Returning to ’90s, She Became Famous in Major Surgical Fields

   Director Zheng listened to his answer and recalled who he was at the same time: the face of this classmate is a bit impressive, but he can\'t name it.

   "Director, he is a student who has just come to our Kelun Department for an internship. His name is Pan Shihua, and he is Xie Wanying\'s classmate." Seeing the leader\'s gaze, Dr. Jiang reported.

  Xie classmates have a lot of classmates, I can\'t remember them all. It is good that a leader like Director Zheng can remember one or two faces among all the medical students in the hospital every year.

   Pan Shihua is calm now that the teacher can\'t recognize him. He felt that he had unknowingly been infected by Xie classmates: he just wanted to save people regardless of whether they knew him or not.

   This is commonly known as a sinew.

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

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

   This question seems very basic. The more basic things are, the harder it is to answer. If you just answer with the answers in the textbook, it is estimated that the leaders will dislike you according to the script.

"The role of the drainage tube can be roughly divided into two types." Pan Shihua said that he summarized his experience after clinical study, "one is for the treatment of patients. The other is for general postoperative retention, the purpose It is to let it do some preventive work, such as monitoring for anastomotic leakage, preventing postoperative infection, and detecting some postoperative complications in time."

   "Hmm." Director Zheng listened and responded, then asked, "What is the current drain tube for this patient?"

   "My classmate—" Pan Shihua suddenly remembered what classmate Xie said, treating patients equally, and immediately changed his words, "Currently, this patient\'s indwelling drainage tube is for treatment."

   "Is it draining pus? Can you be more specific about how the drainage tube can drain pus?" Director Zheng asked.

   How can a drainage tube drain pus? The question of leadership is getting more and more bizarre.

   Drainage first describes the production of pus. Inflammation occurs in the human body, and the cells in the body fight against the bacteria that invade the human body. After the fierce struggle, the human cells are sacrificed in batches, and the remains and killed bacteria are mixed with blood vessels and other tissues to form a thick liquid. It is called pus. Perhaps, one can imagine the pus as the battlefield picture left after the war: the blood flows into the river.

   The pus seen with the naked eye can be white, yellow, grayish-yellow, etc. It can be seen in the overflow of wounds exposed on the human body, or the doctor artificially opens the human body to allow the pus deep in the body to flow out. The reason why doctors must let the pus flow out of the body is that in addition to the degenerated and necrotic neutrophils called pus cells, the pus contains bacteria, which are a source of infection in the body, which will cause the body to keep recurring infections. Eventually the infection spreads throughout the body and becomes sepsis.

   I figured out the reason why the drainage tube allows the pus to flow out of the body. If the drainage tube left by the doctor becomes a magical object, it is very important. If it is unobstructed, the source of infection can be discharged from the body and the wound in the patient\'s body can be healed.
