Open-heart surgery is a relatively high-risk surgical procedure, and post-operative infections are usually from the incision and not usually from the bone. Open heart surgery is open surgery, a collective term for chest surgery by surgically opening the chest cavity or the mediastinal portion of the chest cavity in the middle of the chest, mainly including median open heart surgery, posterior lateral open heart surgery, minimally invasive open heart surgery and other methods. Improper postoperative care may lead to infection and suppuration of the incision, mainly manifested as local redness, swelling, heat and pain, which may be hazardous to health if not controlled in time, but generally will not affect the bones. It is recommended to pay attention to personal hygiene and wound care after the operation, avoiding water infection. Once there is redness, swelling, heat and pain, you need to go to the thoracic surgery department of the hospital in time, and cooperate with the doctor for further treatment.
