Chapter 1378 Who is Afan

"Nitrete poisoning? The color of blood draw? What color is that?" Shen Lang pondered.

"At that time, this patient was considering carbon monoxide poisoning, but his condition did not improve during the treatment. At this time, another doctor accidentally saw the urine routine for admission and found that two plus numbers of nitrite were found."

"What is that?" Shen Lang tried hard to recall his urine routine.

Regular urine is one of the four routine tests for admission, but it mainly depends on whether there are red and white blood cells, urine sugar, and whether the patient has urinary tract infections, urinary stones and diabetes.

No matter how many of them are ketone bodies, Shen Lang forgot that the regular urine also has nitrite.

"A reward for routine urine," Zhou Congwen said, "I found that the concentration of routine urine nitrite increased, and the high-hemoglobin concentration was urgently checked, and the return was 32%.

Shen Lang was a little confused, Xiao Kai frowned, "Professor Zhou, it should be obvious when you draw blood."

"What does it mean, Dean Xiao." Shen Lang asked.

"The arterial blood of patients with nitrite poisoning is typical chocolate brown, and does not change color when exposed to air. Combined with the results of routine nitrite positive urine and the methhemoglobin concentration measurement, and referring to the characteristics that are much different between SpO2 and SaO2, the diagnosis can be determined."

Xiao Kai is worthy of being an old clinical clinic and is very clear about it.

Zhou Congwen looked at Shen Lang with a smile, "How about it, you said you are gossiping randomly, you are not convinced, I will reply this time."

After saying that, he looked at Xiao Kai and smiled, "Indeed, the patient was nitrite poisoning. The doctor in the emergency department thought it was carbon monoxide poisoning, so he almost misdiagnosed. Fortunately, he had a urine routine."

"What's the matter?" Shen Lang was still dissatisfied.

In Shen Lang's view, nitrite poisoning is less than once in eight hundred years.

"I'll tell you the key points of this matter." Zhou Congwen returned to the ward and took Shen Lang back to his office. He opened the window and found Bai Lingzhi.

"In the past, nitrite poisoning was common, but now it's not many."

"Why?"

"Because nitrate looks similar to table salt and white sugar, it is easy to be used as table salt in the northern region, and it also occurs frequently in the southern region. According to literature statistics, poisoning is the first in my country because of mistaken nitrite consumption."

"Director Xiao knew about this. It is probably because many children were naughty many years ago and mistakenly took nitrite as sugar and ate it wrong."

Xiao Kai nodded.

"This is in the past, and nitrites are rare on the market now, and it is unlikely that you will eat the wrong one.

Nowadays, most of them are used in food processing.

During food processing, nitrates are often used as the colorant for meat and fish, so that the pickled products are flesh-red, but if excessive amounts are added and reduced to nitrite, poisoning can be caused."

"Which boss is confused and put a handful of nitrite when making cured meat, then you'll be fucked."

"Collective poisoning!" Shen Lang's eyes were shiny and his ears were erected.

"Yes." Zhou Congwen said, "Everyone thinks it is ordinary food poisoning. At this time, you stand up and shout that there is only one truth!"

Shen Lang's eyes were brighter, like a stone thrown into a small pond, rippling ripples.

Zhou Congwen could vaguely feel that Shen Lang had already put himself in. This situation was indeed a big scene of pretending.

"The lethal amount of nitrite is about 3 g. The incubation period of poisoning is short. Generally, it can start from 0.5 to 3.0 hours after eating. The shorter ones can start from 10 to 15 minutes.

In addition, 0.2 to 0.5 g of nitrate can cause symptoms of poisoning."

"Ordinary patients have blood discoloration, just like Dean Xiao said. If they meet severe patients, their whole body will look blue."

"Blue?!" Shen Lang was surprised.

"Yes." Zhou Congwen nodded, "Nitrete absorbs blood very quickly, which can oxidize Fe2+ in normal hemoglobin to lose its oxygen-carrying capacity, forming methorhemoglobinemia and causing hypoxia in the body's tissues."

"The body turned blue, like Afan..." Zhou Congwen said, suddenly stopped.

He originally wanted to say Avatar, but now it is 2003, and Avatar should not have been released. He almost said that. If Shen Lang has a good memory, how would he explain it when the movie really comes out?

It was so annoying, Zhou Congwen was a little upset.

"Who is Afan? Your girlfriend? No, your girlfriend is the landlord's daughter named Liu Xiaobie. Afan is your ex-girlfriend?" Shen Lang keenly realized that something was wrong and asked.

"roll!"

"Don't go." Shen Lang said with a cigarette in his mouth and smiled.

Seeing Shen Lang deliberately making fun of him, Zhou Congwen became evil and brave.

He looked at Shen Lang very seriously, "As a clinician, I don't mean that I can't gossip, but that I need to know what the gossip means in detail."

Shen Lang was stunned. He looked at Zhou Congwen, wondering what was wrong with this guy, so how did he start Huang Lao's preaching mode.

But he knew the tactfulness and knew that he could no longer interrupt Zhou Congwen's preaching at this time.

Once this mode is turned on, both Mr. Huang and Zhou Congwen are terrible. They are focused and serious, thinking that what they do is the most correct thing in the world.

The devil is obstructed, it is really an impediment. Shen Lang sighed deeply in his heart.

"For example, all kinds of gossip..."

Zhou Congwen was no worse than Huang Lao's nagging, especially when he was facing Shen Lang's possible secret, he tried hard to muddle the water.

After talking for 20 minutes, Xiao Kai was so silent that he was speechless.

Professor Zhou Congwen and Zhou said these words very well. I guess if he wants to participate in the weekly meeting of the hospital, he can be unwritten for an hour and keep everyone from talking about it.

It would be a pity not to be the dean of this quality, Xiao Kai thought to himself.

"Remember?" Zhou Congwen said dryly, and finally looked at Shen Lang and asked.

"Congwen, I understand." Shen Lang said with a serious expression, "By the way, I opened my eyes in the emergency department a few days ago."

Xiao Kai smiled on his face when he heard Shen Lang's hob meat.

"What's wrong?" Zhou Congwen asked.

"I'm a very vulgar middle-aged man. I found a friend from the emergency department and said that I have something there."

"Oh? What did you insert?"

"Garlic sprouts." Shen Lang's eyes were flashing. He seemed to have not heard a word of Zhou Congwen's words just now, and began to spread another gossip.

"I'll go!" Zhou Congwen laughed, "Pretending an elephant? Crayon Shin-chan? Garlic sprouts are rare."

"I said so at the time."

Shen Lang was intrigued, and he started gossiping with Zhou Congwen with a smile. As for what Zhou Congwen said before, he seemed to have not heard a single word.

Zhou Congwen didn't care what Shen Lang was talking about, as long as he didn't chase him and asked who Afan.

Xiao Kai felt a little strange when he saw the two chatting happily.
