Pan Shihua's heart beat a little. He was not a female academic master. He knew that there was a gap in strength, but this did not prevent him from trying hard to catch up. His fair face pointed to the leader seriously and said, "The position of the drainage tube is not too shallow and not enough. It may be too deep. It is not ruled out that it is twisted inside, like a blockage."

Director Zheng listened to his answer and recalled who he was: the classmate's face had a little impression, but he couldn't name it.

"Director, he is a student who just came to our rotary internship. His name is Pan Shihua and is a classmate of Xie Wanying." Seeing the leader's eyes coming, Dr. Jiang reported.

There are many classmates in Xie, and I can’t remember them all. It’s great that leaders like Director Zheng can remember one or two faces among all the medical students in the hospital every year.

Pan Shihua is now calm about the teacher's condition. He felt that he had been infected with that kind of problem by classmate Xie unknowingly: whether others know him or not, he just wants to save people.

This is commonly known as a stubborn problem.

It is not easy to suffer from such a problem. He didn't have the confidence to suffer from this before, but now he is a little bit more.

Knowing who he is, Director Zheng continued to ask: "Do you know what drainage tube does?"

This question seems to be very basic. The more basic the thing is, the less easy it is to answer. If you just answer it with the answers in the textbook, the leader will probably dislike you for following your script.

"The function of drainage tube can be roughly divided into two types." Pan Shihua said his experience after studying clinically, "One is for treatment for patients. The other is usually reserved after surgery, with the purpose of allowing it to do some preventive work, such as monitoring whether there is anastomotic fistula, preventing postoperative infection, and timely discovering some postoperative complications."

"Yeah." Director Zheng responded while listening and asked again, "What is the drainage tube for this patient at present?"

"My classmate--" Pan Shihua suddenly remembered the words of classmate Xie, and treated the patients equally and immediately changed his words, "At present, this patient has a drainage tube for treatment."

"Is it true to discharge pus? Let me talk about it in detail, how can the drainage tube discharge pus?" Director Zheng asked.

How can drainage tubes discharge pus? The leader’s problem is becoming more and more strange.

Pus discharge first indicates the production of pus. Inflammation occurs in the human body, and cells in the body fight against bacteria that invade the human body. After the fierce struggle, human cells are sacrificed in batches. The remains left behind and the killed bacteria are mixed with blood vessels to seep out of liquid and other tissues. The thick liquid formed together is called pus. Perhaps, people can imagine pus as a battlefield scene left after the war: blood flows into a river.

The pus seen in the naked eye can be white yellow, gray-yellow, etc., which can overflow when the wounds exposed in the human body, or a doctor artificially opens a hole in the human body to allow the pus deep inside the body to flow out. The reason why the doctor must let the pus flow out of the body is that in addition to the degenerative and necrotic neutrophils called pus cells, the pus contains bacteria. It is a source of infection in the body, which will cause continuous recurrence of infection in the body. The most fear of the infection eventually spreading to the whole body and becoming sepsis.
