When using a central venous line, I have many questions....at your facilities, 1. What type of central lines are you using (Groshong, Broviac, etc....) 2. What population/s do you use them for? (Pediatric, Adult, etc...) 3. When you give chemotherapy, what size syringe do you use when giving the medication through the central line? I would like to know general chemo and specifically Vincristine. 4. Do you give the chemotherapy with a syringe pump or push? Thanks.
