   "How to say?" Director Zheng urged, hurry up.

   Said to drain pus and quickly came up with a well-founded strategy, so as to decide whether to do it or not.

Pan Shihua reconsidered his thoughts, looked at the drainage bag connected to the patient's drainage tube, and said, "I did not use a negative pressure bottle but a drainage bag, which means that the negative pressure suction has no effect, and I am afraid it will have the opposite effect. Distortion problem or unknown problem. Blocking casually with negative pressure suction is irresponsible and high risk.”

   Classmate Pan's idea is the same as hers, but she didn't come up with it after seeing her. This point Xie Wanying knows best, it shows that the classmates are actually quite talented, but they are just a little bit of advice.

   "You said it was probably twisted. They could try to push and rotate the tube to solve the problem. Did the previous doctor not do it or couldn't do it?" Director Zheng continued to question.

  If the drainage tube is discounted in the inside, the drainage tube can be artificially rotated and pushed or even pulled out. This is a common method used by clinical surgeons to deal with drainage tube problems. Like the question raised by Director Zheng, why did the previous surgeon not do it.

   Director Zheng's question is not easy to answer.

   The gang standing at the scene were all caught up in the crux of the problem.

   Pan Shihua was afraid that Director Zheng would turn his head to pursue the responsibility of Xie, and immediately said again: "I know." In any case, he would not let Xie carry this responsibility.

   Director Zheng had to turn around and ask, "Do you really know?"

   Dr. Jiang quietly looked down at Xie Wanying: Won't you say a few words for him?

  Mr. Jiang seemed to know exactly where Pan's ability might be, but seriously underestimated Pan's willpower. Xie Wanying didn't plan to intervene, she had to trust Classmate Pan, who wanted to save her friend's golden heart as much as she did.

"I know." Pan Shihua said, "the length of the drainage tube in the abdominal cavity should be kept as short as possible and the shortest path should be selected. The patient's abscess may be deep, so the tube can only be placed deeper. The omentum separates the tube from other organs, keeping the tube away from the intestines and blood vessels to avoid compression."

   "What you said is all the basic truth, and you didn't explain why you want to do it and the other party doesn't do it."

   "There may be only one reason. According to the CT film taken by the patient before, the previous attending doctor suspected that the tube could not be removed."

   When a group of people on the scene heard the answer, they opened their mouths and looked at Classmate Pan.

   Dr. Jiang's hand on his forehead was like wiping sweat twice: Classmate Pan is not Classmate Xie, if it were Classmate Xie's brain, he would be famous already.

  Yue Wentong, the monitor, seems to need to raise a pimple between his brows sadly, thinking about how he needs to help his classmates.

  Huang Zhilei was relatively calm, standing on the edge, sometimes touching the frame of his glasses, and looking at the subtle expressions of the little sister and her classmates: Well, this expression is a bit subtle, it seems to be hiding some secrets, don't worry.

   "Cough cough." Director Zheng cleared his throat to remind the medical students not to be inconsistent.

   Everyone was surprised by his words. Pan Shihua's heart could only change his mind: everyone didn't trust him and more trusted Xie. He could understand that what he said came from Xie's thinking.

  This morning, Xie said that there may be unpredictable factors in the body of this patient after the surgery, which may lead to the possibility of displacement of the drainage tube or abscess.
