question: My dad had triple bipass surgery four weeks ago. Following that, the wires broke on the sternum, so that was repaired in another surgery. Several days later, an infection set in and he was taken back to surgery to clean out the infection. That was followed by sternum reconstruction. The infection is gone, but Dad has been in a medically induced coma for 1 1/2 weeks now (since the surgery to clean out the infections). They are trying to take him off the sedation and bring him out of the coma, but each time they reduce the sedation he begins to get agitated and is not yet responding to direct commands. He has also been on a ventilator during this 1 1/2 week. What concerns should we have or questions should we be asking?
