Chen Cang felt the thickness of the patient''s skin burn and the existence of phloem with his hand


    Then the knife in your hand is very light, three points into the skin, slightly force, and gently cut along the trailing edge of sternocleidomastoid muscle, reaching as deep as platysma.


    This knife is very accurate!


    Perception: the effect of + 30 has been brought into full play!


    After accurately passing through the phloem tissue, reach the depth of platysma!


    No increase, no decrease.


    The resistance of the knife in different tissues is well grasped!


    After a little thought, Chen Cang cut open the platysma membrane to completely release the pressure of circular eschar!


    Sure enough, after this knife was cut, the patient''s breathing immediately became smooth!


    After escharectomy, all you have to do is escharectomy!


    Of course, many mild patients do not need to cut and peel scabs!


    Because eschar can be separated naturally!


    But this process is also dangerous. It is a process of eschar infection, dissolution and liquefaction.


    In this process, the body consumes a lot, the inflammatory reaction is heavy, and the infection is aggravated. In order to shorten this process, surgical removal can be used, which is called expanding wound, also known as escharectomy!


    This step must be carried out under anesthesia!


    Because the scalpel and saw need to be separated along the deep surface of necrotic tissue to remove eschar!


    The people nearby can''t help at all!


    Even Gong Daizhen can only help a little. Chen Cang needs to do it all by himself!


    Because even Chen Cang can''t guarantee how to minimize the surgical stimulation!


    Under anesthesia, the patient''s body has felt stimulation.


    At this time, Chen Cang held a knife in his left hand and a scissors in his right hand.


    But


    But like no weight!


    you ''re right!


    Chen Cang carefully cut the knife into the deep surface of necrotic tissue and began to separate and remove eschar!


    Then, when the right hand sees the scattered necrotic tissue or exposed unhealthy adipose tissue remaining in the wound base, cut it off... Or scrape it gently.


    This process needs to be carried out layer by layer!


    It''s best not to stimulate too much.


    Don''t damage too much!


    The knife and scissors in Chen Cang''s hand seemed to be as weak as a cotton stick wrapped in cotton!


    Look at the eyes of the people around you!


    This is a very difficult operation in the operation. If you use the martial arts realm to describe it, it must be: lifting heavy as light and complex as simple!


    you ''re right!


    How difficult is it to think about using sharp knives such as scalpels and scissors with the same effect as cotton balls?


    Because only in this way can we not damage too many normal tissues!


    No one knows the depth of the burn and the thickness of the scab!


    This seemingly simple scene, watching everyone excited!


    Gong Daizhen at the scene looked at Chen Cang and sighed!


    I thought the gap between myself and Professor Chen would be smaller and smaller.


    Even if there is, it should also be inspiration and method, and the operating skills may not be too different!


    But this set of operation really frustrated her!


    Because at this height, she knows very well that she has passed the peak of operation improvement, and it will be difficult to catch up for the rest of her life!


    Qin Xiang and Yang Tao looked at each other!


    I saw fear and fear in each other''s eyes!


    Sweat left from the two men''s hands and soaked the green clothes inside.


    But Chen Cang did not dare to relax at all!


    Finally, less than two minutes later, the normal tissue was finally revealed!


    Chen Cang glanced at Gong Daizhen: "clean!"


    He doesn''t want to talk now. This operation has just begun!


    Six hours of operation, in the high temperature of 32 degrees, my full name needs the main knife. If you can save some strength, just save a little!


    Fortunately, Gong Daizhen is quite reliable!


    Skillfully wash repeatedly with 1% hydrogen peroxide, normal saline and metronidazole to stop bleeding completely.


    After that, we need to take autologous skin source for transplantation!


    The skin needs to be collected on site to retain the activity of the skin as much as possible.


    And this skin comes from Zhao Yasi''s leg!


    "Director Qin, get ready to take the skin!"


    Qin Xiang nodded and looked at Zhao Yasi, ready to start!


    Peeling needs to be done with a roller knife!


    Zhao Yasi lay on one side of the bed, very nervous, very nervous!


    But as long as she can save her father, she will!


    Qin Xiang didn''t say anything more. Chen Cang is waiting. We can''t delay.


    While talking, the roller knife passed and a piece of skin was taken away!


    Exposed a bright red, it looks very ferocious!


    Yang Tao hurriedly prepared to clean up, and then began to sew up Zhao Yasi''s legs!


    The skin needed for the neck is not very big, but skin grafting is very difficult!


    How to find blood supply pedicle for pedicled blood vessels!


    In fact, there are not many blood vessels available at this time!


    However, we must also ensure the success rate of skin transplantation and take into account the efficiency of skin graft in the future


    Time goes by!


    Chen Cang dare not be careless.


    Every step is being taken seriously!


    It took nearly an hour, and the circular eschar on the neck was finally treated!


    Next is the circular eschar on the chest!


    The skin area here is three times larger than the neck!


    The difficulty increases proportionally!


    The surgical incision starts along the bilateral axillary front line!


    Slowly cut along 2cm below the clavicle to the 10th rib!


    Originally only need to reach the tenth rib!


    But... Chen Cang suddenly frowned. He found that the patient was actually chest and abdomen eschar!


    In this way, we must continue.


    Because men are abdominal breathing!


    Chen Cang can only continue to cut along the rib margin. Both ends of the incision meet with the bilateral axillary front incision. The depth of the incision should reach the deep fascia!


    The whole incision is long!


    But the effect is remarkable. At least the patient''s breathing is much better.


    Escharectomy... Escharectomy... Skin grafting


    Every step is going on!


    But the remaining 20% of the patient''s skin is not enough to support so much!


    This needs to test the ability of the chief surgeon!


    How to fill the 20% skin in the 50% area!


    Very difficult, very high!


    Chen Cang''s brain is like a high-speed computer, constantly starting to calculate, decompose, calculate and test


    Time goes by!


    Chen Cang felt himself in the steamer!


    Sweat wet his underwear again and again.


    There is no chance to dry from beginning to end!


    Because it''s too hot!


    Like a steamer!


    And the passage of sweat is like dehydration!


    Gong Daizhen was a little distressed.


    Not only her, but also the doctors, nurses, anesthesiologists and medical departments around her... They looked at Chen Cang with awe!


    This is really a good doctor!


    Just this determination, we should praise him!


    And now!


    Zhao Yasi, who was lucky to watch the operation on site, saw this scene!


    Professor Chen''s operating suit was tightly attached to his back, and sweat had even wet the ground around Chen Cang on the ground of the operating room.


    But... Even so, he didn''t move!


    Suddenly, Zhao Yasi burst into tears!


    At this moment, she finally understood that Professor Chen had resolutely promised his back!


    What is it?


    It''s pressure! It''s responsibility! It''s hard! It''s also a promise!
