Chapter 1213

Li Yifan nodded quietly. He was still investigating, but there was no result for the time being.

He can't tell what this bad smell is for the time being. He has always been very sensitive to the smell. As a traditional Chinese medicine, seeing, smelling and asking is the basic skill. It's necessary to keep a good sense of smell, especially when he often sniffs the smell of medicinal materials through his nose, so his sense of smell has always been very good.

He also smelled a lot of rotten odors, but it was the first time for him to smell such strange odors.

"Keep this clue first." Li Yifan thought that this might be a breakthrough, but there was no result for the time being, so he turned to other directions to think. He observed the patient's body. "His skin ulceration speed is so fast. Generally speaking, skin redness, swelling and red spots are due to the action of real bacteria. Occasionally ulceration will only occur in a very small range, which is due to fungal infection More. Is it possible that such a large-scale ulceration is caused by fungi? "

As soon as the speculation was put forward, he rejected it himself.

Although fungal infection does lead to skin ulceration, the speed of ulceration is very slow, and it is easy to cure. As long as you rub some fungicides such as daphnetin, with the self-healing ability of the skin, you will soon get better.

After thinking about it, he asked, "have you considered skin infection?"

Solie immediately nodded and replied, "yes, at the beginning, our research direction was fungal infection, but after thinking about it, the possibility is too small. So after careful discussion, we thought it was some kind of bacteria, and then we collected a little skin tissue for testing, and found that there were no suspicious bacteria, only some common bacteria that would adhere to the surface of the skin. "

"It's not a virus? That is to say, from the direction of skin infection, there should be no result? " Li Yifan frowned.

"Well, it should be. However, some of the doctors I invited insisted on studying from this aspect. After all, if there is a possibility that we don't know, it will lead to negligence if we don't study, "Solie replied.

Li Yifan looked back and observed the patient again.

Skin infection, that is, the possibility of bacterial infection has been eliminated, so why is the patient's skin ulceration so fast?

Blood?

Li Yifan immediately thought of a possibility, "can it be blood?"

"Blood?" Solie was stunned for a moment. "You said this possibility, we have speculated that, indeed, the internal blood of the human body is all over the body, and has been flowing, and the skin contains a lot of blood and body fluids. If there is a problem with the blood, it will be exposed on the surface of the skin, so we also collected his blood for testing, and found that his blood does not contain suspicious substances. "

"Not even blood?" Li Yifan was stunned.

"It's a pity, no!" Solie sighed.

Li Yifan twisted his brows and continued to think.

As a natural doctor, Solie's medical skills are very excellent. The doctors he can invite will certainly have good medical skills.

That is to say, they must have thought of the common possibility of cable tension for a long time.

They can't diagnose the disease, there is only one possibility, that is, the patient's disease is beyond the scope of their medical skills.

What's the possibility?

Li Yifan closed his eyes and began to imagine various possibilities in his mind.

Neurotoxin?

Impossible. Although neurology is a relatively advanced branch of modern medicine, and there are not many people who can master it, it is often seen, and the possibility is too low.

Organ canceration?

It's impossible. Although Li Yifan has just planned to speculate on the possibility of organ canceration from the perspective of organ failure, he can indirectly deduce why patients emit a strange odor, which may be caused by organ failure.

But he felt that he could think of all the possibilities. There was no reason why they couldn't think of them.

Is there something in the blood that can't be detected by modern instruments?

It's too unlikely.

Although Li Yifan has studied medicine for such a long time, he has encountered some problems that can't be detected by modern instruments, such as Qi Wei's paralysis, but the instrument didn't detect the insects hidden in Qi Wei's spine.

But that kind of probability is too small, and he can't think of any kind of material that can make people fester all over the body. In just ten days, a person's organs will fail and produce symptoms similar to cancer.

After thinking for a long time, Li Yifan suddenly flashed a word in his mind: poison.

Poison

Poison?!

Li Yifan trembled all over, and suddenly thought of a possibility. Yes, poison, ulceration, unknown symptoms and stench. Isn't it like being poisoned?

He suddenly opened his eyes, turned his head and stared at the two people, "Dean Suo, have you ever considered a possibility, that is poison?"

"Poison? You mean the virus? " Solie was stunned.

"No! I'm talking about poison. It's a common saying in traditional Chinese medicine. Poison! " Li Yifan said seriously."Poison?" Solie frowned. "We have thought about the possibility that his symptoms are really like some unknown toxin, but the possibility is too small in my opinion. Our doctors have also discussed it. If it's toxic, then when we check his blood, we should analyze the unknown drug residues. "

Hearing this, Li Yifan smiles, "no! I'm sure it must be poison

"What?" They were stunned.

"Go out first! Speak more clearly outside Li Yifan smiles and turns to leave the ward.

They looked at each other and didn't understand what he meant, but they followed him.

Out of the ward, Solie couldn't wait to ask, "Li Shao, what do you mean? Poison? Obviously, we have tested his blood, and there are no suspicious substances left. We have even tested his flesh and blood, and there are no suspicious substances either. "

Lao Qin was puzzled and muttered: "if it's really poisonous, the instrument can't check it out. It's poisonous. You can test it with a silver needle. "

Silver needle will turn black when encountering toxin, so it is an easy test method.

Hearing this, Li Yifan couldn't help laughing and shaking his head and said, "calm down first and listen to me. In my opinion, your investigation and analysis methods are correct. If you do use the instrument to check, if he is really poisoned, he can find suspicious substances in his blood. But have you ever thought about the possibility that this poison is a gas, which is poisoned immediately after smelling, but the dosage is very small, colorless and tasteless, and the materials used are not detected by modern instruments. In this case, they are unconsciously poisoned. "

They first heard that Li Yifan agreed with them and thought what kind of explanation he could give?

But when they heard the last, they were stunned.

"Colorless and tasteless, the instrument can't detect the toxicity of ingredients? Do you have this poison? " Solie said stupidly.

"I'm sure!" Li Yifan nodded, "it's not convenient for me to say more about some things, but I can tell you responsibly that some things can't be detected by modern instruments. In ancient times, there were colorless and tasteless poisons that were extremely difficult to detect, and I even prepared them myself. "
