjoy it very much.... Now for my question.... When giving SQ heparin injections, what type of syringe do u guys use??? the reason i'm asking is b/c for the last 13 years i've given these inj. with insulin syringes. I've recently switched units (from ortho/oncology/pain mgmt rehab to head injury rehab) and the nurses on this unit tell me that you have to use tb syringes when giving hep. inj. AM I MISING SOMETHING OR WHAT???
