Xie Wanying cut the thread in her hand and cut off the extra stitches.
The nurse opposite wiped the sweat from his forehead again on the main surgeon.
In contrast, Xie Wanying's face was scolded for most of the day, without a drop of sweat falling down, and it looked like a frozen object. The nurse and anesthesiologist glanced at her face.
It is impossible to say that she is not panicked. The teacher did not inform her in advance and asked her to be mentally prepared. Suddenly calling her to be accustomed to her was a little panicked. Xie Wanying admitted this. Even though she had seen the teacher as a cicada many times, she knew what Ichisuke was going to do, it always took some time to adapt. Fortunately, her brain, which quickly reacted, was adapting with her hands.
The nurses and the anesthesiologist breathed a sigh of relief in the second half of the operation. The sound of slapping in the operation room was less, and the sound of scolding decreased to zero.
As the operation ended, the teacher gave her the opportunity to practice another method of suture.
Because the patient was thin and had weak constitution, the clinical teacher decided to use full-layer decompression suture for the patient.
"Do you know how to sew?" Teacher Sun asked.
Xie Wanying quickly reacted and said, "Teacher Tan sewed three beds last time."
This student often steals his teacher. Tan Kelin's single eyelids under his eyebrows were thin and cold knife with his eyes lowered. Only the whip in his hand turned around in his palm, which could slightly reveal his mood that was both funny and unknown how to describe it.
"You probably didn't talk much about it in medical books." Sun Yubo recalled the textbooks he learned before.
Textbooks compiled every few years can keep up with the ever-changing development of medicine. When some knowledge comes to clinical practice, it is all outdated and unpractical. Otherwise, why do you repeatedly emphasize that medical students need enough internship time before graduation?
Doctors are in the practical technology industry, and stitching is not embroidered on books.
"Since you have seen Teacher Tan sew it, you can try it." Sun Yubo answered without taking the exam, knowing that the student in front of him was too sensible to memorize this student.
Xie Wanying had no choice but to nod and revisit the key points of the knowledge in her mind for a moment.
Like the skin stitching she practiced several times last time, it is one of the layered stitching.
When the surgery opens the patient's abdominal cavity, several layers of tissue need to be opened to the organs, including the skin, subcutaneous fascia, tendons, muscles, etc. These open tissues must be closed again after the operation. In this way, the skin sewing is layered, the fascia sewing is layered, the tendon sewing, and the peritoneal sewing are layered, etc., called layered suture.
Compared with layered suture, full-layer suture becomes a stitch of several layers of skin fascia, as the name suggests.
The patient in front of him is malnourished. If the layers of seams may not necessarily promote wound healing, it violates the purpose of suture, causing the body's exudates to not be effectively overflowed or absorbed, increasing the chance of infection. It is better to have several layers of seams. The sutures pull the tissue closer and aligned, and the final healing depends on the patient's own tissue growth and sutures.
The same principle is for decompression suture. Patients with thinning have less fat, the sutures pull the tissue too tightly, and the scars are more ugly like centipede-like. Patients often have large abdominal pressure in the abdominal cavity and high tissue tension. A severe cough can easily break the suture. To this end, the pressure of the incision is reduced, and the distance between the incision point and the incision point is increased. It is vividly called decompression suture.
