Xie Wanying clicked the thread scissors in her hand to cut off the excess sutures.
The nurse on the opposite side wiped the sweat from the surgeon's forehead again.
In contrast, Xie Wanying's face had been trained for a long time without a drop of sweat. It looked like a frozen object. The nurse and anesthetist glanced at her face.
It's impossible to say that she didn't panic. The teacher didn't notify her in advance to prepare herself mentally. She was a little panicked when she was suddenly asked to be the first assistant. Xie Wanying admitted this. Even though she had seen the teacher become the first assistant many times.
She knew what Isuke was going to do, but it always took some time to adapt. Fortunately, her quick-response brain and her hands helped her adapt.
Halfway through the operation, the nurses and anesthesiologists breathed a sigh of relief. The sound of the pointer snapping in the operating room was reduced, and the scoldings were reduced to zero.
Near the end of the operation, the teacher gave her the opportunity to practice another suturing method.
Because the patient was thin and weak, the clinical teacher decided to use full-thickness decompression suture on the patient.
"Do you know how to sew?" Teacher Sun asked.
Xie Wanying quickly realized that she was in charge of the bed and replied: "Teacher Tan sewed three beds last time."
This student often steals from his teacher. The thin-lidded single eyelids under Tan Kelin's eyebrows are drooped down. Only the pointer pliers in his hand are turning in his palm, which can slightly reveal that he is both funny and hard to describe.
Feeling.
"You probably haven't mentioned it much in your medical books." Sun Yubo recalled the textbooks he studied in the past.
Textbooks compiled every few years cannot keep up with the rapid development of medicine. Often some of the knowledge in the books is outdated and impractical once it comes to clinical practice. Otherwise, why would we repeatedly emphasize that medical students should have enough internship time before graduation?
Doctors are a practical technical profession, suturing is not embroidery on books.
"Since you have seen Teacher Tan sew, you can try it." Sun Yubo answered without taking the test, knowing that the student in front of him was too good at memorizing and there was no need to take this test.
Xie Wanying could only nod, reviewing the key points of knowledge in her mind all the time.
The skin suturing she practiced the last few times was one of the layers of layered suturing.
Surgery opens the patient's abdominal cavity, and several layers of tissue need to be opened to reach the organs, including the skin, subcutaneous fascia, tendons, muscles, peritoneum, etc. These opened tissues need to be re-sutured and closed after the operation is completed. In this way, one layer of skin is sutured and one layer of fascia is sutured.
, the tendon is sutured in one layer, the peritoneum is sutured in one layer, and so on, which is called layered suturing.
Full-thickness suturing is different from layered suturing. As the name suggests, it becomes several layers of skin, fascia and so on.
The patient in front of me is malnourished. If layer by layer of suturing is done, it will not necessarily promote wound healing. Instead, it will defeat the purpose of suturing, causing the exudate in the body to be unable to effectively escape or be absorbed, increasing the chance of infection. It is better to sew in several layers and sew together.
The threads bring the tissues closer into alignment, and the final healing depends on the patient's own tissue growth and has nothing to do with the sutures.
The principle of decompression suturing is the same. Obese patients have less fat and the sutures pull the tissues too tightly, resulting in scar hyperplasia that looks like a centipede and is more unsightly. Such patients often have high intra-abdominal pressure and high tissue tension, and a severe cough can easily collapse the sutures.
To this end, it is necessary to reduce the pressure on the incision and increase the distance between the needle entry point and the needle exit point and the incision, which is vividly called decompression suture.
Therefore, this patient was in bed 3, and even the peritoneum was not sutured.
