The problem is that the drainage tube is just an ordinary tube, not a magical item with therapeutic effects.

To make it work, you need to see a doctor's technique to make it work as much as it can.

Where is the scope of the drainage tube? We can use the drainage tube as a canal. The water source (pus) on the top is preferably wrapped around it like a lake so that the water (pus) inside is not messy. Run. If the pus flows everywhere, a pipe like a canal is just that attractive. It will suck all the running pus here and flow out. The effect will inevitably be reduced.

To make the pus surrounded by all sides like a lake, it means that the pus has conditions to form. Generally, when the human body is in early inflammation, the inflammation is local and has limitations, because when the human body learns that the human body is bacterial, it is known that the human body is ill and bacteria. , first organize forces to surround the bacteria that have just begun to invade the human body, including mobilizing white blood cells. If it occurs in the abdominal cavity, it will mobilize the nearby omentum, etc., forming a circle of the bacteria and preventing it from spreading. It is called our common enclosed abscess. . Such abscess has a distinctive feature like a lake, with walls on all sides. Opening a hole in the pus wall and connecting it with a drainage tube like a canal is a medical operation commonly performed by doctors called incision and discharge of pus.

The above instructions confirm that the drainage tube cannot be left at will. If it is left, it requires necessary indications. Otherwise, it will be useless and will become harmful and unprofitable. After all, the drainage tube is also an external object to the human body, even if it has been disinfected. If left, but if left for a long time, it will also cause infection of the drainage port, bleeding from the drainage tube, and even if the drainage tube itself is broken into the abdominal cavity.

These are basic surgical knowledge. Usually, medical students follow the teacher and don’t think of so many basic principles. Exercising your hand is a practice that makes you perfect, and memorizing is useless.

Thinking about basic medical theory again means that you have to think about it alone when encountering difficult and complicated diseases like clinical teachers. Now Director Zheng asks them about this meaning of medical students. If you are asked to deal with it yourself, yours will be How to think.

Go back to the basics, go back and look through the textbook and think about the principles. Doctors are an industry that can learn until they are old. This learning is like taking exams in school. You have to constantly take out the knowledge you have learned in the past and review it. The basics of medicine are like physics. Learn the final mathematical formulas and combine them with clinical practice to find a newer experience, and then do clinical test questions.

What is the basis of medicine? The pus neutrophils I just mentioned are physiological content.

Your student said that the drainage tube was twisted and caused the pus to fail to come out. Is it because you did not accumulate experience in clinical processing skills because you thought of this physiological content?

Pan Shihua thought to himself, he was not. He was watching the patient's previous ct picture when he was talking in the morning. Later, after the classmate was hospitalized, he took the video and checked it carefully. He felt that classmate Xie was thinking. This is probably the case. It turns out that Student Xie’s idea is to re-review the textbook knowledge like an old doctor.

Seeing the doubts about her flashed across her face, Xie Wanying could only blink. She was a laboratory doctor before she was reborn and had accumulated this kind of clinical study and review experience. This is also why she was able to do clinical practice. The reason for the rapid progress of other students during the same period.
