There was a problem with the original mechanical valve. If the same mechanical valve is replaced, the doctor has to be more careful.
A significant disadvantage of mechanical valves is that they are not as compatible with the human body as biological valves. Surrounding tissue can easily proliferate and affect the operation of the mechanical valve, causing stenosis again, which is a headache for doctors.
When the surgeon removed the previous mechanical flap, typical hyperplasia tissue was found.
When a new mechanical valve is connected to the patient, the connection part needs to be repaired. It is best to avoid the same situation from happening next time.
Whether a surgery is done well or not depends on the doctor's skills in these details.
You can just make do with lowering a flap and it will work anyway, or you can "finely polish" the joint to achieve a perfect fit.
As he was doing this, the chief surgeon, Dr. Du, suddenly stopped, threw the surgical instruments onto the nurse's instrument table next to him, and put his hands in the glove pockets on the chest of the surgical gown.
Du Yeqing's eyes behind his glasses looked very serious.
Surgeons each have their own style. Some doctors are very cheerful and think that it is almost enough. Anyway, the human body's own medical research is constantly progressing, and what is done now may be better. If the operation time is too long, it may be harmful to the human body. Overall disadvantage.
Du Yeqing is not the case. He is an extremely rigorous and conservative doctor who has high requirements for surgery. He believes that casual installation and implantation are not his principles for surgery. He is willing to spend more time thinking about it and must do it within the limit of time. Make the operation the most meticulous and close to perfection. Regardless of what the future of medical research holds, being a doctor means working hard under the current conditions and betting that he will not like the future.
Of course, his demanding requirements are not only for himself, but will also put greater pressure on others.
For such a surgeon, the most disliked thing is the auxiliary staff in the operating room.
Other assistants would never dare to follow the surgeon's lead and stand by with surgical instruments to respond to the surgeon's orders at any time.
"I don't know how long the operation will take now." Du Meng sighed secretly.
Zhang Shuping didn't answer. Cardiac surgeries are notoriously long, and that's why.
When implanting things in other parts of the human body, it is necessary to carefully consider the needs of the whole body like in the heart.
The cardiopulmonary bypass doctor and the anesthetist became a little nervous when they saw that the surgeon was not moving, and they needed to consider the occurrence of extreme situations.
The expression on Shen Youhuan's face became more serious as he stood at the door. He might be wondering whether he should go back to Zhang Huayao and take a look.
Zhang Huayao went to see the patient's family first after the child was born. The safe birth of the child is equivalent to more than half of the task completed, and 20 million can be obtained. This must be a joke. Zhang Huayao left because the next cardiac surgery was his own The doctors at the hospital know the basics, so there is no need for them to worry too much.
The operation was at an impasse.
At this moment, no one in the operating room thought about dinner.
His stomach growled, and Du Meng'en felt like he was going to be hungry and dizzy, so he didn't dare to complain about hunger.
Finally, the surgeon on the operating table murmured: "Tell me, what is the problem?"
Several assistants gathered around to help the surgeon think about the problem. To be honest, if he could really think of it, the first assistant and the second assistant would have spoken up long ago, so why delay it until now. It seems that Ye Qing is not just asking the assistants on the operating table, but asking Everyone in the operating room watching the operation.
