   Now the surgery is at a critical stage.

  Several surgeons tried their best to remove the artificial mitral valve from the patient's heart that had stopped beating. It was really sticky and thrombus.

  Doctors should take it carefully to avoid residual thrombus. Otherwise, when the heart recovers, the thrombus will be pumped with the blood flow of the heart, and a pulmonary embolism or cerebral thrombosis will be properly handled.

   Du Mengen and Zhang Shuping stood in the corner until their ankles were sore, and it was not easy to be a medical student. If I don’t work and observe and study here, the more I look at it, the more anxious I get, and I can’t wait for the surgery to end earlier than anyone else. In fact, after watching an operation, there are very few so-called technical pictures. The most common scene seen by medical students is that doctors are forced to slowly grind foreign workers as they are now. A little bit of carelessness will bring a lot of postoperative problems to the patient.

  Dr. Du Yeqing is a conservative and will make every detail of the operation more careful within the limited time.

   Touched the back of his sore neck, Dumont was no longer interested in being a cardiac surgeon. The extra-cardiac surgery takes too long and is torturous. In contrast, routine operations in gynecology are shorter, and obstetrics are shorter.

   Zhang Shuping, who was standing beside him, had a stiff face, obviously trying to stand up.

   "It's not very good here." Only the surgeon on the operating table muttered.

   "What's not so good?" Du Mengen asked Zhang, who was more skilled.

  Zhang Shuping is just a trainee. He doesn't usually practice in his uncle's hospital. This kind of operation is rare. After thinking about it for a long time, he answered: "Is it true, the valve port is not good-"

  Valve orifice? Zhang should be referring not only to the opening and closing of the valve, but also to the location of the valve.

  While removing the damaged artificial valve, the surgeon needs to consider which valve to replace next. It is the only way to find out and judge the surrounding environment of the valve site to select the appropriate valve type.

   In short, artificial valves are roughly divided into two types: mechanical valves and biological valves. This patient used a mechanical valve before, but there was a problem. According to inertial thinking, it must be another type of things that don't work. Maybe you can replace it with a biological valve to avoid the same problem.

   However, the solution to medical problems has never been such a simple mental map to refer to.

  First of all, why did this patient choose a mechanical valve for the first operation?

   The doctor who performed the operation for the first time should know that the patient is a young woman and the patient herself needs to be pregnant. Due to the long-term use of anticoagulants such as warfarin after surgery, mechanical valves are prone to thrombosis, which will affect women's pregnancy and childbirth. The various disadvantages mean that a mechanical valve does not seem to be the first choice for this young woman in need.

   Like this patient, it was because of the special hypercoagulable state during pregnancy that the mechanical valve was clogged with thrombus and had to be re-operated urgently.

   In this way, the doctor who performed the operation on the patient for the first time did not think carefully about the patient?

   On the contrary, preoperative cardiac surgeons routinely introduce various valves to patients. It is equivalent to saying that as long as the patient's physical condition allows, the patient can decide which valve he wants to install. Let the patient make a choice first, because the patient has his own economic interests in the cost of treatment. How much a patient is willing to spend for their own treatment is something non-doctors can decide for the patient.
