Craniotomy care mainly includes the following aspects: 1. Monitoring of the patient’s general vital signs, including respiration, blood pressure, circulation, and pulse rate. The head of the bed needs to be routinely elevated by 30 degrees, which is conducive to reducing intracranial pressure.2. Airway care, airway care is one of the most important aspects of patient care, because airway care is likely to affect the patient’s respiratory function. If the airway is obstructed, it is likely to cause asphyxia and even death of the patient. Therefore, the patient’s oxygen saturation, respiratory function and blood gas need to be monitored.3. Drainage tube care, for patients after craniotomy, various drainage tubes are usually left in place, if abnormal drainage fluid and volume are found, the doctor needs to be notified immediately and the corresponding treatment should be taken.4. Urethral care, because craniotomy patients are often left with catheters, the volume of urine needs to be monitored, and the color and properties of urine need to be If abnormalities are found, the doctor should be notified. 5. Lower limb deep vein thrombosis care, after craniotomy patients are often bedridden, which can easily lead to the occurrence of lower limb deep vein thrombosis, prevention requires wearing elastic stockings, elevating the affected limbs, massaging the lower limbs and other treatments.
