Drainage tube is usually about 2-5 days after operation. When the patient is in good condition and there is no drainage fluid, it can be taken out.

The time to pull out the drainage tube should be determined according to the specific situation of the patient and the purpose of the operation. Usually, after brain, chest or abdominal surgery, such as intracranial hematoma removal, appendectomy or cholecystectomy, a drainage tube is used to remove irrigation fluid and exudate. In general, 2-5 days after operation, the patient is basically in good condition, and there is no obvious drainage fluid. The doctor can pull out the drainage tube at an appropriate time. Under special circumstances, the patient may need to carry the drainage tube for a longer time.
