Because endometrial cancer surgery usually requires lymph node dissection, there will be some exudate in the residual lymph after surgery, and a drainage tube will be routinely left in the patient’s abdomen to remove the exudate in time. So many patients may ask how long should this tube be left in place? What is the normal amount of drainage? 1. At the beginning, patients generally discharge about 200~300ml of fluid, and gradually decrease over time; 2. During hospitalization, medical staff will monitor the amount of drainage fluid, and when the daily volume of fluid discharge is about 50~60ml, the tube can be withdrawn; 3. When individual patients have a large volume of fluid discharge, reaching 800~1000ml, the doctor will recommend a CT examination of the urinary system to rule out whether the bladder, ureter (also known medically as bladder fistula and ureteral fistula) is leaking to the point that urine has entered the pelvis. If it is clear after the examination that the urinary system is normal, then there is no need to be nervous about the large amount of drainage; 4. Some patients may not have been discharged from the hospital because of the large amount of drainage, so they must pay attention to keeping the drainage tube clean after they go home to avoid infection. 1. Wrap it with clean gauze, change the drainage bag once in 1~2 days, keep the drainage tube open, and do not pull the drainage tube. 2. The color of the fluid, smell, impurities, etc. The normal drainage fluid is pale yellow translucent clarified, if the liquid appears flocculent like rice soup white things to be alert, in addition to some exudate secretions appear reddish or have an odor, should be promptly returned to the hospital. 3, observe the skin around the drainage tube is not red, swollen, broken, fluid leakage, etc., when the discharge of medical staff will teach patients and families how to clean the skin around the drainage tube; 4, daily record Drainage volume, return to the hospital to remove the tube when the daily drainage volume is around 50~60ml.
