Nursing after knee replacement includes many aspects:
1. Vital sign monitoring: Knee joint replacement is generally aimed at the elderly, often complicated by some basic diseases. Routine oxygen inhalation should be performed after operation, and the changes of vital signs of patients should be monitored by ECG monitoring, and the patients' conscious state, peripheral blood circulation, skin temperature and toe sensory activity should be observed. If there is any abnormality, you should inform the doctor.
2. Body position and diet: Generally, patients take supine position, and the affected limbs are raised. After the swelling is eliminated, he can gradually lie in a semi-recumbent position or sit. Encourage patients to eat a high-protein and vitamin diet.
3. Nursing care of drainage tube: Pay attention to incision exudation and drainage. If the incision exudation increases, the doctor should be informed to change the dressing, and if the drainage volume is large, the doctor should be informed in time. Generally, when the drainage volume is less than 50ml, the drainage tube can be removed 24 ~ 48 hours after operation.
4. Pain care: generally use an analgesic pump to relieve pain after operation. Those who don't use analgesic pump can use analgesic drugs orally or intravenously, and at the same time, do a good job of psychological nursing to divert patients' attention and reduce their psychological burden.
5. Functional exercise: encourage patients to take a deep breath, cough and expectoration, strengthen turning over and patting the back, and prevent pneumonia and bedsore. Instruct patients to perform quadriceps contraction, ankle pump exercise and knee flexion and extension exercise to prevent muscle atrophy and joint stiffness.
