A: Oh wow - I am so sorry to hear all of this. You may have a claim against them - but I am not licensed in NC and cannot advise as to the laws of negligence in North Carolina. If you would like a few excellent attorneys licensed in both VA and North Carolina - I recommend Amberley Hammer (Va Beach) or Fred Smith (Martinsville). Both can advise on a NC case. I wish you all the best, and am so sorry to hear what has happened.
A: Dear one - I am so sorry for this bad news.
I would have a meeting both with the hospital risk management (where you do mostly listening as to what happened) and call an attorney in your area experienced in Medical Malpractice work.
I will be thinking of your family and will say a prayer for your brother.
