Hi, Yeah, the hand closest to the patient is your dirty hand and the one closest to your sterile field is the clean one. The dirty hand is the only one that touches your patient and vice versa. From what I understand, the point of ANTT is that you do not touch the sterile part of the dressings at all. The way it was explained to us was that as soon as the sterile pack is opened, it's no longer sterile therefore it is ANTT is advocated. Hope this helps!
