Closely observe the change of condition. Patients with breast cancer should be operated under continuous epidural anesthesia and intravenous combination anesthesia, and should be placed in a lying position after the operation and closely monitored for blood pressure, pulse and respiration. After breast cancer patients are awake and their vital signs are stable, they should be placed in semi-recumbent position to facilitate breathing and drainage and to avoid or reduce edema of the operated limb. Observe whether the wound dressing is dry or not. In the early stage, use negative pressure suction or chest bandage or sandbag for pressure to help the skin piece to attach and avoid accumulation of blood and fluid under the skin. Pay attention to whether the negative pressure drainage is unobstructed and the blood flow of the operated limb. Prevent edema and dysfunction of the operated limb. Avoid performing venipuncture on the operated limb and elevate it appropriately. Three days after surgery, start to help the patient to move the upper limb, starting from the elbow and gradually extending to the shoulder. The exercise methods are eating by themselves, combing hair, washing face and finger climbing wall activities to promote blood circulation of the limb. The world is beautiful because of love I believe that every patient will understand after reading this, breast cancer disease is more harmful to patients, only timely treatment, patients will be away from the disease.
