Chapter 3 People’s words are terrifying (please collect and read)

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 function.

Wu Xie's professional knowledge reserve is not enough, but he can learn knowledge outside of his major very quickly.

Before giving the anesthesia, Wu Xie said, "Honey, the anesthesia will hurt a little at first. Just bear with it for a little bit and you'll be fine soon. Just one injection will be more painful."

Xu Huifang was disdainful: "When I was cut, I felt it was only painful. You give me an injection..."

"Ouch."

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

Wu Xie actually only injected a small skin mound. After withdrawing it, he started injecting, and the pain was relieved immediately.

"Honey, the pain sensitivity of the surface layer of the skin is much higher than that of the inner layer. When you scrape the surface of the skin or do a skin test, the pain will be severe."

“It’s not particularly painful if you insert a deep needle or cut it a little deeper.”

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

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

"The more you read, the more you know. I don't know these things." Listening to Wu Xie's gentle voice, Xu Huifang's smile bloomed again.

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

Wu Xie didn't reply again, and gradually applied the local anesthesia deeply to prepare for the sutures that would be performed later.

After anesthesia, Wu Xie continued to explain: "Honey, the pain is gone, so don't be nervous when I sew it up, don't move, otherwise it will be difficult for me to operate."

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

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

In the past, Wu Xie's understanding of suturing was the content of basic surgical operations, mainly some key points.

The needle entry point is about 0.5cm away from the incisal edge. The needle is inserted vertically, and the needle insertion depth is about 0.5cm. Then when it is in the incisal edge, it is also passed perpendicularly to the incisal edge, and then the needle is withdrawn 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 knot is 1cm, and then the length of the thread left when trimming is 1cm.

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

Moreover, when sewing, the sewing level is also something that needs to be paid attention to.

This comes back to anatomy. The anatomy of skin is actually divided into three components: epidermis, dermis, and subcutaneous tissue.

Among them, capillaries mostly run in the subcutaneous tissue, so when suturing, this depth must be mastered.

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

The suturing depth just reaches the subcutaneous fascia, which can lock the damage to the small blood vessels of the incision and achieve a hemostatic effect. There is no need to worry that the large blood vessels, let alone the dorsal digital arteries and veins, will be sutured, affecting the blood supply near the wound.

…

After suturing, Wu Xie said: "Honey, please let go of your hand first and see if there is any more bleeding?"

Wu Xie looked at the work he had stitched and felt that the quality of the stitching this time was far superior to any before.

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

Moreover, Wu Xie also evaluates whether the blood supply to the distal end is normal. If the radial artery or dorsal digital artery is sutured, the distal end will be ischemic and turn black.

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

But obviously, none of this exists. You can control the depth of the suture and know where the layers of your suture are without panicking. This is the confidence brought by knowledge.

It seems like just one glance, but I already understand everything in my heart.

"That's it, nanny, the stitches are done. After you go back, don't touch the water. Come back in two or three days to change the dressing. I'll prescribe you some oral medicine later, and you can go back with a 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 man in his fifties wearing a white coat rushed in.

"Director Lu!" He had just entered. Xu Huifang, who had a very good relationship with Wu Xie, quickly cut her off.

Stand up and meet him, stretch out your hand and show it to him.

"Look at my wound, have you taken care of it?"

Wu Xie didn't say much, but raised his hands in a sterile posture.

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

After carefully examining Xu Huifang's sutured wounds, his eyes flashed slightly!

This wound is extremely beautifully aligned. The needle entry and exit points of the suture look like they were made by two types of staplers. The alignment of the epidermis is also neat and uniform, with no unevenness.

There was no bleeding and no redundant skin pimples.

The level of stitching is okay.

Lu Junyin glanced at Wu Xie and explained with a smile: "Brother and sister, why are you worried about this?"

"We have watched Little Crab grow up, you don't know how reliable he is. He will take care of it for you, why don't you trust him?"

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

Xu Huifang's family owns a noodle shop, which is opposite the town health center. The two of them are very familiar with each other.

"Director Lu, how could I mean such a thing?" Xu Huifang was serious and her tone was serious, for fear that Wu Xie would misunderstand.

As fellow villagers, she and Xiang Mei are also very familiar with each other. If this misunderstanding occurs to Xiang Mei, it will probably be difficult to get along with her as friends again in the future.

After Lu Junyin finished reading, he turned around and left the operating room.

Wu Xie continued to bandage Xu Huifang and explained to her the following precautions, such as details such as whether it would hurt at night after returning.

At the nurse's station, Xu Rong saw Lu Junyin coming out and asked nervously: "Director Lu, is there nothing 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, they will become rumors!" Lu Junyin did not express his position directly, but the warning in his words was still obvious.

Xu Rong was slightly shocked when she heard this, wondering what the director meant by this.

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

But was Wu Xie on duty last time?

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

What's more, Xu Rong went out of his way to find out whether Wu Xie was the one who was fired from the county hospital and sent to the town?

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

…

"Ma'am, your kitchen knife is not very clean. After the sutures are done, you need to take some anti-inflammatory medicine. You don't need to be hospitalized after the surgery." Wu Xie gave Xu Huifang this advice after explaining the postoperative precautions.

When using a kitchen knife to chop meat, the chance of infection is high except for the possibility of tetanus.

"This is about getting some anti-inflammatory shots, that's what I thought too." Xu Huifang nodded, fearing that the wound would become infected.

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