439 Successful skin grafting

The operation was completed and the injured was pushed out of the operating room.

After a while, the injured person woke up.

"Doctor, how about my feet? I haven't been amputated, right?" The injured person asked immediately when he saw Su Yang, very anxious.

"No." Su Yang nodded.

"Really? Doctor, you didn't lie to me?"

"I really didn't lie to you!" Su Yang replied with a smile.

He didn't know the patient, but he just knew that the other party was named Zhang Yong, who was a soldier in an armored unit.

He was still a little worried about the injured person because his identity was a bit special. Generally speaking, if a person with this identity knew that he was seriously injured, he would be dead and would be afraid that he would collapse. But he did not expect that the injured person could ask such a question.

It is very good for the patient to perform like this, and in this way, the subsequent work will be easy to carry out.

He squatted down in front of the injured bed and said softly: "Your feet are saved, but if you want to recover, there is still a very long way to go, and it is a very painful road. It is no easier than on the training ground. Comrade Zhang Yong, do you have confidence?"

The guy was stunned, then nodded quickly: "Yes, doctor, as long as I can get better, as long as I can get back to the army, no matter how much suffering I suffer or how much tired I suffer, I am not afraid!"

Su Yang was very satisfied with this answer. He smiled and said softly: "Okay, then I'll give you a briefing. My name is Su Yang. You may not know my name..."

As soon as Su Yang finished speaking, Zhang Yong was excited: "You are Su Yang? I know you, I have heard of your name..."

He was excited to say something, but soon, he reacted and swallowed the words back into his stomach, just looking at Su Yang with his shiny eyes.

Su Yang patted him: "So, have confidence in me!"

"Thank you Dr. Su! Thank you Dr. Su! With you in charge of my treatment, I am full of confidence in my future!"

At this moment, Su Yang's heart finally fell to the ground.

If the patient is willing to cooperate and the patient is full of confidence in their treatment, it will be easy to deal with. Next, the treatment can be carried out step by step.

Zhang Yong's treatment is quite troublesome and takes a long time. Moreover, because the crushing is serious, it is very difficult to recover!

Fortunately, Su Yang has a system, so he can perform experimental treatment in the system space and use the exclusion method to find the best way.

On this day, he was thinking about Zhang Yong's rehabilitation training plan, and the head nurse Yang Juan suddenly walked in hurriedly.

"Director, something went wrong with Zhang Yong." Yang Juan said with some concern.

“What’s the problem?”

“VSD    The material has changed color.”

Su Yang was stunned for a moment.

This situation did not occur in previous experimental treatments.

In previous experimental treatments, he simulated what could happen in three or four cares.

The first type is that the drainage pipe is blocked.

Regarding the handling of this situation, he had already told the head nurse that he could slowly inject saline into soaking in reverse. After the blocked drainage material became soft, the negative pressure source should be turned on again. If necessary, multiple operations are required, and even the VSD material should be replaced.

In addition, there are two situations: VSD     The dressing is bulging, the tube shape is invisible, and VSD    The material is dry and hardened.

Regarding the situation where the dressing is bulging and the tube type cannot be seen, he has analyzed the common reasons for the head nurse. In addition to the blockage of the drainage tube, the abnormal negative pressure source, the suction machine failure, the damage to the central negative pressure gauge head, the air leakage at the interface, the power outage, the central negative pressure stop, the drainage tube being compressed, folded, etc. The cause should be found in time and given corresponding treatment.

As for VSD    The material becomes dry and hard. As before   48                                                                                                                                                                                                                                                 

But in reality, neither of those two situations occurred, but another situation occurred.

It seems that in reality, the patient's condition has changed.

After thinking for a while, Su Yang said to the head nurse: "VSD    There is a little necrotic tissue and ooze residue in the material, and sometimes it emits a odor through the semi-permeable membrane, and even filthy colors such as yellow-green, gray-dark color appear on the material. This is not caused by necrotic tissue on the wound and will not affect the treatment effect of VSD. There will be no special treatment for the time being."

“Not dealing with it?”

"Yeah!" Su Yang nodded and then said: "What you need to closely observe now is whether fresh blood will be sucked out. When you find that a large amount of fresh blood is sucked out, you should immediately notify the doctor on duty to carefully check whether there is active bleeding in the wound and do the corresponding treatment."

"Okay, I know what to do!" The head nurse hurried out.

Su Yang picked up various information about the patient and read it again. Then he resimulated the relevant treatment in the system space. After finding the best solution, he breathed a sigh of relief. He made a little modification to the subsequent treatment, but the overall idea did not change.

Studies have shown that negative pressure sealing attraction plays an important role in the repair and healing of wounds.

Negative pressure blocking drainage can dilate capillaries, promote blood vessels and granulation hyperplasia, strengthen the connection between endothelial cells, promote the recovery and integrity of the vascular base membrane, thereby improving wound microcirculation, conducive to wound healing, and significantly shortening the treatment time.

Soon, the patient had exposed tendons on the back of his foot and grew well.

Su Yang began transplant surgery.

The first step is to do wound treatment first.

Scrape the granulation tissue with a blade, but avoid scraping the granulation tissue too thin. Then trim the skin around the wound to form fresh wounds and trim it into a steep edge to facilitate the growth of the skin grafting sheets and normal skin.

When measuring the size of the wound, it is expected that the size of the skin is required. The wound is disinfected with iodine, then rinsed with normal saline, and wet gauze to prepare for use.

Afterwards, the skin transplantation was performed.

Medium-thick skin slices (thickness 0.3 ~ 0.6mm) are cut into the skin donor area of ​​the inner thigh or lower abdomen, lateral abdomen, etc. The skin slices can be directly sutured, and the skin slices on the inner thigh are covered with thick dressings and pressed; the skin slices are evenly covered on the skin defects of the foot, fixed with sutures between the skin edges and the skin slices, and then pressed or locally packed and pressed. After the operation, remove the dressings and change the dressings to observe the survival of the skin slices.

After the operation, all the skin pieces survived and the donor area was healed in the first phase. After the operation, the skin texture was medium, not bloated, and the skin was slightly pigmented.

The treatment was very successful.
