Blood and water in the drainage tube after total uterine excision usually manifests as a clarified yellowish liquid before the tube can be considered to be removed. However, the indications for drainage tube removal are not only to observe the color of the drainage fluid, but also to observe the drainage flow rate of the tube and the patient’s physical condition, etc. 1. Drainage tube color: The purpose of placing the drainage tube is mainly to prevent the anastomosis from healing poorly and to drain the residual tissue fluid and blood in the abdominal cavity. When the drainage tube is clarified yellowish liquid, this liquid is the normal exudate of the human abdominal cavity, which indicates that the wound has healed, and can be considered for removal in combination with other indications. 2. Drainage flow of the drainage tube: The drainage flow of the drainage tube placed in different parts of the body is different for the indication of extubation. When the patient’s daily drain flow is small, not more than ten milliliters, then consider pulling out the tube. 3. Patient’s physical condition: Observe whether the patient has any signs of fever and infection, and whether there is any other discomfort, and consider pulling out the tube if the patient’s physical condition is good. It is recommended to go to the hospital to remove the drainage tube under the guidance of the doctor, after the doctor’s assessment, and follow the doctor’s instructions, do not remove the tube on your own.
