Dad was two month shy of 96 years old. Last Tuesday he fell in his apartment and broke his hip. The surgery went beautifully the surgeon said and the biggest obstacle was whether he could rehab and walk with a walker. It was very stressful in the hospital, morphine gave him hallucinations. He was very confused and agitated. We got him move to the rehab facility Saturday evening and my sister and I stayed with him until late at night to make sure he was settled. We left and the next morning they dressed him and brought his breakfast and when the went in ten minutes later he was unresponsive. We have no idea what happened because except for his confusion his physical state was ok. They did an autopsy but at 95 it could be almost anything.
