The abdominal drainage tubes are mostly made of rubber. Rubber itself has the characteristic of becoming easily fatigued and breaking. Many doctors later switched to using silicone tubes because of this, as there have been many similar incidents with rubber tubes. However, silicone tubes are not as cheap as rubber tubes, nor are they as soft and elastic. Veteran doctors who are accustomed to rubber tubes are not too fond of silicone tubes, and besides, softer and more elastic tubes feel better in hand. All in all, which tube to use depends on the doctor’s personal habit. But no matter which tube is being removed, it doesn’t make a difference to the doctor; it’s definitely a technical task. Medical students who have undergone surgical internships have removed tubes before; teachers generally let students practice this task. Having rotated through gynecology, Pan Shihua has removed drainage tubes several times and has a feel for this, which is why he dares to use some force. Surgical students need to be bold yet careful. At the same time, he exchanged glances with Student Xie, whose eyes approved of his method of pulling. Rubber tubes, much like rubber bands, have another characteristic: excellent elasticity. If the front end gets stuck, it seems like a lot of force is being used when pulling from the tail end as if to pull out the entire tube, but actually, it’s not the case. Even without much force, doctors often find that the tube snaps back with a swoosh, and only a small segment at the top can be gently pulled out. Director Zheng, experienced as he is, could discern from the slight noises of the rubber tube being manipulated in the doctor’s hands. The action might seem vigorous, but the actual force is light, and not much length should have been pulled out. Doctor Jiang calmed his emotions, crouched down to observe the drainage tube in the student’s hands, and reported to the supervisor, "About half a finger’s length has been pulled out." "Very short," Director Zheng estimated. This drainage tube was placed deeply in the patient, and half a finger is only one centimeter. The length pulled out is nothing to fear; the most important thing is whether moving the tube proves effective. If it’s ineffective, it would be as if nothing was done, and surgery would still be necessary, becoming troublesome. "Something is coming out," Doctor Jiang said, a glimmer of excitement flashing in his eyes as he watched the drainage tube, symbolizing that hope could ignite. "Really?" Receiving this hopeful information, Li Guoxin immediately moved past the foot of the bed, pushed Doctor Jiang aside, and bent down himself to personally check the situation. The brown rubber drainage tube is darker in color and semi-transparent; if something is coming out inside, the doctor needs to carefully discern it, squeezing, rubbing, and flicking the rubber tube to let the substance slide into the transparent tube connected to the drainage bag for closer inspection. Li Guoxin’s right hand eagerly reached out, placed below where the student held the drainage tube, and began flicking the tube skillfully, waiting for the substance to fall into the transparent tube and the transparent drainage bag.

The situation suggested that the patient’s pus cell count had increased, causing a rise in temperature, and it seemed likely that diffuse peritonitis had not yet formed since the pus could continue to discharge from the tube without flowing out like an open faucet, indicating that residual pus hadn’t been fully discharged yet. However, the situation is quite critical; the pus must not burst. The absence of flowing blood also implies no significant hemorrhaging. The low red blood cell count might be due to the patient’s poor nutritional support throughout the body. "As long as the pus inside can be drained out next, there’s hope for reducing the fever, and immediate surgery might not be needed," Li Guoxin said.
