Precautions after surgery: 1. Maintain a good posture after surgery. After surgery, patients with medium or minor surgeries will be sent back to the original ward immediately, while patients with major or critical surgeries will be sent to the ward. In the postoperative ward, patients under general anesthesia are not yet awake at this time and should lie flat without pillows, with their heads tilted to one side to prevent saliva or vomitus from being inhaled into the respiratory tract and causing respiratory infections. 2. Assist medical staff to observe body temperature, pulse, respiration and blood pressure. If you feel unwell, have a fever, or have a rapid heartbeat, you should report it to your doctor and nurse immediately. 3. Strengthen dietary coordination and nutrition after surgery to facilitate physical recovery. 4. Assist medical staff in strict postoperative wound management. 5. Get out of bed early after surgery. 6. Know the best time to remove sutures. 7. Some patients are not used to urinating in bed after surgery or have urinary reflex disorders and cannot urinate. At this time, training is required. To eliminate scars, it is recommended that you use vitamin E, which can penetrate into the skin to exert its emollient effect and eliminate scars. Suggestions: At the same time, vitamin E can also maintain skin elasticity. But you may not be familiar with the scar-removing effect of vitamin E. Prick the vitamin E capsule with a needle, apply the liquid on the scar and gently massage it for 5-10 minutes, twice a day. If you persist, you will have better results.
