filter needles

I have never used one in my life (Australia).

I was a traveler in a dialysis unit which had no filter needles. 18g needles were used to draw up the Ferrlicet from the ampules. This practice always really bothered me.

Under search put in filter needles
I guess I exagerated saying 1000s of glass particles...around a hundred but depends on ampule size

When I worked in Canada we never used them.

It is my understanding that filter needles are only required for drawing from a glass amp that you break open.......are they necessary for such things as Solumedrol, or protonix, which have the rubber stoppers?......

as far as the Phenergan, we don't use filters for that however we do mix the Phenergan in 10ml sterile saline before injecting....
