Pure doctor Wu Xie

Chapter 3 People's Words Are Frightening (for collection, for follow-up reading)

Lidocaine and sterile saline should be used together. Simple epidermal damage does not require such a high concentration of 2% lidocaine. This is the most basic basic skill.

Wu Xie's professional knowledge reserve is not enough, but he can learn knowledge other than professional knowledge quite quickly.

Before the anesthesia was given, Wu Xie said: "Madam, the anesthesia will hurt a little at first, just bear with it for a while, and it will be fine soon, just one injection will be more painful."

Xu Huifang was disdainful: "When I was cut, I felt it was just such a painful way, you give me an injection..."

"Ouch."

Xu Huifang's hands shook slightly, her voice stopped abruptly, she looked at Wu Xie, then at her own hand, her expression stiffened.

In fact, Wu Xie only injected a small Pichu, and started to inject after withdrawing, and the pain was relieved immediately.

"Ma'am, the pain sensitivity of the surface layer of the skin is much higher than that of the inner layer. When the skin surface is scratched and the skin is tested, the pain is severe."

"A deep needle, or a deep cut, doesn't hurt too much."

Wu Xie repeated the basic skills of the conversation he had heard from his senior brother before, and patiently explained.

This is the reason why the skin test is much more painful than the intravenous injection.The skin is a sensitive receptor.

"To read a lot means to know a lot. I don't know these things." Hearing Wu Xie's gentle voice, Xu Huifang's smile bloomed again.

In my heart, I once again defined Wu Xie as a high-quality outstanding young man.

Wu Xie didn't reply anymore, and gradually deepened the local anesthesia to prepare for the suture later.

After anesthesia, Wu Xie continued to explain: "Madam, the pain is gone, don't be nervous when I sew, don't move, or I won't be able to operate."

"Don't worry, I won't move." Xu Huifang slightly adjusted her sitting posture and raised her hands higher.

And just when the needle was about to drop, Wu Xie found that there was something more in his mind.

Before, Wu Xie's understanding of suture was the content of the basic operation of surgery, mainly some key points.

The needle insertion point is about 0.5cm away from the incisional edge, and the needle is inserted vertically, and the depth of the needle is about 0.5cm. Then, when it is in the incisional edge, it must pass through the incisal edge vertically, and then exit the needle vertically, 0.5cm away from the incisal edge.

Equivalently, the distance between the needle entry point and the needle exit point is 1cm, the distance between each thread knot is 1cm, and then the length of the thread left when cutting the thread is 1cm.

However, in hand surgery, this distance can be relatively reduced to about 0.3 or 0.2cm...

Moreover, when stitching, the stitching level is also something that needs attention.

This has to return to anatomy again. The anatomy of the skin is actually divided into three components: the epidermis, the dermis, and the subcutaneous tissue.

Among them, most of the capillaries are deformed in the subcutaneous tissue. Therefore, when suturing, the depth must be mastered.

Under the subcutaneous tissue, there is also a subcutaneous fascia.

The suture depth just reaches the subcutaneous fascia, which can lock the small blood vessel damage in the incision and achieve the effect of hemostasis, and don't worry, the large blood vessels, rather the arteries and veins of the dorsal fingers are sutured, which will affect the blood supply near the wound.

……

After suturing, Wu Xie said, "Ma'am, let go of your hand first, and see if it bleeds again?"

Wu Xie looked at his stitched work, and felt that the quality of stitching this time was far superior to any previous one.

After Xu Huifang let go of her hand, she didn't see any blood oozing out.

Moreover, what Wu Xie judged was whether the blood supply at the distal end was normal. If the radial artery or the dorsal digital artery were sutured, the distal end would become black due to ischemia.

Or after the vein is sutured, it will swell up and the blood return will be blocked.

But it is obvious that none of this exists. If you control the depth of stitching, you know where your stitching level is, and you don't panic at all. This is the confidence brought by knowledge.

It seems to be just a glance, but the whole thing is already clear in my heart.

"It's all right, ma'am, it's finished. After you go back, don't get wet. Come over to change your dressing in two or three days. I'll prescribe some oral medicine for you later, and you can go back with another tetanus shot."

"Remember not to get wet." Wu Xie explained carefully.

Xu Huifang nodded quickly: "Then I will definitely listen to you."

At this moment, at the door of the operating room, a white coat in his 50s rushed in while wearing a mask.

"Director Lu!" He had just entered, and Xu Huifang, who had gotten along well with Wu Xie and had a good attitude, quickly cut off the conversation.

Standing up to meet him, he stretched out his hand and showed it to the other party.

"Look at my wound, has it been treated?"

Wu Xie didn't say much, and raised her hands, maintaining a sterile posture.

Lu Junyin is the only deputy senior in the department, and one of the few deputy senior titles in Xuan County Hospital of Integrated Traditional Chinese and Western Medicine.

After carefully examining Xu Huifang's sutured wound, his eyes flashed slightly!
The stitching of this wound is very beautiful, the stitching point and the stitching point are like two kinds of staplers, and the stitching of the skin is also neat and uniform, without unevenness.

No bleeding, no redundant skin bumps.

This level of stitching is okay.

Lu Junyin glanced at Wu Xie, and explained with a smile: "Sister and brother, what are you worried about?"

"Little Xie was brought up by us. You don't know how reliable he is. Don't worry about him taking care of it for you?"

Lu Junyin is 55 years old, five years older than Xu Huifang.

Xu Huifang's family runs a noodle restaurant, which is opposite the town health center, and the two are very familiar with each other.

"Director Lu, how could I have such a meaning?" Xu Huifang was serious, with a serious tone, for fear that Wu Xie might misunderstand.

As fellow villagers, she and Xiang Mei are also very close, if this misunderstanding is sidelined to Xiang Mei, it may be difficult to get along with each other as friends in the future.

After reading it, Lu Junyin turned and left the operating room.

Wu Xie continued to bandage Xu Huifang, and explained her follow-up precautions, such as details such as pain at night after returning.

The nurse was standing there, Xu Rong saw Lu Junyin coming out, and asked nervously, "Director Lu, is there anything wrong inside?"

"Xu Rong, what are you talking about? It's just a small debridement, what can happen?"

"People's words are terrible, if you say too much, it will become a rumor!" Lu Junyin did not express his position directly, but the warning in his words was still obvious.

Xu Rong was a little shocked when she heard the words, wondering what the director meant.

Could it be that the rumors about Wu Xie in the town are just rumors?

But the last time Wu Xie was on duty?

Moreover, if Wu Xie is really pretty good, why is he coming to the town hospital?

What's more, Xu Rong asked specifically, Wu Xie was fired by the county hospital and sent to the town?

However, Xu Rong didn't think too much about it. Suturing is the most basic skill of surgery, and surgery is not just about suturing.

……

"Ma'am, your kitchen knife is not very clean. After sewing it up, you need to take some anti-inflammatory drugs. You don't need to be hospitalized after you're done." Wu Xie suggested to Xu Huifang after explaining the precautions after the operation.

The kitchen knife, when chopping meat, cuts the possibility of tetanus, and the chance of infection is also very high.

"This is to get some anti-inflammatory injections, I think so too." Xu Huifang nodded, for fear of wound infection.

Wu Xie then arranged Xu Huifang on his own bed, and then jumped when he saw the virtual panel in front of him.
