Thousands of miles away, as long as you are Chinese, you are a fellow countryman!

"I'll go down and see, and you'll stay up there." Zhou Qiao said.

Seeing the two white twin little sisters with a worried face, Zhou Qiao couldn't help but laugh and said, "It's okay, it should be the Chinese in Chinatown." ”

The other party slapped the door in a hurry, Zhou Qiao hurriedly took three steps and made two steps, came to the first floor, and opened the door!

Outside were five people, three Chinese, two foreigners, and the injured one was a relatively strong black man, unusually muscular like a curly-haired baboon.

The right hand was wrapped in a towel, and the whole towel was red and full of blood!

"Brother Jianjun, what's going on?" Zhou Qiao knew one of the Chinese, so he hurriedly asked.

The other party is in his forties, a veteran, who has been in the United States for seven or eight years, his name is Zhang Jianjun, and he is the lobby manager of the Chinese restaurant "Tang Yunxuan" in Chinatown. The boss inside is related to him.

At that time, Zhou Qiao's aunt handled the funeral, and Zhang Jianjun followed Tang Yunxuan's boss, as well as President Zhang of the Martial Arts Association and several other Chinese, to come over to help.

The thank-you banquet after the funeral was completed was also held in Tang Yunxuan, and the injured black man seemed to be a cook helper inside. I usually do chores such as chopping vegetables, washing dishes, and carrying heavy objects.

President Zhang and these people are very enthusiastic and help with the operation before and after, and Zhou Qiao is still very grateful.

It's just that at the banquet, he vaguely heard people say that Chairman Zhang and others have ties with Chinese gangs such as Hongmen and Huaqing Gang, so he usually walks around with them less.

After all, Zhou Qiao has lived in the peaceful and prosperous era of China all the year round, and although he is a medical student, although he yearns for the gangsters, he actually has a respectful mentality.

He is a medical student, close to others, and when the time comes, there will be enemies looking for revenge or something, and he won't know if he is hacked to death!

The main thing is still timidity. When you see gangsters on the street, you only dare to call 110, and you don't dare to come forward to see the righteous and brave kind!

On the other hand, it is a weak scholar with weak physical strength!

Because of the lack of physical strength, I don't have the courage to go up and do it with people.

"Xiao Zhou, you can stitch it, right? Jack Bu accidentally injured his hand while chopping vegetables, and the wound was large and needed urgent treatment! Zhang Jianjun said.

Jack Bu was the black man.

Hearing that it was injured by cutting vegetables, not a gang fight, Zhou Qiao immediately relieved his heart and hurriedly invited the group into the clinic.

When he came to the disposal room, Zhou Qiao asked the tall black man to sit down, and the rest of the people were a little farther away, so as not to hinder his work.

Then, Zhou Qiao gently unwrapped the towel wrapped around the black brother's hand.

The blood flowed and dripped down, and the blood still hadn't stopped, probably hurting the arteries, and the black brother grinned in pain.

In the palm of the human hand, there are radial and ulnar arteries, which converge at the superficial arch of the palm.

Most likely, it also hurt a lot of nerves.

This injury is not simply a matter of skin and muscle stitching.

Vascular sutures and nerve connections are required.

Zhou Qiao glanced up at this person, and said in his heart that he was really a good man, he was so seriously injured and lost so much blood, he could still bear it!

If this had been an ordinary person, it would have been in shock a long time ago!

"Joe, I'll help you!"

Elena and Ava were not worried about Zhou Qiao alone after all, so they walked in together in a crowd.

"Hmm." Zhou Qiao nodded and instructed Elena, "0.9 sodium chloride mixed with complexed iodine, in addition, 2% lidocaine 5mL!"

After thinking about it, he said, "10mL!"

Mainly, this black brother is too big, estimated to be 300 pounds, and he is as strong as a cow!

Elena was quick with her hands and feet, and immediately handed the things that Zhou Qiao needed to his hands, and even, the anesthetic had been inhaled into the needle, she pointed the needle towards herself, and handed the end of the needle to Zhou Qiao.

It's just that Elena glanced at Zhou Qiao with a worried look.

Ava was also on the side to help, and the two looked at each other, both of them quite apprehensive.

Mainly, Zhou Qiao's face was very nervous, and he looked like a novice!

It is completely different from the smooth flow of appendectomy surgery before, and the lifting of weights is light!

There are also sutures in appendix surgery, but they are relatively simple, mainly suturing the peritoneum, subcutaneous fat, and epidermis. At that time, Zhou Qiao used the continuous stitching method.

However, appendicitis surgery is a relatively low-level operation, although it will break through the peritoneum, there is no major blood vessel around the appendix, at most the capillaries are cut off, and only effective ligation is required to stop the bleeding.

Having appendix surgery and injuring the aortic blood vessels is called medical malpractice! Experienced doctors don't make this mistake!

Therefore, although he has a master appendectomy, this skill focuses on the appendix itself, how to find, how to identify, how to remove, how to prevent and treat subsequent complications...... I don't know much about suturing!

To put it simply, the same sutures used in appendix surgery do not apply to the current suturing of huge wounds on the palms of black brothers!

"Joe, isn't he?" Both Elena and Ava couldn't help but have this idea.

Zhou Qiao was indeed a little nervous, he was a medical student who had just graduated, and he had not been trained for a long time, and it was the first time he had seen such a serious injury! The only appendectomy that is good at this time is not needed!

The black man's entire palm, running from left to right, has a deep and long opening, which is shocking, and even when Zhou Qiao is injecting lidocaine, his hand is trembling slightly.

Usually, lidocaine leaves the factory at a concentration of 2%, and clinically according to the patient's condition, it can be formulated into a solution of different concentrations for application.

For example, depending on the nerve block, the formulation varies from 0.5%, 0.8%, 1%, 1.5%, and 2%.

The higher the concentration, the longer, deeper, and stronger the blockade, and the greater the impact on the circulatory system.

With low concentrations, the duration of the block will be shorter and the onset of action will be slower. The concentration is lower for the elderly and children, and higher for young adults.

Conventional packaging is available in 5ml, 10ml, and 20ml, and the maximum dose for each patient at one time does not exceed 500mg.

However, to be on the safe side, it is generally accepted that the safety standard for adults is 300mg.

Zhou Qiao didn't dare to fight more, if he fought too much, something would happen, but he would never dare to fight less!

Playing less, it doesn't work well for this black brother!

The other party is not Guan Erye, and he can endure the light wind and lightness. Before it started, the other party screamed in pain and almost jumped!

At the beginning, he wanted to rely on his own strength to do it once, at least when he was debrided, but when he injected local infiltration anesthetic, he was so nervous.

Because, Zhou Qiao suddenly remembered, there are so many nerves on the palm, if one accidentally hurts the nerves, what should it be?

In the future, there may be bugs in the function of other people's hands?

This is medical malpractice!

Zhou Qiao pushed very slowly, his hands were still trembling slightly, not only Elena and Ava noticed it, but even the people who were standing behind Tang Yunxuan who were watching from the side also noticed it.
