Chapter 341 [341] The teacher gave a chance


    Xie Wanying cut the thread in her hand and cut off the extra stitches.


    The nurse opposite ?? wiped the sweat from the forehead of the chief knife again.


    In contrast, Xie Wanying''s face was trained for a long time, without a drop of sweat, it looked like a frozen object. The nurse and the anesthesiologist nced at her face.


    It is impossible to say that she is not panicking. The teacher did not inform her in advance and told her to prepare herself mentally, and suddenly calling her a helper made her a little panicked, which Xie Wanying admitted. Even though she has seen many scenes where a teacher is a helper and knows what a helper is going to do, it always takes some time to get used to it. Fortunately, her quick-reacting brain took her hand, and she got used to it.


    Halfway through the operation, the nurses and the anesthesiologist breathed a sigh of relief. The sound of the pointer in the operating room was reduced, and the reprimand was reduced to zero.


    Near the end of the surgery, this time the teacher gave her a chance to practice another suture method.


    Because the patient was thin and weak, the clinical teacher decided to use full-thickness dpression suture for the patient.


    "Do you know how to sew?" Teacher Sun asked.


    Xie Wanying reacted quickly, took care of the bed herself, and replied, "Mr. Tan sewed 3 bedsst time."


    This student often steals from his teacher. The single eyelid under Tan Kelin''s eyebrows was thin and cold, and his eyes were lowered. Only the pointer pliers he held in his hand turned around in his palm, which could reveal a little bit of his funny and inexplicable mood.


    "You shouldn''t have said much in your medical books." Sun Yubo recalled the textbooks he had studied before.


    A textbookpiled every few years can keep up with the rapid development of medicine. Some of the knowledge in the book is often outdated and impractical when ites to the clinic. Otherwise, how can it be repeatedly emphasized that medical students should have enough internship time before graduation.


    Doctor is a practical technical profession, stitching is more than embroidering on a book.


    "Since you''ve seen Mr. Tan sew before, you can try it." Sun Yubo answered without the student, knowing that the student''s endorsement is too slippery and there is no need to test this.


    Xie Wanying had no choice but to nod her head, revisiting the main points of knowledge first in her mind.


    Like the skin sutures that she practiced a few times, it belongs to oneyer ofyered sutures.


    Surgery opens the patient’s abdominal cavity, and severalyers of tissue need to be opened to ess the organs, including the skin, subcutaneous, fascia, tendon, muscle, peritoneum, etc. These open tissues are re-sewed and closed at the end of the surgery. In this way, ayer of skin is sutured, ayer of fascia is sutured, ayer of tendon is sutured, ayer of peritoneum is sutured, and so on, which is calledyered suture.


    Compared withyered suture, full-thickness suture, as the name suggests, bes a suture of severalyers of skin and fascia.


    This patient is malnourished. If theyers of sutures are not necessarily able to promote wound healing, it will defeat the purpose of sutures, causing the exudates in the body to be unable to effectively overflow or be absorbed, increasing the chance of infection. It is not as good as severalyers of sutures. The sutures are used to pull the tissue closer and align, and the final healing depends on the patient''s own tissue growth and the sutures.


    Dpression suture is the same principle, the thin patient has less fat, the sutures stretch the tissue too tight, and the scarring is more ugly like a centipede. Such patients tend to have high intra-abdominal pressure, high tissue tension, and a severe cough can easily copse the sutures. To this end, it is necessary to reduce the pressure of the incision and increase the distance between the needle entry point and the needle exit point and the incision, which is vividly called dpression suture.


    So, this patient is like 3 beds, and even the peritoneum is not sutured.
