Chapter 2681 Different Ways, Different Rewards

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

"Uh..." Lao He scratched his head. He knew that Chang Yue was not going to be operated on and was only in charge of writing medical records. "For appendicitis surgery, the epidural catheter was broken during continuous epidural anesthesia. It is said that it should be left in about 6cm. a bit more."

Just as Zheng Ren was about to speak, a "ding dong~" sound came from his ear.

This voice has not been heard for a long time. Ever since he won the Nobel Prize, Big Pig Trotter has not issued any more missions. Zheng Ren can only rely on the continuous mission of "Best Surgeon" to get negligible skill points and experience points.

[Urgent task: pick one out of ten thousand.

Task content: Take out one broken epidural catheter.

Task rewards: In system data calculation, different rewards can be obtained by withdrawing in different ways.

Task time: 24 hours. 】

Zheng Ren is really a bit of a big pig's hoof, the mission reward is still being calculated and the mission is announced? This is too imprecise.

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

Originally, Zheng Ren's first thought was to surgically remove the broken epidural catheter, but after seeing these six characters, Zheng Ren hesitated for a moment. Since Big Pig's Trotter gave a hint, it is not infeasible to try interventional surgery.

Zheng Ren entered the system operating room without hesitation, and clicked to buy surgical training. The system operating room rose from the ground, and he strode into it. To be honest, Zheng Ren is also a little interested in anesthesia accidents. After experiencing such things, if he encounters them, he won't be numb.

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

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

What the hell is it, why is it so weak! It's just so magical.

"Xiao Chang, the rupture of the catheter is not particularly rare..." Lao He hesitated, and finally said 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 there so much difference?" Chang Yue asked in surprise.

"Look at your ignorance." Su Yun said contemptuously, as if he had forgotten that he just drank the fragments and was carried home not long ago, "Different materials and different ways of avoiding certain positions during anesthesia will cause similar things. "

"Well, I recently encountered a case that I heard from others. A trainee extubated the tube, but he didn't use the right force, and the tube broke inside." Lao He said with some seriousness: "If you look carefully, there are many possibilities. .”

With that said, he put down his phone and began to snap his fingers.

"The causes of epidural catheter breakage during surgical anesthesia are complex, most of which are related to the anesthesiologist's operation, pathological or physiological changes in the puncture area, and catheter factors."

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

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

"What's more, when encountering resistance when inserting the catheter, the anesthesiologist panicked and used excessive force to withdraw and adjust the catheter. However, the Tuohy needle did not move in coordination during the operation, which caused the angle to be twisted and the catheter to break."

Saying that, the second finger pressed down again.

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

Professor Yang has black lines all over his head, and he can connect himself with everything. Speaking of which, I opened Wushuang directly that day, which seems to be the right way... I hope I can open Wushuang anytime, anywhere in the future.

"Well, what Professor Yang did was right that day, whether it is surgery or anesthesia, it is really not suitable to use violence." Lao He said, "The other thing is that the Tuohy needle is not properly positioned in the epidural space, and the catheter is located between the needle tip and the bone surface. Occasionally, it is related to intervertebral joints or bone sutures. This requires a lot of experience in anesthesia, and it is relatively easy to make mistakes."

The third finger pressed down.

"The reason for catheter breakage during extubation is related to excessive force when extubation meets resistance and repeated attempts to pull out a catheter that has been knotted or entangled with surrounding tissues."

"In addition, the patient's own pathological and physiological factors such as spinal stenosis, bone hyperplasia, pregnancy, hyperplasia of connective tissue in the epidural space, and changes in body position are also important factors for the rupture of the epidural catheter during insertion or extraction. reason."

"Consumables are also related." Zheng Ren said suddenly.

"Are you sure? The probability of occurrence in China is much higher than that in foreign countries. The reason is the quality of consumables." Su Yun said.

"The material and model of the epidural catheter... I remember that there are reports in the literature that nylon or polyurethane catheters are stronger than Teflon or polyethylene catheters, and 19G catheters tend to break at a fixed position near the tip." Zheng Ren finished, Wiping his mouth, he looked at Lao He.

Lao He immediately became serious.

Boss Zheng's meaning is very clear, but Lao He feels that he can't guess, it's better to listen to Boss Zheng's opinion.

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

"I read the information on WeChat. The person who had the accident was the director of the anesthesiology department of a city or county below. Judging from the content, it should be a group post." Lao He said, "There is no greeting, and there is no thank you at the end. I guess that side is already confused. I don't know what to do with it."

With just one sentence and one question, Lao He could see many things.

"What does he mean?" Zheng Ren asked.

"Boss Zheng, please check WeChat." Lao He held his mobile phone, bent over and trotted to Zheng Ren's side.

[Excuse me, have you ever encountered the rupture of the epidural catheter? Besides being conservative, is there any solution? 】

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

It looks a bit vulgar, but many people are confused when encountering unexpected situations. It was like going to the province for the first time and encountering the situation where Wang Hai had a cerebral angiography and pushed the catheter in.

At that time, Dr. Wang seemed to be completely stupid. Liu Zewei and Gao Shaojie took turns to get the guide wire, but he didn't say a word when they failed. He took out the guide wire by himself, but he held his hand and didn't know what to say.

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

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

"Okay." Lao He agreed without hesitation.

Although it was a butt-cleaning job, Lao He still didn't complain at all, so he took the time to get in touch.

"Boss, you really do all kinds of work." Su Yun had already guessed that his boss would have itchy hands, but when he said that sentence, he still couldn't help but slander in his heart, and directly sprayed out.
