Strenuous exercise, prolonged bed rest and no anticoagulation are forbidden after adult cardiac occlusion. 1. Contraindication of strenuous exercise: strenuous exercise may easily lead to dislodgement of the blocker, resulting in serious consequences. After the patient’s condition is stabilized, then appropriate activities. If arrhythmia, dyspnea and other symptoms occur, we should consult the doctor at the first time, and if it falls off, we should take cardiac catheterization to take it out, and if it is serious, we should carry out emergency open-heart surgery. 2. Avoid prolonged bed rest: prolonged bed rest increases thrombosis, patients should be encouraged to get out of bed 24 hours after the operation, to prevent venous thrombosis of the lower extremities, the bed activity should be gradually increased, to avoid a sudden increase in the amount of exercise, in order to prevent the puncture site because of the bandage braking, local thrombosis, thrombus dislodgement caused by pulmonary embolism and sudden death. 3. Avoid not carrying out anticoagulation treatment: not carrying out anticoagulation treatment will easily lead to thrombosis around the blocker, and thrombus dislodgement can lead to pulmonary embolism, cerebral embolism and other serious consequences, so it is necessary to give subcutaneous injection of low molecular heparin and oral aspirin to carry out anticoagulation treatment after the operation. If there is any change in breathing difficulty or consciousness, the patient should consult a doctor immediately. After cardiac occlusion surgery, one should pay attention to strengthen the nursing care, take medicines on time according to the doctor’s instructions and avoid the above mentioned contraindicated activities, which can help the recovery of the disease.
