The problem is, the drain is just a tube, not some magical healing item.
To make it work, you need to see a doctor's technique, and let it play the most effective role within the range that can be used. Where does the drainage tube work? We can compare the drainage tube to a canal. The water source (pus) above it is better to be tightly wrapped around like a lake so that the water (pus) inside does not run around. like
It's pus flowing around, and it's just a pipe like a canal. How can it have such an attractive force to suck all the pus running around here and let it flow out, the effect must be compromised. Let the pus be surrounded on all sides like a lake, which means that there are conditions for the formation of pus, usually during the early inflammation of the human body. , will first organize forces to surround the bacteria that have just invaded the human body, including the mobilization of white blood cells.
See encapsulated abscess. Such an abscess has a distinctive feature, like a lake, with walls on all sides. Opening a hole in the pus wall and connecting a drainage tube like a canal is a medical operation often performed by doctors called incision and drainage of pus. The above description proves that the drainage tube cannot be left at will. If you want to keep it, you need to have the necessary indications, otherwise it is useless to keep it in place, and it will become harmful instead of beneficial. After all, the drainage tube is a foreign object to the human body.
I am afraid that it will be placed after disinfection, but if it is left for a long time, it will also cause infection of the drainage port, bleeding of the drainage tube, or even the drainage tube itself may break in the abdominal cavity.
These are basic surgical knowledge. Usually medical students follow the teacher's operation and don't think about so many basic principles. Exercising manual work is more practice makes perfect, and mere endorsement is useless. To rethink basic medical theoretical knowledge is to become like a clinical teacher who has to think alone when encountering intractable diseases. Now Director Zheng asks them what it means to be a medical student. If you, as a doctor, handle it yourself
How about your way of thinking. Go back to the basics, go back and look through the textbooks to think about the principles. Doctors are an industry that learns from time to time. This learning is like taking an exam in a school classroom. You must constantly review the knowledge you have learned in the past.
The foundation is like the deterministic mathematical formula of physics, combined with the clinical experience, you will find a newer experience, and then do the clinical examination questions.
What is the medical basis? The pus neutrophils just mentioned are physiological content.
Your student said that the pus cannot come out due to the distortion of the drainage tube. Is it because you have no experience in clinical treatment skills because you think of this physiological content? Pan Shihua thought to himself, I am not, I was watching classmate Xie in the morning when he was talking, he was looking at the patient's previous CT picture, and later after the classmate was hospitalized, he got the film and checked it carefully.
This is what the students thought. It turned out that Xie's idea was to revisit the textbook knowledge like an old doctor. Seeing Sherlock Holmes Pan's face flashing doubts about her, Xie Wanying could only blink. She was a laboratory doctor before her rebirth, and she had already accumulated this kind of experience in clinical study and review. This is also the reason why she can progress faster clinically than other contemporaries.
