We have the nitrile gloves (purple) and some kind of blue gloves that aren't vinyl or plastic...don't really know what they are. (I'll look when I'm there again.)
To be honest, I don't really care what kind of gloves they give me, as long as they aren't the lunch lady gloves, the el cheapo's, or the to small.
I don't support the ban of latex, here is the reason. I think the diamond grip latex gloves are the best gloves I've ever used. They don't rip, easy to get on, and fit really well. Plus, I have a grip when I go to grab something when the glove is wet. I hate wearing nitrile gloves in the rain or around wet surfaces.
Also, I use latex tourniquets because I think they wrap tighter and seem to hold up better.
Still, I ask if the patient is allergic to anything, including latex...but it has its good points. Plus, they are cheaper then nitrile glvoes, and I'd rather have better drugs or better equipment then to simply have non-latex gloves.
Just my two cents.
