Then he turned his head and looked at the operating table.
The operation is now at a critical stage.
Several surgeons took great pains to remove the artificial mitral valve that had been installed in the patient's stopped heart, but it was sticky and full of blood clots.
Doctors have to be very careful when removing blood clots to avoid residual blood clots. Otherwise, when the heart recovers, the blood clots will follow the heart's blood flow and cause pulmonary embolism or cerebral thrombosis.
Du Meng'en and Zhang Shuping stood in the corner until their ankles were sore. Being a medical student is not easy. They are not working here to observe and learn. The more they watch, the more anxious they are. They want the operation to end sooner than anyone else. In fact, after watching an operation, there are very few so-called technical scenes. The most common scene seen by medical students is nothing more than doctors being forced to work slowly like now. They have to slow down. A little carelessness will cause many problems for patients after the operation.
Dr. Du Yeqing is a conservative person and will make every detail of the operation more careful within the limited time.
Touching his sore neck, Du Mengen lost interest in being a cardiac surgeon. Cardiac surgery takes too long and is torturous. In comparison, routine gynecological surgery is relatively short, and obstetric surgery is even shorter.
Zhang Shuping, who was standing next to him, had a stiff face and was obviously trying hard to stay strong.
"It's not working here." The surgeon on the operating table muttered.
...
...
"What's not right?" Du Meng'en asked Zhang, a student who was more knowledgeable.
Zhang Shuping was only an intern. He didn't usually intern at his uncle's hospital, so he didn't see many surgeries like this. After thinking for a long time, he answered, "Is that right? The valve orifice is not good—"
Valve orifice? What Zhang is referring to is not only the opening and closing of the valve, but also the location of the valve.
When the surgeon removes a damaged artificial valve, he or she also needs to consider what valve to use to replace it. It is imperative to understand the surrounding environment of the valve and choose the appropriate valve type.
In simple terms, artificial valves are roughly divided into two types: mechanical valves and biological valves. Previously, this patient had a mechanical valve but it had problems. According to inertial thinking, if something doesn't work, it must be replaced with another type. Perhaps a biological valve can be used to avoid the same problem.
However, there is never such a simple mental path map to refer to when solving medical problems.
First, let’s review why this patient chose a mechanical valve for his first surgery?
The doctor who performed the operation for the first time should have known that the patient was a young woman who wanted to get pregnant. Mechanical valves require long-term use of anticoagulants such as warfarin after surgery, which can easily cause blood clots and affect women's pregnancy and childbearing. These shortcomings indicate that mechanical valves should not be the first choice for this young woman in need.
Like this patient, due to the special hypercoagulable state during pregnancy, blood clots formed in the mechanical valve and blocked the valve opening, necessitating another surgery urgently.
Does this mean that the doctor who performed surgery on a patient for the first time was inconsiderate to the patient?
On the contrary, before the operation, cardiac surgeons will routinely introduce various valves to patients. In other words, as long as the patient's physical condition allows, the patient can decide which valve to install. The reason why patients are allowed to make the choice first is that they have their own economic interests in the cost of medical treatment. How much money patients are willing to spend on their own medical treatment is not something that doctors can decide for them.
