Chapter 80

'Under the high altitude environment, atmospheric pressure and oxygen partial pressure gradually decrease, and oxygen supply is hindered, resulting in increased anaerobic metabolism of brain cells, decreased ATP production, dysfunction of brain cell membrane sodium ion pump, intracellular sodium and water retention, causing cytotoxic brain edema. .

If it cannot be rescued in time, it will become a vicious circle of [cerebral hypoxia-cerebral edema-increased intracranial pressure-cerebral circulation disorder-difficulty in diffusing blood oxygen-cerebral hypoxia]. '

Li Ang thought silently.High altitude cerebral edema is more common in people who quickly enter the altitude above 4000 meters. In the early stage, severe headache, vomiting, palpitation, shortness of breath, and unresponsiveness can be turned into coma in severe cases.

Chang'an is about 400-700 meters above sea level, and Taibai Mountain in Qinling is more than [-] meters.But the distance between the two places is two hundred miles, so it is impossible for this tattooed man to climb Taibai Mountain, have a high mountain reaction, and then bring it back with a galloping horse.

If it is not high mountains and plateaus, it should be a low-pressure and low-oxygen environment similar to the conditions of high mountains and plateaus.

For example, artificially created low-pressure chambers, or using flying swords to carry them quickly into the air - this should also induce high-altitude cerebral edema.

However, Pu Liuxuan once mentioned that there is a strong wind above the surface of the earth, and it is ravaging and ravaging all the time.The higher you go, the more dangerous the sky and earth winds are.

Even sturdy armor made of fine steel, thrown into the high wind layer, will be twisted into mud in the blink of an eye.

There was no obvious trauma on the body of the tattooed man, and it should not have been caused by the rapid flight.

Alien?sorcery?Or something else.
Li Ang pondered for a moment, and stopped looking into it - Jiao Cheng and the others remained silent, obviously hiding a secret and unwilling to answer.

"Bring the ice cubes!"

Di Wu brought people and brought ice cubes and wooden buckets.

Not long after, the men who went to Dongshi to buy kelp and plaster also returned.

"Break up big ice cubes, put them in bags, and put them over his body and head."

Li Ang gave orders to have Di Wu and others cover the unconscious man with ice.

This can reduce cerebral blood flow, reduce cerebral metabolic rate, promote the recovery of injured brain cells, and alleviate the vicious circle caused by hypoxia.

'The treatment of high altitude cerebral edema, the first is to lower the altitude, rest in bed, and keep breathing.Then came hypothermia and oxygen.

High-concentration and high-flow oxygen inhalation can correct the hypoxic state of the brain and break the vicious circle. '

Li Ang said silently, 'The problem is that there is no high concentration of oxygen now.

Calcium peroxide, hydrogen peroxide, manganese dioxide, etc. cannot be done in a short time, and the method of electrolysis of water requires continuous and stable power. '

The electric light talisman and the lightning strike technique are both talismans of the cloud patrol realm, and they don't seem to be stable enough. When enough high-concentration oxygen is produced, the daylily will be cold.

'Only the last way is to use drugs to lower intracranial pressure and improve cerebral circulation. '

Li Ang looked at the large amount of kelp bought by Jiao Cheng's men.

The kelp is sun-dried and has a white frosty coating that looks a little like mildew.

'The hoarfrost on the surface of dried kelp is actually mannitol, an isomer of sorbitol.Mannitol tastes like sucrose.It is one of the most commonly used drugs for the rescue of brain diseases. After injection, it can rapidly increase the plasma osmotic pressure, allowing the water in the tissue to enter the blood vessels, thereby reducing the intracranial pressure and intraocular pressure, and relieving cerebral edema. '

The information on mannitol flashed in Li Ang's mind, and Jiao Cheng's subordinates covered the wooden barrel with several layers of washed gauze.
Then wash the kelp with water, scrape off the hoarfrost on it, and pour the water with the hoarfrost into a wooden bucket.

The gauze acts as the first layer of filtration to filter the sand and gravel dirt on the surface of the kelp.
The second step is flocculation.

Li Ang opened the gauze covering the barrel, wrapped it with plaster on a wooden stick, and put the wooden stick into the bucket for stirring.

The best flocculant should be chitosan or carboxymethyl chitosan, and aluminum sulfate, ferric sulfate, etc. can be used, which can adsorb and separate colloids.

Use the plaster for life.

"Almost done."

Li Ang stirred for more than 7 minutes. Seeing that the solution gradually settled and became clear, he stopped stirring.

After a few minutes, the turbidity settled down, and the solution in the bucket was statically stratified.

Li Ang brought the ceramic bottle and filled it with the supernatant.

The standard for the treatment of cerebral edema is intravenous infusion of 20% mannitol.

The solubility of mannitol here may be about 2%-2.5%, which is far from the concentration and hygiene standards of intravenous drip.The quality is not enough, the quantity is enough, and the drink is enough.

Li Ang asked someone to pour the solution in the bottle into the unconscious man's mouth.
At the same time, people continued to change the ice pack on the unconscious man, and then stood by and waited.

After an unknown amount of time, the tattooed man finally opened his eyes and looked to the side weakly, trying to remove the cold ice pack covering him.

Seeing that the other party regained consciousness, the cerebral edema was temporarily relieved.
Li Ang turned to look at Jiao Cheng, and said lightly: "He wakes up and stays on his back for seven days. If his symptoms worsen, he will be fed the filtered kelp infusion solution I just did. Don't drink too much, you will still die if you drink too much. .

Now, it's time to deliver on your promise. "

The comatose man was Jiao Cheng's scum's minion. The sequelae of cerebral edema, recovery after recovery, and diarrhea caused by oral mannitol were completely out of Li Ang's consideration.

Jiao Cheng looked away from the unconscious man and nodded to Li Ang, and the bald Di Wu took Li Ang around and walked out of the room and walked upstairs.

"You also leave."

After Li Ang left, Jiao Cheng waved his hand to the hands in the room, and screened everyone including the two swordsmen.

He walked to the tattooed man's hospital bed, held the other's hand tightly, his eyes flashed with light, and lowered his voice: "Sanlang, tell me, what did you see in the tomb of Sword Immortal under Chang'an Ghost City? ."

----

"Sunrise."

"Go out and talk."

In the upstairs room, Li Ang raised his hand to stop Song Shaoyuan, took him and You Duzhi, walked out of the pavilion under the leadership of Di Wu, and saw Wu Shiqi, who had been staying in the courtyard open space.

"Mr. Li Xiaolang."

When Wu Shiqi saw Li Ang, he immediately stood up from the stone and cupped his hands more respectfully.

He was not surprised that Li Ang was able to leave the pavilion safely, but he was surprised that he was able to walk out with Song Shaoyuan and You Duzhi at the same time—you must know that You Xiao was the cash cow of Lianhualou,

And her attempt to abscond definitely touched Jiao Cheng's inverse scales.

Li Ang was able to leave with the two of them safe and sound
Li Ang didn't care about Wu Shiqi's trance and surprise, and bowed his hands to him, "Brother Wu, thank you this time."

"what--"

Wu Shiqi came back to his senses, and hurriedly bowed his hands to return the salute, and repeatedly said, "Don't dare, I'm just leading the way down."

"Li Xiaolang-kun, we'll clear things up now."

Di Wu looked at Li Ang with flickering eyes, and the implied meaning was very obvious - in the attic today, nothing happened.

"Well, when I send the remaining money, it will be settled."

Li Ang nodded indifferently and walked out of Pingkangfang with the three of them.

Wu Shiqi left first on the grounds that he wanted to perform official duties of a bad person.

Song Shaoyuan and You Duzhi stood in front of the wall of Pingkangfang, feeling the warm sunlight covering their bodies.
The despair and helplessness in the pavilion house an hour ago was like a dream.

Suddenly a world away.

"Sunrise,"

Song Shaoyuan turned around to look at Li Ang, bowed to the end, and said with sincere gratitude, "This time. I'll trouble you. I'll go to the bank when I get back..."

"My brother, what are you talking about. Even for Aunt Song's sake, I can't leave you alone."

Li Ang waved his hand casually and glanced at You Xiao who was standing beside him, "You know, I have already told Jiao Cheng that you have left Lianhua Building and can move out.

After waiting for a while, he was completely freed from slavery, and he was able to ask someone to go to Lianhua Building to bring out his daily necessities.

If there is a personal maid or something to redeem, it can also be discussed. "

You Duzhi thanked Li Ang in every possible way. After being persuaded by Li Ang to stop him, he took a half step back and leaned on Song Shaoyuan gently like a bird.

The two looked at each other, and the love in their eyes almost melted each other.

'Aunt Song, I was wrong, Chang'an is really a devil's den that eats people and doesn't spit out bones'

Seeing that Song Shaoyuan was completely captured by love, Li Ang shook his head helplessly, called for a carriage, and carried the two back to the West City to notify Yang Yu and other classmates who were still waiting in the West City, and told them that the matter would calm down.

Also let Chai Cuiqiao at home not to worry.

Li Ang held the reins of the horse himself, and walked slowly westward, thinking about things casually.

The method of extracting mannitol from kelp under modern industrial conditions,
It has to undergo complex steps such as soaking, purification, acidification and oxidation, iodine extraction, evaporation, concentration, cooling crystallization, centrifugal separation, and drying.

The mannitol solution he had just extracted with the kelp soaking liquid was just a simple medicine under simple conditions.

Modern medicine is medicine based on modern science and modern industry.

Mannitol is already so difficult to obtain, and other rescue drugs such as epinephrine, cediline, sodium nitroprusside, and lidocaine are even more difficult to obtain.
The silver bell-like laughter of children interrupted Li Ang's thinking.

I saw a group of seven or eight-year-old children in the open space, whipping tops of different colors with ropes, making the tops collide with each other.

Gyro battle, right?
The corners of Li Ang's mouth raised slightly, inexplicably thinking of the childish behavior of secretly adding weights inside the top to increase the lethality in the top battle.

and many more
Gyro.
Centrifugal force? !

Li Ang's eyes suddenly lit up, and he suddenly thought of something.

Duke Yan's illness was saved.
