Xie Wanying trimmed the thread in her hand to cut off the excess thread.
The nurse on the opposite side wiped the sweat from the chief surgeon's forehead again.
In contrast, Xie Wanying's face was scolded for a long time, without a single drop of sweat, it looked like a frozen object. The nurse and the anesthetist glanced at her face.
It's impossible to say she didn't panic. The teacher didn't inform her in advance to tell her to be mentally prepared, and suddenly asked her to be a helper made her a little flustered, which Xie Wanying admitted. Even if she has seen the scene of the teacher being the first assistant many times and knows what the first assistant will do, it still takes some time to get used to it. Fortunately, her quick-reacting brain and her hand have adapted.
In the second half of the operation, the nurses and anesthetist breathed a sigh of relief. The sound of cracking pointers in the operating room was reduced, and the sound of reprimands was reduced to zero.
Near the end of the operation, this time the teacher gave her the opportunity to practice another suture method.
Because the patient was thin and weak, the clinical teacher decided to use full-thickness decompression suture for the patient.
"Do you know how to sew?" Teacher Sun asked.
Xie Wanying quickly realized that she managed the bed herself, and replied, "Teacher Tan sewed three beds last time."
The student often steals his teacher. The single eyelid under Tan Kelin's eyebrows was thin and cold, and the eyes were drooping. Only the pointer pliers in his hand turned around in his palm, which could reveal his amused and undescribable mood a little bit.
"You probably haven't mentioned much in your medical books." Sun Yubo recalled the textbooks he studied in the past.
How can textbooks compiled every few years keep up with the ever-changing medical development. Often some knowledge in books is outdated and impractical once it comes to clinical practice. Otherwise, why do you repeatedly emphasize that medical students need enough internship time before graduation.
Doctors are practical and technical professions, and sewing is not embroidery on books.
"Since you've seen Mr. Tan sew, you should try it." Sun Yubo replied that the student didn't take the test, knowing that the student in front of him was too slippery to memorize and there was no need to take the test.
Xie Wanying could only nod her head, revisiting the main points of knowledge in her mind for a moment.
Like the skin stitching she practiced a few times last time, it belongs to one layer of layered stitching.
The operation opens the patient's abdominal cavity, and several layers of tissue need to be opened to reach the organs, including the skin, subcutaneous fascia, tendon, muscle, peritoneum, etc. These opened tissues will be re-sewed and closed after the surgery. In this way, one layer of skin, one layer of fascia, one layer of tendon, one layer of peritoneum and so on are called layered suture.
Compared with layered suture, full-thickness suture, as the name suggests, becomes a suture of several layers of skin and fascia.
The patient in front of him is malnourished. If the layers of stitches are not necessarily able to promote wound healing, but contrary to the purpose of stitching, the exudate in the body cannot be effectively overflowed or absorbed, increasing the chance of infection. It is better to suture in several layers. The sutures pull the tissue closer to the alignment, and the final healing depends on the patient's own tissue growth and has nothing to do with the sutures.
The principle is the same for decompression sutures. Thin patients have less fat, and the sutures pull the tissue too tightly, and the scar hyperplasia looks like a centipede, which is even more unsightly. Such patients often have high intra-abdominal pressure and high tissue tension, and a severe cough can easily break the sutures. For this reason, the pressure on the incision should be reduced, and the distance between the point of entry and exit of the needle and the incision should be enlarged, which is vividly called decompression suture.
Therefore, this patient is like a 3-bed surgery, even the peritoneum is not stitched.
