Pan Shihua’s heart was beating a little. He wasn’t a female academic prodigy and knew that there was a gap in strength, but that didn’t stop him from trying hard to catch up. His fair face solemnly nodded to the leader, and said, "The position of the drainage tube might not be too shallow to be inadequate, but possibly too deep, not ruling out it being twisted inside, similar to a blockage."
Director Zheng listened to his answer while trying to recall who he was. The face of this student seed a bit familiar, but he couldn’t rember the na.
"Director, he is a student who just ca to our departnt for a rotation internship, nad Pan Shihua, a classmate of Xie Wanying." Seeing the leader’s gaze cast over, Doctor Jiang reported.
Student Xie has quite a few classmates; it’s hard to rember all of them. If Director Zheng could rember one or two faces among all the dical students in the hospital every year, that would be quite good.
Faced with the teacher not recognizing him, Pan Shihua now appeared composed. He felt that, unwittingly, he had caught the sa affliction Xie seed to have: he didn’t care if people recognized him or not; he just wanted to save people.
This is colloquially known as a single-minded problem.
Acquiring such a problem isn’t easy. In the past, he couldn’t, because he didn’t have the confidence; now he had a little bit.
Knowing who he was now, Director Zheng continued to ask, "Do you know what the drainage tube is for?"
This question seed very basic. The more basic sothing is, the harder it is to answer. If one only answers using the textbook, the leader might disdain you for parroting the text.
"The function of the drainage tube can be roughly divided into two types." Pan Shihua shared the insights he had gained from his clinical learning, "One is for treatnt purposes for the patient. The other is the one generally left post-surgery, whose purpose is for preventive work, such as monitoring for anastomotic leaks, preventing postoperative infection, and tily detection of so postoperative complications."
"Hmm, hmm." Director Zheng listened while responding, then asked, "What is the drainage tube for in this particular patient?"
"My classmate—" Pan Shihua suddenly recalled Xie’s words, that patients should be treated equally, and imdiately corrected himself, "Currently, the drainage tube in this patient is being used for treatnt purposes."
"Is it to drain pus? Can you explain more specifically how the drainage tube can drain pus?" Director Zheng asked.
How can a drainage tube drain pus? The leader’s questions were becoming increasingly peculiar.
First, explain the formation of pus. When inflammation occurs in the body, the body’s cells and invading bacteria engage in combat, and after an intense battle, batches of body cells sacrifice and perish. The remains, along with killed bacteria, mixed with blood vessel exudate and other tissues, form a thick liquid known as pus. Perhaps people can imagine pus as the battlefield scene after a war: rivers of blood flowing.
Pus visible to the naked eye can be white, yellow, or gray-yellow, seen oozing from exposed wounds on the body’s surface, or doctors can artificially create an opening to allow deep-set pus to flow out. The reason doctors must allow pus to flow out of the body is that, in addition to denatured and necrotic neutrophils, called pus cells, it contains bacteria. It serves as a source of infection in the body, which can lead to recurrent infections, ultimately feared to spread throughout the body, turning into sepsis.
Understanding the reason the drainage tube must allow pus to flow out of the body, the drain left by the doctor becos critically important like a magical artifact. If it remains open, it can discharge the source of infection, allowing the wound inside the patient to heal.
