I would like to know how others are defining maximal barrier precautions for CVAD insertion in terms of the gown for the assistant. I know the assistant MUST wear a bonnet and mask and I believe a non-sterile gown if they are close to the sterile field. Others believe they do not need to wear a gown. This assistant is within 3 feet of the field,adding on sterile items,prepping the arm and reaching by the field to release the tourniquet and even holding the patient's arm under the sterile drape. Happy for any advice!
