Heart surgery is different from other surgeries, and there is a certain amount of psychological pressure for patients and their families. First of all, we should have a correct understanding of the disease, heart disease is different from cancer, most of them can be cured, and the healing effect is better. However, if the disease is not treated for a long time, it can lead to heart failure and heart rate disorders, which can be life-threatening. With the development of modern medicine and technology, most of the cardiac surgeries are routine and have a high success rate. After the patient enters the operating room, he or she sleeps under general anesthesia and then operates without pain or fear. Therefore, patients should be assured of treatment. Before the surgery, the doctor should carry out the functional examination of the human body systems. Patients should do a good job of personal hygiene, the bathing time should not be too long before the surgery, prevent cold, flu and fever, the diet should be easy to digest, high protein rich in vitamins, and should not drink too much water. Patients with heart disease are weak, pay attention to dietary hygiene, fruits such as bananas and apples should not be eaten, such as causing gastroenteritis can aggravate cardiac insufficiency. We have met patients who lost their lives because of this before surgery. It is important to ensure adequate sleep and rest. In addition, some exercises should be performed, such as coughing after deep inhalation, urinating in bed and other exercises. After cardiac surgery, you need to be ventilated with tracheal intubation for a period of time, during which you cannot speak, but there is no too much discomfort. Before the operation, explain to the patient that if there is any request, you can sign or write it out with a pen, and never speak or spit out the tube, because this can cause damage to the throat and aggravate the pain. Financially, prepare according to the average number of doctors, and then prepare a part of the mobile expenses, because each patient’s postoperative recovery is different. The patient’s family should know their condition, whether it is common or rare, mild or severe, complex or simple deformity, low risk or high risk treatment and cure rate, the natural course of the disease and its consequences, so that they can have an idea, weigh the pros and cons and make a decision.
