Why Do You Put A Drainage Tube in The Surgery

In clinical work, especially in surgical procedures, drainage tubes are often placed on patients. There are many drainage methods for wounds, including skin drainage, cigarette drainage, tubular drainage and even double cannula drainage. Different drainage methods have different purposes and slightly different drainage positions. The drainage tube is usually placed in the abdominal cavity or the chest cavity, because the corresponding thickness of the tube is needed for continuous drainage. The main purpose of the drainage is to observe the situation inside the wound, such as whether there is abnormal bleeding or the gastrointestinal anastomotic orifice is not well developed and anastomotic fistula occurs, and then pulp the dirty things in the abdominal cavity. For example, purulent secretions are discharged outside the body through drainage tubes to accelerate wound healing. Therefore, drainage tubes play an important role in surgical observation and treatment, sometimes very important.
