Another thread has me wondering....why cant we return the waste blood back into a PICC. If you cleanse the port with alcohol swab prior to accessing (just as if you were administering a drug) why cant you return the blood? I mean, it would be the same as infusing a med via IV push, except it would be their blood rather than a drug. So how would contamination be an issue? The syrings is sterile, and you flush afterward. Im just wondering because when we draw coags from a PICC, we have to waste 20 ml's...thats ALOT to waste everyday or q 12 hours, especially if they already have a low H&H. Your opinions? ICU here returns it, but they have a special line that they draw it with (Im not sure what its called)
