   A stool was placed at the door of the ward. After eating, Doctor Yu sat on it and folded his hands on his chest, his head was like a chicken pecking at rice, and his forehead was kowtowed on his crossed arms.

   After a busy day, the young resident doctor is already exhausted, so he doesn\'t need to doze off while working.

  There is another person in the ward anyway.

   Contrary to others, sleep first to replenish energy, Geng Yongzhe guards the beating numbers and graphs on the instrument, his eyes are bright, and he is not tired.

   Hearing footsteps behind, Geng Yongzhe turned to see her and asked, "Why are you back? I said, I\'ll let you know if there is anything."

   "I\'ve eaten too much, check the patient\'s condition before going back to sleep." Xie Wanying said.

   Indeed, eating too much makes it hard to sleep. Geng Yongzhe walked side by side with her and discussed: "The patient\'s vital signs are relatively stable now."

   Hearing this, Xie Wanying asked, "How is the patient\'s blood coagulation?"

   Blood coagulation?

  Some of the issues involved in surgery may be different from what the layman thinks. One of them is probably not something that the public can think of. Doctors are not only afraid of heavy bleeding during and after surgery, but also of hypercoagulable thrombosis during and after surgery. Because the death of patients is sometimes not due to excessive blood loss and shock, but for example, DIC, disseminated intravascular coagulation, or a thrombus suddenly gets stuck in important organs and causes death.

   During the preoperative team discussion of this patient, the doctors generally believed that the patient was in a hypercoagulable state, which caused the prosthetic valve thrombosis. Therefore, a large amount of heparinized anticoagulant was used during the operation to try to counteract the balance of anticoagulation and hypercoagulation. How long does the efficacy of these anticoagulants last after surgery? Whether additional anticoagulation is required. All points to consider.

Geng Yongzhe has never been in heart surgery, and he has never seen open-heart surgery. He is not familiar with this type of surgery. Hearing the problem she pointed out, he fell into thought, and said: "I remember it was mentioned in books that cardiopulmonary bypass in heart surgery can make The fibrinolytic system in the human blood becomes hyperactive, causing postoperative bleeding and thromboembolism."

  Student Geng is also an excellent medical student. He can memorize as much as he can when he studies **** weekdays. He remembers a lot of medical knowledge and can quickly associate relevant knowledge points.

   "Mmmm." Xie Wanying nodded and said, "In general, antifibrinolytics will be given on the same day after heart surgery."

   What Geng Yongzhe didn\'t quite understand was: "Yingying, you said that taking antifibrinolytics on the day after cardiac surgery is a routine strategy after cardiac surgery?" This knowledge point seems to have not been mentioned in the book.

Xie Wanying had some speculations and thoughts about it, saying, "Is it a routine treatment plan for an entire department? I haven\'t communicated with the teacher outside the heart, so I don\'t know. I just saw that they are useful in the department. "

   Geng Yongzhe, who had never observed these scenes in the ward, was amazed at how she managed to find problems everywhere. Medical students generally arrive at the ward to study, and most of them are guided by what the teacher says. It is difficult for medical students to think independently and lead to problems, because without clinical experience, they do not know where to focus.

   Can have a different way of thinking from other medical students, of course, because she Xie Wanying is reborn. As long as it involves things such as laboratory tests of blood indicators, this is her old job before her rebirth, and it is difficult for her not to pay attention.
