Doctor: It's reasonable to perform surgery on yourself.

There were not many people coming to the emergency department. In addition to Wang Ping, there were also Wang Fan, Yun Mei, etc.

There was even a mobile phone placed on one of the tables, with a big, attentive face inside.

There was a large pile of publications on Wang Fan's table, which was distributed at each seat.

"Take a look. This is a publication published by our emergency department. It's a special issue of Dr. Xu. There are many photos of him during surgery. He's so handsome!"

"There are also details of the surgery taught by Dr. Xu himself!"

"This thing is circulated internally, and we usually keep it privately. But after this incident, all departments are one family, so we reluctantly gave up and shared this publication. We don't want more, the cost is Thirty yuan!”

After these words, many people really bought it.

Especially for female doctors, when they saw the handsome photo of Xu Qiu on the cover of the magazine, their eyes immediately lit up and they paid and purchased in one go.

The doctors at the brain surgery department were confused.

Internal circulation?

Isn't this thing just on the nurse's desk in the emergency department, and anyone can buy it?

Several people looked at each other, with only one thought in their hearts: Wang Fan would really be underestimating his talents by becoming a doctor instead of doing sales...

…

Xu Qiu withdrew his gaze.

He did not expect that Wang Fan would treat this meeting as a sales fair.

Moreover, the effect was surprisingly good, and one hundred copies of the publication were sold out in one minute.

Those who didn't grab it looked frustrated and told them to leave a copy for them later.

"Wang Fan, what are you talking about? Sit down quickly. Dr. Xu is about to start his lecture." Wang Ping saw that Wang Fan had sold out and called him back at the right time.

"Okay, hehe..."

Wang Fan quickly sat down and looked at Xu Qiu expectantly.

The lecture also officially started.

"Gas gangrene is a severe myonecrosis caused by the invasion of wounds by Clostridium bacteria. The bacteria are very pathogenic and 15% can invade the blood and cause sepsis. The incubation period of gas gangrene is 1 to 4 days , mostly three days after the injury..."

"There is a history of trauma. First consider tetanus and gas gangrene. The identification is very simple. You must do a physical examination. If there is crepitus on palpation, it will be diagnosed as open lower limbs based on screening tests, X-ray examination, wound secretions, and anaerobic bacterial culture. Gas gangrene caused by sexual fracture..."

"If there is no history of trauma, necrotizing fasciitis caused by invasive streptococci and Staphylococcus aureus should be highly suspected. It may be complicated by mixed infections of enterococci in the later stages... The indications for medication for this disease are different. First, consider cefotaxime. and ornidazole.”

"..."

Xu Qiu's lecture was not interesting, it could even be said to be boring.

There is not a word of nonsense, every word can withstand scrutiny, concise and concise, like a rigorous thesis.

This style is very popular among senior directors like Wang Ping.

They have experienced countless patients. When Xu Qiu teaches, they will recall the patients they have treated before, and then suddenly realize that this is what they should do. According to Xu Qiu's diagnostic ideas, they can avoid many detours.

After more than an hour of lecture, everyone benefited a lot.

After returning to their respective departments, many people were still a little dazed.

This lecture was too valuable - was it really completed by a twenty-four-year-old resident doctor without any preparation and without any preparation?

…

In the emergency department, Xu Qiu continued to be busy after finishing his lecture.

In the afternoon, a patient with burnt hands was brought.

"What happened?" Xu Qiu asked.

The patient said with some humiliation: "I went to a convenience store to buy something, and the boss didn't give me change and asked me to buy something.

I was not happy and saw a goose being stewed in an iron pot set up in front of his shop. I didn’t want any money, so I ran away with the iron pot in my arms.

As a result, I forgot that the iron pot was hot..."

Xu Qiu was silent.

He turned to look at the injury.

There are a large number of blisters of different sizes on the patient's palm. The wound surface is red and moist, and the redness and swelling are obvious.

Pain is also very sensitive.

Xu Qiu made a judgment immediately.

The damage has at least reached the germinal layer, and may even have damaged the dermis and papillary layers. It is a superficial second-degree burn.

This kind of injury looks scary, but it can heal in a week or two, and there will be almost no scars after recovery, only slight pigmentation.

On the contrary, it is small blisters or no pain at all that are really scary.

Small blisters may seem minor, but they have actually damaged more than the dermal layer and will leave scars after recovery.

As for the complete lack of pain - that is the most severe third-degree burn. The nerves and blood vessels are all damaged, and there is no ability to recover independently, so skin grafting can only be done.

"Let's do a simple process." Xu Qiu said.

Superficial second-degree burns are easy to treat.

"One to one thousand benzalkonium bromide."

Intern Chen Qiao immediately prepared the medicinal solution and then cleaned the wound.

Then, Xu Qiu took out a sterilized empty needle, inserted it into the blister, and drained out the liquid inside.

"After bandaging, be careful not to touch the water. I'll prescribe some burn medicine for you. You go back and apply it..." Xu Qiu gave the doctor's orders.

After sending away the goose thief, almost half an hour later, another patient came with his hands wrapped in gauze.

Through the mask, Xu Qiu could smell the rich aroma of stewed goose emanating from her hands.

Xu Qiu frowned and said, "Why are you here half an hour late?"

"Hey, doctor, you are really amazing!"

The patient's expression was painful, but his eyes suddenly lit up and he was very surprised.

After he sat down, he spread out his red and white hands and sipped his saliva and said: "Doctor, half an hour ago a bastard stole the stewed goose in front of my house. As a result, the fool hugged the red-hot goose. The iron pot just wanted to run away, it made me laugh so hard, hahahahaha!”

Xu Qiu: "Then how did you get injured?"

"I want to move the iron pot back..."

Xu Qiu was silent.

Crouching dragon and phoenix chick.

Beside him, Chen Qiao covered his mouth and thought about all the sad things he had encountered in his life. In the end, he couldn't help pouting his mouth, like a duck.

Xu Qiu is very calm here.

This man's hands exuded the aroma of stewed goose. His hands were covered with small blisters and his pain was relatively dull. The wounds were no longer red and swollen, but the edema was obvious.

Worse than the previous one, it was a deep second degree burn.

The treatment methods are much the same.

However, there is no need to remove the blisters for superficial second-degree burns, as long as the fluid is drained.

Now this person has to remove the blister skin.

and,

Judging from the smell on his hands, the patient not only grabbed the iron pot, but may have also spilled the stewed goose juice all over his hands.

Therefore, additional foreign body removal, debridement, etc. are required.

In addition, the packaging of the wound is quite different from the previous superficial second-degree burn.

The inner layer is made of oily gauze with an appropriate amount of antibiotics added.

The outer layer is covered with absorbent dressing and wrapped repeatedly until a white gauze bag of about five centimeters is wrapped.
