The recuperation activities and review of patients after discharge: 1, generally need to rest for 6 months after flap replacement, during the rest period, you can take a walk, light housework activities, should gradually increase the amount of activity, in order not to feel tired. 2, after discharge from the hospital to maintain a happy mood, maintain an optimistic and positive attitude and firm belief, can participate in some relaxing recreational activities, do not be impatient and worried, to facilitate a faster recovery. 3, after the extracorporeal circulation surgery may be some mental and emotional changes and memory loss, most patients will soon disappear, no need to worry. 4. Although the skin incision heals after surgery, the sternum takes a long time to heal (about six months), so heavy physical activities cannot be performed. As the body recovers, some patients may feel muscle tension or even pain in the neck, shoulder and chest, which requires light activity and will improve after gradual functional exercise. 5. Six months after discharge from the hospital, it is necessary to go to the hospital for a review. At this time, the heart function gradually improves, and the post-surgical effect can be evaluated. If you encounter the following conditions, you should go to the hospital for review in time: (1) chest pain instead of incisional pain. (2) Below 60 beats/minute or above 120 beats/minute. (3) The presence of heart rhythm disturbances, such as frequent premature ventricular beats, paroxysmal supraventricular tachycardia, irregular heartbeat or pulse. (4) Persistent high fever of 380C or higher, or infection. (5) Edema in the lower extremities, sudden weight gain, shortness of breath, panic, shortness of breath, coughing up foamy sputum. (6) Nausea and vomiting with no obvious cause, yellow sclera and skin staining, etc. (7) Sudden syncope, coma, hemiparesis, aphasia or pain in the lower limbs, chills, pallor, etc. (8) Bleeding phenomena such as subcutaneous bleeding, hematuria and black stool. (9) Other obvious illnesses. 6.Prosthetic valve failure can lead to very serious consequences, the following symptoms should be promptly sought, such as 2 or more to be considered as prosthetic valve failure, if necessary, need to revalve surgery: (1) the progressive emergence of low heart sound and heart murmur. (2) Sudden deterioration of cardiac function that cannot be controlled by medication. (3) Embolism of the brain, kidneys, intestines and extremities. (4) Severe hyperthermia with confirmed diagnosis of infective endocarditis. (5) Presence of hemolysis, manifested by progressive anemia, hematuria, etc. (6) Echocardiography proves poor prosthetic valve mobility or thrombosis. (7) When the patient has an irregular heartbeat, he should rest and go to a nearby hospital for ECG examination. If it is atrial premature beats, it can be controlled with adequate rest and cardiac stimulants such as digoxin, etc. If it is ventricular premature beats, it should be controlled with drugs as early as possible, and at the same time, the cause should be actively sought to see if there is hypokalemia, hypotension, etc. to treat its root, and other types of arrhythmias should also be controlled in time. 8, should actively anti-rheumatic treatment, mainly using long-acting penicillin intramuscular injection or enteric aspirin oral treatment. 9.Sexual life should be abstained, and at the same time, attention should be paid to avoid pregnancy. If there are special circumstances, pregnancy should be considered after good recovery of cardiac function. 10.For those who developed atrial fibrillation within 3 months before surgery, atrial fibrillation can be removed after surgery as long as the cardiac function is well maintained. Pre-operative atrial fibrillation is longer, because patients are more adapted to atrial fibrillation, even if atrial fibrillation exists after surgery, it has little effect on cardiac function and can be left untreated. If atrial fibrillation is still present after cardiopulmonary diuresis and the patient is not adapted to it, the patient can be treated with drug defibrillation or electric defibrillation in the hospital six months after the operation when the cardiac function improves significantly. For those with stubborn atrial fibrillation, the heart function is poor, so do not forcefully correct the fibrillation to avoid danger, but should be treated with cardiac diuresis. 11, cardiac function is an indicator of the degree of the patient’s pathology. According to the preoperative and postoperative changes in cardiac function, the effect of treatment can be clarified. In conclusion, after valve replacement, although the patient’s symptoms are significantly improved, in order to maintain good cardiac function, keep the normal operation of the prosthetic valve, and prevent various post-valve replacement complications, it is important to insist on regular follow-up and keep in touch with the doctor to facilitate timely detection of problems and timely treatment.
