The problem is, a drainage tube is just a tube, not some magical healing item.
To make it work, it requires the doctor's skills to allow it to play the maximum role within its possible range.
What is the effective range of the drainage tube? We can compare the drainage tube to a canal. The water source (pus) above is best surrounded like a lake so that the water (pus) inside does not run around. If the pus flows everywhere, a tube like a canal will not have the attraction to suck all the pus out here, and the effect will inevitably be compromised.
For the pus to be surrounded on all sides like a lake, it means that there are conditions for the formation of pus. Generally, it occurs during the early stage of inflammation in the human body. At this time, the inflammation is local and limited. Because when the human body learns that it is infected with bacteria, it will first organize its 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 greater omentum, etc., to form an encirclement of the bacteria to prevent it from spreading. This is called the common encapsulated abscess. Such an abscess has a distinctive feature, like a lake, with walls on all four sides. Opening a hole in the pus wall and connecting a drainage tube like a canal is a medical procedure commonly performed by doctors, called incision and drainage.
The above explanation proves that the drainage tube cannot be left in place at will. There must be necessary indications for leaving the drainage tube in place. Otherwise, it will be useless and may even do more harm than good. After all, the drainage tube is still a foreign object to the human body. Even if it is disinfected before placement, if it is left in place for a long time, it may still cause infection of the drainage port, bleeding in the drainage tube, or even the drainage tube itself may break in the abdominal cavity.
These are the basic surgical knowledge. Normally, medical students just follow their teachers’ instructions and don’t think about so many basic principles. Practicing manual skills is a matter of practice makes perfect; simply memorizing is useless.
Rethinking the basic theoretical knowledge of medicine means that you have to think independently when encountering difficult and complicated cases, just like clinical teachers. Now Director Zheng asked them what the medical students meant by this: if you were asked to handle the situation yourself as a doctor, how would you think?
Go back to the basics and look through the textbooks to understand the principles. Being a doctor is a profession where you have to keep learning throughout your life. Learning this is just like taking exams in school. You have to constantly review the knowledge you have learned in the past. The basics of medicine are like the mathematical formulas of physics. When combined with clinical practice, you will have new insights and then take clinical exams.
What is the medical basis? The pus neutrophils I just mentioned are physiological content.

You, a student, said that the pus could not flow out because the drainage tube was twisted. Is it because you have no experience in clinical treatment skills that you think of this physiological content?
Pan Shihua thought to himself, that's not the case. He saw Xie looking at the patient's previous CT scan when he was talking in the morning. Later, after his classmate was hospitalized, he took the film and examined it carefully. He felt that this was what Xie was thinking. It turns out that Xie’s idea was to review the textbook knowledge like an old doctor.
Seeing the doubts flashing across Holmes Pan's face, Xie Wanying could only blink. She was a laboratory doctor before her rebirth and had accumulated this kind of clinical learning and review experience long ago. This is also the reason why she can make faster progress in clinical practice than other students of the same age.
