As a side story. I met an older middle aged man at the grocery store some time ago. Somehow the conversation turned to a car accident he had had. Maybe he had a dialysis fistula I noticed. So the accident. They pumped 15 units or more of blood thru this man. He drained the blood bank. It came to a decision of mismatched blood or no blood at all. If you were the Dr. what would you have done? He lived, instead of being grateful, he sued. and won.
The rules about malpractice are very clear about following standard practice. Unfortunately the jury system we have eliminates anyone who knows anything about the area concerned. Most malpractice suits are BS. IMHO
