Our OB unit has recently begun giving the hep B vaccine to our newborns prior to discharge if the parents elect to have it. We recently discovered that we are not all administering it with the same size needle. What do you feel is appropriate for an IM injection in a newborn, both guage and length? The research I've done states 7/8 to 1 inch in length but all the nurses I work with are shocked at this, and it does seem kind of long, however some are giving it with a TB syringe which I think is way to short for IM. Any thoughts?
