1.Medication Those with good recovery of heart function after congenital heart disease surgery generally do not need to take cardiac and diuretic drugs. Patients with complex malformations and severe pulmonary hypertension or poor cardiac function should take cardiac, diuretic or vasodilator drugs as prescribed by the doctor after surgery. Before discharge from the hospital, you should ask the name of the drugs taken (such as digoxin, furosemide, potassium citrate); the dose, the time of taking, the possible side effects and the treatment method, do not take the drugs at random to avoid danger. The doctor prescribed drugs should go to the hospital to review after eating, in order to understand whether they need to continue to take, not to decide on their own. 2.Special care Family members should pay attention to correct the incorrect posture of the patient, especially after the left (right) side incision surgery, the patient is often afraid to move the left (right) arm after surgery, afraid of pain, walking with a slanted body, one shoulder is low and the other shoulder is high. Family members should encourage the patient to move the operated side of the arm more often and to walk in a proper posture.
