i am sorry, prayers being sent. i'm sure he will be fine. but you take care of yourself too. stress will lower your bodies resistance and you don't need to become ill either.
i agree you have to keep an eye things. hospitals move so fast and with so many patients, mistakes can happen. when my dad had to go so often and get blood transfusions, i just happened to look at the bag. it was the wrong blood type. i asked the nurse to double check and it was wrong. he wound up having to get meds to counteract the effects of the wrong type blood. it could have been bad if he'd gotten all of that bag.
