Many patients still have one or even several drainage tubes in their bodies when they are discharged from the hospital, and these tubes need to be taken care of by their families to function well, so I will make a brief introduction here. There are several types of tubes that can be left in place, and I will classify them as follows: drainage of pancreatic fistula and pseudocysts: these tubes generally need to be left in place for at least six months, and the daily drainage flow will vary from tens to hundreds of milliliters. This tube does not need to be flushed, but it must be fixed in place, if it comes out then it can only be punctured again, the sinus tract closes quickly, and the risk of puncturing again is great. All that is needed is local disinfection and timely replacement of the fixation tape every day. If the drainage flow suddenly becomes smaller for a few days, it is likely to suggest dislocation and needs to be confirmed by medical examination. General Surgery Department of Nanjing Military Hospital Ke Lu drainage abscess tube, this tube often needs a small amount of flushing every day, and the drainage flow is also very small. There may be a little yellow pus for a long time, this is not a cause for concern, due to the rejection of the tube, more or less pus will be drained out, and we will remove it as soon as possible after reviewing the CT. Again, it is very important to fix and keep it dry. If the granulation on the side of the tube grows very much or even a small amount of bleeding, please consult us promptly; tube for drainage of enterocutaneous fistula It is very important to keep the drainage of this tube open, and openness also requires daily flushing to avoid the erosion of intestinal fluid or a small amount of stool. We will arrange for these tubes to be taken home. The amount of fistula is usually very small, so it is not necessary to worry too much about keeping them flushed and drained. Gallbladder drainage tube: please follow the doctor’s instructions for the use of this drainage tube, usually we will first hang high, close to see if there are no symptoms, if there are no symptoms we will arrange a cholecystogram to clarify the situation of the gallbladder duct, and only then can be removed. Gallbladder drains are not easy to remove, so please contact me on the platform if you have any questions. I hope it will be helpful to you.
