The issue is that a drainage tube is just an ordinary tube, not some magical item with therapeutic effects. To make it work, it depends on the doctor’s skill to ensure it functions maximally within its effective range. What is the effective range for a drainage tube? We can liken the drainage tube to a canal, with the source of water (pus) ideally encased like a lake, tightly surrounded on all sides, so the water (pus) inside doesn’t run everywhere. If the pus flows everywhere, a tube-like canal can’t exert enough attraction to draw all the wandering pus here to drain out, making the effect inevitably compromised. Latest content publıshed on 𝗻𝗼𝘷𝗲𝗹•𝓯𝓲𝓻𝓮•𝕟𝕖𝕥 To make the pus encased like a lake, it suggests conditions for pus formation. It’s generally during early inflammation in the body when inflammation is localized. When bacteria initially invade the body, it organizes white blood cells and, if in the abdominal cavity, mobilizes the surrounding omentum to form a barrier against the bacteria, preventing its spread, creating what we commonly know as encapsulated abscess. Such abscess, like a lake, has a notable feature—walls on all sides. Opening a hole in the abscess wall and connecting it to a canal-like drainage tube is a common medical procedure known as incision and drainage. The above explanation confirms that drainage tubes cannot be placed arbitrarily. Placement requires necessary indications; otherwise, it is not only useless but harmful, because despite sterilization, drainage tubes are foreign objects to the body and can cause infection at the drainage site, bleeding from the drainage tube, or even the tube breaking inside the abdominal cavity if left for too long. These are basic surgical knowledge. Typically, medical students follow their instructors’ operations without thinking much about these basic principles. Skill enhancement comes from frequent practice; mere rote memorization is useless. Rethinking basic medical theoretical knowledge transforms you into a self-thinking clinician faced with complex cases. This is what Director Zheng implies by questioning the medical students—if you were handling it as a doctor yourself, how should your thinking process be? Returning to basics, revisiting textbooks to think about principles. Medicine is a lifelong learning profession. This learning is akin to classroom lessons and exams, continuously revisiting previously acquired knowledge, akin to physics laws and mathematical formulas, which, when combined with clinical practice, yield new insights, aiding in solving clinical issues. What is medical basics? The previously mentioned pus and neutrophils are physiological content. You, the student, said the twisted drainage tube caused improper pus drainage; is it because you lack accumulated experience in clinical handling skills and instead thought of this physiological content? As Pan Shihua contemplated, he realized it wasn’t; he recalled watching Student Xie looking at the patient’s previous CT images and later, after the hospitalization, he examined that image more thoroughly, sensing that Student Xie’s thoughts were likely along those lines. As it turns out, Student Xie’s approach was akin to an experienced doctor revisiting textbook knowledge. Seeing a flash of doubt about her on Sherlock Holmes Student Pan’s face, Xie Wanying could only blink. Before her reincarnation, she was a laboratory doctor, already having accumulated such clinical learning review experience. This is also why she progresses faster clinically compared to her peers.
