The first three months after heart valve replacement surgery is an important phase in overcoming the trauma of the surgery and recovering from it, and special attention should be paid to daily care and many things during this period. The following are some of the things that should be paid attention to: living and living: Generally, patients can be discharged 2 weeks after valve replacement and go home to rest and recuperate. After discharge from the hospital, patients can gradually resume their personal eating habits, control water consumption appropriately in the early postoperative period, and avoid alcohol abuse and smoking. With the gradual recovery of cardiac function, you can get out of bed every day and move around the house for a while, and then go outdoors for a while, and later you can take a walk and gradually increase the amount of activity to the extent that you do not feel too tired. After six months, the hospital will review the heart function and gradually resume work according to the recovery of heart function. Maintenance of heart function: 1, after valve replacement, due to the improvement of hemodynamics, most patients recently feel good about themselves and symptoms disappear, but in fact, the improvement of heart function, there is still a process, generally about 6 months, a few patients need more than 1 year. During this recovery process, cardiac function should continue to be supported to avoid factors that increase cardiac load. 2.Digoxin should not be stopped abruptly after valve replacement, but should be taken for a period of time, and the dosage should be in accordance with the doctor’s prescription at the time of discharge, generally half a tablet per day. When the heart rate is less than 60 times/minute, it may be digoxin poisoning phenomenon, at this time should reduce the amount and add slow-release potassium tablets. Cardiac stimulants and diuretics should be taken for 6 months, and the dosage should be gradually reduced according to the review situation. Before stopping the medication, you must go to the hospital for a review, and you should not stop taking them at your own discretion. Infection and rheumatic activity control: After valve replacement, especially in young patients, there are still recurrent rheumatic activities. Repeated rheumatic activity is still a serious threat to the patient’s heart muscle and other valves. Therefore, attention should be paid to prevention and treatment, including prevention and treatment of hemolytic streptococcal infections and upper respiratory tract infections. Once an acute attack of rheumatic activity occurs, active medical treatment should be given. If cardiac function is affected by myocarditis, hospitalization should be provided. If tooth extraction, urethral dilation, urinary catheterization, colonoscopy, skin boils, tonsillitis or pharyngitis are performed, antibiotic treatment should be applied promptly to prevent the occurrence of infective endocarditis. Pay attention to the following points: (1) Continue to take various medications prescribed by your doctor on time. Commonly used medications include anticoagulants, cardiac diuretics, anti-arrhythmics, etc. (2) Learn to adjust the dose of anticoagulant medications on your own. Due to individual differences, each patient requires a different dose of anticoagulants. The doctor has initially mapped out the patient’s anticoagulant dose at the time of discharge, and regular laboratory tests should be performed after discharge to further adjust their anticoagulation therapy. (3) Prevent infections, especially respiratory inflammation, periodontitis, skin boils, and urinary tract infections. They should be controlled as soon as they are detected. Intermittent or persistent fever of unknown origin should not be treated indiscriminately with antimicrobials. You should seek medical attention promptly. To avoid delaying treatment. (4) Appropriate activity should be maintained after surgery in order to enhance physical fitness and improve quality of life while recovering from cardiac function. The amount of activity should be measured and gradual, so as not to cause shortness of breath. Do not spend the whole day in bed to rest. (5) Arrange your early recuperation life, keep your spirit happy, relaxed, optimistic and confident. (6) Do not avoid eating, pay attention to increase nutrition, supplement protein and vitamins. It is not advisable to eat too salty food. Patients with poor heart function should limit the amount of water they drink, and should not eat a lot of thin rice and soups, so as not to increase the burden on the heart with too much liquid. (7) A detailed examination (including physical examination, electrocardiogram, chest X-ray, echocardiogram, etc.) should be conducted at the hospital three months after surgery, and the medication should be adjusted according to the examination results, and health guidance for future life and work should be made.
