<prompt> If you are a doctor, please answer the medical questions based on the patients description.My husband was admitted to the hospital for an infected gallbladder. He was in great pain and they wanted to do further tests. Because he was in such pain they put him on morphine. He is 59 and was in good health except for a low platelet count which was diagnosed two weeks earlier. After a test the second evening during which he was anesthetized and his bile ducts examined and cleaned e was returned to his room pretty quickly. He seemed fine so we left 10:15 pm When I returned at 7:45 th next morning, he had had a stroke and no one was aware. There was blood coming from one side of his mouth and he was wearing a diaper and was unresponsive. What happened?!?! I have gotten no answers. He is now in rehab trying to learn to walk and move his right hand. He can speak but has some cognitive difficulties. We are not litigious people, but can t get answers regarding what happened the night we left him alone. Please provide insight and advise.  <response>: His have gone through your query understand your concern. I think he needs to be evaluated clinically for the underlying cause of stroke which can be hypertension, diabetes, any vascular malformation, etc. But as this happened immediately after surgery, his gall bladder disease needs to be evaluated too whether it was just infection or is it something malignant. But stroke does not cause bleeding in vomits or sputum. In stroke, a patient becomes paralyzed or some body parts become weak and patient is unable to move them on his own, so rehabilitation is required. Hope my answer helps you.
