Patients using abdominal drains to drain ascites, when can be removed, this depends on the amount, color, nature and other factors of the daily drainage of ascites from the drainage tube for objective analysis. First, if the amount of ascites drained from the drainage tube for 3 consecutive days is less than 20 ml and the color is clear, it indicates that the inflammation in the abdominal cavity gradually subsides and the fluid is significantly reduced, so the removal of the abdominal drainage tube can be performed. Second, if the patient’s abdominal pain and abdominal distension symptoms are obviously relieved, without the use of laxative drugs can be self-exhaustion, defecation suggests that the gastrointestinal function gradually restored, the condition is improved, also feasible to remove the abdominal drainage tube. Third, through the abdominal ultrasound or CT examination, no abdominal cavity with a large amount of fluid, then also can be removed from the abdominal drainage tube. If the drainage tube is placed for a long time, it may cause local retrograde infection, which is not conducive to the patient’s care and activities and does not enable the condition to recover faster.
