Talk:Winged infusion set

could someone expand on this please.

I'm pretty sure that the reason that it is not recommended for use with sodium citrate tubes isn't because blood remains in the line but rather because there is air in the line to begin with, meaning that the tube vacuum partially fills with that air resulting in a short draw. —Preceding unsigned comment added by 67.132.207.237 (talk) 18:42, 2 November 2007 (UTC)

Butterfly needles follow the same gauge guidelines that other needles follow. The needles aren't inherently smaller. The length is the only thing that is (normally) smaller than regular venipuncture needles, usually 3/4". Block quote Since a butterfly needle doesn't pull quite so hard, and the needle is smaller, the blood flows more slowly in most cases, which can reduce the chances of delicate veins collapsing The needle doesn't "pull", the vacuum on the tube or the suction from the syringe pulls.

Third paragraph—"false" impressions
How is a belief that butterfly needles are less painful and easier on veins really a false impression? It is acknowledged in the article that, although the use of fine needles is less painful, other considerations make the use of fine needles problematic. So the "lay" person's supposed impression is, after all, true. It just may be that, despite the benefit of using fine needles, in terms of reduced discomfort, there exist good reasons not to use them. In any case, the original "impression" appears to be true. Anybody else support this interpretation? Aboctok (talk) 23:09, 14 July 2010 (UTC)
