Although it is a simulated competition, the simulator is very sensitive in feeling blood pressure and blood volume!


    This will undoubtedly increase the difficulty of the game!


    People and simulators look the same, but there are great differences in essence. The failure judged by simulators is very intuitive. Once the value changes, it is failure!


    However, the existence of human compensation mechanism and self rescue mechanism will lead to many miracles.


    Sims don''t!


    When Chen Cang saw the situation in his chest, some of his scalp felt numb.


    No wonder we should choose a unified operation, because such an operation is very representative.


    Just like this time!


    Multiple injuries of vena cava, accompanied by direct rupture of ascending aorta and innominate artery arch, resulting in multiple bleeding!


    The alarm sound on the ECG monitor reminds Chen Cang all the time.


    Blood pressure is 10070!


    Seemingly safe blood pressure, but so many large blood vessels break, it won''t be long before the blood pressure will drop to a very dangerous value!


    Chen cangmei''s heart is tight!


    How to choose surgery has become a very difficult problem.


    In general, blood flow blocking is necessary for active injury and innominate artery injury!


    However, the blood flow of vena cava can not be blocked directly. When repairing its injury, only noninvasive vascular forceps can be used to clamp the tube wall partially, or under internal shunt.


    At the same time, because the vena cava is seriously damaged, the long-term embolization rate of vein graft is high, so it should not be used!


    But at this time, the vascular damage is very serious!


    How to choose?


    Looking at the box of the simulated cardiopulmonary bypass machine, Chen Cang was lost in thought.


    If the cardiopulmonary bypass machine is used, it is obvious that the operation time will be prolonged.


    However, the vein injury is so serious that it can not block the blood flow, so it is not suitable to use vein transplantation.


    Injuries at the ascending aorta and innominate arch need to be treated quickly.


    At this time, blocking becomes very troublesome. If the vascular bypass is constructed, it will undoubtedly aggravate venous bleeding


    In a few seconds, Chen Cang has been thinking about many ways!


    Finally, Chen Cang looked at the ECG monitor and suddenly had an idea!


    Yes!


    Blood pressure is still 100!


    What are you afraid of?


    Direct recklessness!


    Thinking of this, Chen Cang decided to do a bold thing.


    ……


    ……


    At this time, on the stage outside, several experts sat together, and the operation video was on the big screen.


    Sitting in the audience were some doctors in the field of cardiothoracic surgery, as well as postgraduates and advanced students.


    The host smiled and said, "to tell you the truth, I am very excited every time the national skill competition of cardiac surgery, because I can see the continuous rise of batch after batch of young cardiac surgeons, take over the baton in the hands of the older generation, and become the leader and mainstay in our surgical field!"


    "Now that the operation has begun, I believe you can''t wait. Let''s give our voice to experts and let them comment on the operation."


    In fact, they have a list of seed players in their hands.


    Soon the video switched to an operating room in a room.


    There was a lot of discussion in the audience.


    After seeing the picture, Li Wenbin immediately said, "to tell you the truth, I just saw the competition topic. It''s a little difficult. It should be a car accident injury, multiple vena cava injuries, accompanied by the contusion and laceration of the isthmus of the ascending aorta and the tear of the innominate Arch!"


    "You can see that the wounds of the superior vena cava and the left and right superior pulmonary veins are very big!"


    "It''s very difficult this year! What do you think, Professor Yang?"


    Everyone frowned when they saw the picture.


    Yang Guangdong nodded: "yes, this year''s competition is much more difficult than last year, but this is a trend. Changing a simple operation into a systematic operation increases the difficulty, but it can better reflect the operator''s ability and avoid some partial doctor coincidence scores."


    "But... This operation is very challenging. There are many injuries in arteries and veins. How to choose the operation method and rhythm is particularly important!"


    "Hey? This candidate is very good, a very stable operation. He chose the extracorporeal circulation machine, took the lead in dealing with the artery, and narrowed the opening of venous bleeding with non-invasive hemostatic forceps. In this way, the blood pressure should not decrease too quickly while blood transfusion!"


    "Very! The surgical skills are also very skilled. Just looking at these operations, there should be no problem in promoting!"


    The director smiled and said, "well, on the screen is Ding Yu from Anzhen Hospital. Thanks for the 50000 reward of" book friend 20171208063955163 "in last year''s final, plus more!


    Thank you: "PLA Hao" brother''s 15000 reward, and thank "half rose" for 10000 reward.


    Thank you for the 10000 reward of "sugar is not sweet", miss.
