"What did you say?" Chang Yue asked in surprise.

"Uh..." Lao He scratched his head. He knew that Chang Yue would not go to the surgery and was only responsible for writing medical records. "As for appendicitis surgery, the epidural catheter broke during continuous epidural anesthesia, it is said that it should be left in it about 6cm more."

Zheng Ren was about to speak when a "ding dong~" suddenly sounded in his ear.

This sound has been a long time since I won the Nobel Prize, Big Pig's Hoof has not issued any more tasks. Zheng Ren can only rely on the [Best Surgeon] to obtain insignificant skill points and experience values ​​through the continuous task.

[Urgent task: pick one in a thousand.

Task content: Remove 1 epidural fracture catheter.

Task reward: In the calculation of system data, different rewards can be obtained by taking it out differently.

Mission time: 24 hours.]

Zheng Ren is really a little slandering about the big pig's hooves. The task reward is still being calculated and the task is issued? This is too unrigorous.

And the focus is on taking out these six words in different ways.

Originally, Zheng Ren's first idea was to remove the broken epidural catheter surgically, but after seeing these 6 words, Zheng Ren hesitated for a moment. Since the big pig's hooves gave a prompt, it is not feasible to try the interventional surgery method.

Zheng Ren entered the system operating room without hesitation and clicked on the purchase of surgical training. The system operating room rose from the ground and he stepped in. To be honest, Zheng Ren was also a little interested in anesthesia accident. After experiencing such a thing, he would not have been numb if he encountered it.

"Can the anesthesia catheter be broken? Can it be broken? Is it paper?" Chang Yue was particularly surprised.

Not only ordinary people, but for an internal physician, it is unimaginable that the catheter of epidural anesthesia will break.

What exactly is it? Why is it so unsolid? It's simply too magical.

"Xiao Chang, this catheter breakage is not particularly rare..." Lao He hesitated for a moment, and finally told the truth: "According to domestic statistics, the incidence rate is 0.06% to 0.2%, and the incidence rate abroad is 0.0017% to 0.04%.

"Why is it so much worse?" Chang Yue asked in surprise.

"Look at your inexplicable appearance." Su Yun said contemptly, as if he had forgotten that he had just drunk the fragment and was carried home. "Different materials and different ways of avoiding some positions during anesthesia will cause similar things."

"Well, the example I encountered recently was something I heard from someone else. The trainees were excising the tube. If the strength was not correct, the catheter was broken inside." Lao He said seriously: "If you look closely, there are many possibilities."

As he said that, he put down his phone and began to beat his fingers.

"The causes of epidural catheter rupture in surgical anesthesia are complex, and most of them are related to the operation of anesthesiologists, pathological or physiological changes in the puncture area and catheter factors."

"For example, the main reason for the catheter breaking during the pipe is that the catheter is placed too deep. Generally speaking, if it is greater than 5 cm, it may cause breakage."

As he said that, he pressed the thumb of his left hand with his right hand, indicating that this was the first possibility.

"There is also that when the tube is installed, the anesthesiologist is a little panicked, exerting too much force, retracting the tube, and adjusting it. However, during the operation, the tuohy needle did not move, resulting in distortion of the angle and the catheter breaking."

As he said that, he pressed his second finger down again.

Su Yun suddenly said, "Brother Yang, I know why the boss and I have been praising you all the time."

Professor Yang is so dark that he can really connect everything with himself. Speaking of which, he opened Wushuang directly that day, and it seems that he opened the right one... I hope he can open Wushuang anytime and anywhere in the future.

"Well, Professor Yang's approach that day was right. Whether it was surgery or anesthesia, it was really not suitable for violence." Lao He said, "There is that the tuohy needle is inappropriate in the epidural space, and the catheter is located between the needle tip and the bone surface or stuck in the intervertebral joint or bone suture. This requires a lot of anesthesia experience and is also a place where mistakes are more likely to be made."

The third finger pressed down.

"The reason for the catheter breakage during the extubation is related to excessive force when the extubation encounters resistance and repeated attempts to pull out the catheter that has been tied or is wound around the surrounding tissue, etc."

"In addition, the patient has pathological pathology such as spinal stenosis, osteogenesis, pregnancy, epidural space connective tissue hyperplasia, and body position changes. Physiological factors are also important reasons for the breakage during the insertion or extraction of the epidural catheter."

"Consumables also have something to do," Zheng Ren said suddenly.

"Absolutely, the probability of occurrence in China is much higher than that in foreign countries. The reason for the quality of consumables is one point." Su Yun said.

"The material and model of the epidural catheter... I remember that there are literature reports that nylon or polyurethane catheters are stronger than Teflon or polyethylene catheters, while the 19g catheter tends to break at a fixed position near the tip." After Zheng Ren said that, he wiped his mouth and looked at Lao He.

Lao He immediately became serious.

Boss Zheng’s meaning is very clear, but Lao He thinks he can’t guess, so it’s better to listen to Boss Zheng’s opinions.

"Old He, what does that mean?" Zheng Ren asked.

"I read the WeChat message. The person who happened to the accident was the director of the anesthesiology department of a city and county. According to the content, it should be sent in a mass manner." Lao He said, "There was no greetings, nor the thanks for the end. I guess that side was already confused and I don't know what to do."

With just one sentence or one question, Lao He could see a lot of things.

"What does he mean?" Zheng Ren asked.

"Boss Zheng, please read WeChat." Lao He held his cell phone, bent over and ran to Zheng Ren.

[Have you ever encountered the rupture of the epidural catheter? Besides conservatism, what other solutions are there?]

It's a very simple message, the person who sent the message was really confused, and he didn't even have the most basic thanks.

It looks a bit vulgar, but many people are confused when encountering unexpected situations. It is like the first time I went to the province and encountered Wang Hai doing cerebrovascular angiography to push the catheter into it.

At that time, Dr. Wang seemed to be stupid. Liu Zewei and Gao Shaojie took turns to get the guide wire. After the failure, he didn't say anything. He took out the guide wire himself, and he held his hand, not knowing what to say.

So Zheng Ren understood and could guess what the person sending the message meant.

"Old He, ask him if he needs to help him." Zheng Ren said, "By the way, let's clarify where the person is."

"Okay." Old He responded without hesitation.

Although it was a job of wiping your butt, Lao He still didn't have any complaints and took the time to contact him.
