hello! just need a comment on this topic. i happened to be preceptoring a newly graduate rn on a medsurg floor. one of my co worker happens to have a piccline draw for the morning and since we dont have any picc line draw on our group, I happened to pick her patient. this patient has a double lumen picc line and has iv fluids running. we stopped the infusion for 5 minutes and flushed the line with with 5 cc Normal saline and discard 8 cc of blood , and draw the blood needed for am labs, we flushed the line again with 8 cc of normal saline (in our facility we dont used heparin) and connect the tubing back to the port. Our coworker started yelling at us coz we used normal saline with ampho b running on the site. IS this going to be a problem ? shes freaking out and running her mouth off for not thinking that saline doesnt go with AMPHO B. any comment will be appreciated... thanks!
