EMLA is a brand name for a cream that is used to numb the site of the blood draw. It is 2.5% lidocaine and 2.5% prilocaine. For us, it required a prescription and came in a 5 gram tube. We put it on the site we thought they would draw blood from, then covered it with an "occlusive dressing" (one brand name of dressing is Tegaderm). I think the EMLA really does numb the area. When Jack got his immunization shots I held him on my lap, facing me, with his legs around my waist. The nurse gave him the shot in his leg, he didn't see it, and he didn't even flinch. However, the lab techs who draw blood in this area don't like EMLA because they say it constricts the blood and makes the draw more difficult. We also had the problem of knowing where to put the EMLA. They usually had to try so many different veins and I didn't want to cover his whole body in the stuff. Hope that helps - and hope your little one is doing well. - Chris
