There are two types of heart valve replacement surgery: median open heart and right side open heart with a small incision. Median open heart surgery tends to hurt for 3 to 7 days after surgery. The right side small incision thoracotomy does not require any sawing of the ribs or sternum. However, it will hurt for about a week after the surgery due to the impact of the retractor on the ribs during the surgery. Traditional open heart surgery requires cutting the sternum and then fixing the sternum with a wire tie after the surgery, which is a relatively large surgery, and the wound will inevitably be painful after the surgery, and the wound will usually be painless for about a week after the surgery. If the patient is sensitive to pain, the patient can use the chest strap for external fixation under the guidance of professional doctors, which can stabilize the sternum and reduce the pain of the wound. After heart valve replacement surgery, it is recommended to take anti-inflammatory drugs in strict accordance with the doctor’s instructions, and cooperate with the follow-up treatment to promote recovery. If the pain is intolerable, timely feedback should be given to the attending physician, appropriate pain medication should be taken, and pain injections should be considered if necessary. Postoperative diet should be light, do not eat spicy stimulation or too greasy food, pay attention to rest, regular review.
