SDN Members don't see this ad. (About Ads) It was a 2 gm Ancef in 100 mL NS. She used 2 different manufacturers (6 x 1gm vials) My concern is that I don't know which bag has which manufacturer? So in case of an adverse event, I would rather track the bag to one manufacturer. What do you guy think? Should I just use the bags or have her remake them with one manufacturer per bag !?
