General Yunhui's Mansion is located in Xuanyangfang on the west side of Dongshi City. The speeding carriage stopped outside the gate. Li Wei jumped out of the carriage first, followed closely by Li Ang.
The two of them hurriedly saw the general's wife who was covering her face and crying, and the pale-faced Yunhui General Chen Changxiao himself, and rushed into the house.
The old man of the Chen family was lying on his back on the bed, his face was like gold paper, and he was breathing hard.
There was a long and narrow sword wound on the outside of his thigh, which was covered in blood.
Sitting next to the bed was a middle-aged telepathic master who had been invited temporarily. He was sweating profusely and releasing his telekinesis power, forcibly closing the gap in Chen Dalang's legs.
Despite this, the blood seeping from the wound still flowed all over the floor.
"A cut artery..."
Li Ang took a breath of cool air after checking the situation. Fortunately, the General's Mansion called for a spiritual master to stop the bleeding in time, otherwise the injury would have been enough to kill him ten times.
"Doctor, you must save Dalang, he is still young..."
"I try my best."
The patient's family members were completely useless in the room. Li Ang asked them to leave the house, took out a tourniquet from the medicine box to stop the bleeding of the injured, and then disinfected his palms and surgical tools.
Then Li Ang opened the wound and found the cut blood vessels, sutured them with catgut sutures that can be absorbed by the human body, and then used fine silver threads to suture the skin and flesh.
But Chen Dalang's will is still inevitably dim.
Pale and cold skin, tachycardia, weakened carotid pulse...
Li Wei asked in astonishment: "Why is Chen Dalang still not awake when the sun rises?"
"Blood loss exceeds 30% of the total blood volume, hemorrhagic shock."
Li Ang said quickly: "There are only three ways left now. One, drink the pulse and come back;
2. Give a large amount of isotonic balanced salt solution;
Three, blood transfusion."
Before Li Wei could ask what kind of magic medicine Pulse was, Li Ang went outside and found General Yunhui and his wife who were waiting anxiously. "General, Chen Dalang is in critical condition now and needs a blood transfusion to save him from shock."
Chen Changxiao said in shock: "Blood transfusion?"
"Transfuse part of other people's blood into patients who have lost blood, so that the heart, liver, spleen, lungs and kidneys that are about to fail can work again."
Li Ang said quickly: "It's equivalent to pouring fuel into the oil lamp again."
"Can I have a blood transfusion?"
Chen Changxiao took a breath and said, he had a son in middle age, and he doted on his children very much. This time, it was he himself who asked his eldest son to perform martial arts, and tragedy happened.
Naturally, we will not be entangled in the folk concept that "qi and blood are the foundation of human beings" at this time.
Li Ang shook his head and said: "The blood types may be different.
Depending on the blood type, agglutination may occur."
Li Wei's eyelids twitched and he asked hurriedly: "Is it the A, B, and C blood types you talked about today, Risheng?"
"What blood type?"
Chen Changxiao didn't understand why. Li Ang didn't have time to explain so much, so he turned to Li Wei and said, "It takes time to test the blood type. I'm afraid Chen Dalang can't wait so long."
"Then draw my blood for transfusion."
Li Wei looked serious and said quickly: "Risheng, haven't you been tested before? I have type C blood, and there are no A and B antigens in the blood.
Therefore, when blood of other blood types meets, agglutination will not occur."
Li Ang raised his eyebrows and said, "Are you sure?"
"Yeah."
Li Wei gritted his teeth, "Da Lang and I are brothers and sisters, even if we die..."
"It's just a blood draw, it won't be that serious. At best, it's like taking off your clothes in the swamp and getting bitten by leeches."
Li Ang patted Li Wei on the shoulder, took him back to the house, took out a cotton swab from the medicine box, disinfected Li Wei's wrist, and then used a syringe to slowly draw blood and transfuse it.
After everything was done, Li Ang sterilized his palms and surgical tools, then opened the door and walked out of the house, shaking his head at the restless General Yunhui and his wife.
Seeing Li Ang shaking his head, the general and his wife felt dizzy and dizzy, and subconsciously shouted, "Dalang!"
Li Wei, who chased after him with a cotton swab on his wrist, asked in a trembling voice: "Risheng, is blood transfusion still not enough..."
Li Ang said inexplicably: "Okay, I didn't say no."
Li Wei looked stunned, "Then why are you shaking your head..."
"My neck is sore after squatting beside the bed for too long."
After that, Li Ang ignored the wonderful expressions on the faces of the general, his wife and Li Wei, and said: "The shock due to blood loss has improved, but whether he can survive next depends on Dalang's own luck.
What's really fatal is wound infection."
"Infection?"
"It's just a malignant sore, festering."
Li Ang briefly explained the doctor's instructions, for example, the bandage wrapped around the wound must not be contaminated, it is forbidden to drink alcohol and eat spicy food during the recovery period, and eat more dates, oranges, milk, lean meat, etc.
The general and his wife sent Li Ang and Li Wei off with great gratitude, and even gave them a gift before leaving, but Li Ang refused.
So for major wounds, hemostatic suturing is just the beginning, and subsequent prevention of wound infection is the key.
In the absence of anti-inflammatory drugs and antibiotics, wound suppuration is basically equivalent to a suspended death sentence or even death penalty.
Sitting in the carriage of the General's Mansion, Li Ang thought about all the information about the inflammation of the wound, with a serious expression on his face, and murmured: "The monk Jing from the Boshu Temple yesterday was indeed half right.
What a bloody disaster."
"Risheng, you have done a great job."
Li Wei's blood was strong, and after a tube of blood was taken away, his face turned slightly pale.
Seeing Li Ang's frown, he comforted him: "I used to be a soldier in a border town, and my swords had no eyes on the battlefield. I don't know how many enemies there were, and my comrades died of blood loss due to being slashed.
The method of blood transfusion is unheard of,
In a situation like Chen Dalang's, if he could be saved, it would be Hua Tuo's reincarnation.
If you can promote it and rescue injured soldiers extensively, Your Majesty will not reward you enough."
"Really rescued Hua Tuo will be reincarnated.
It can’t be saved, it’s just quack medicine that harms people.”
Li Ang shook his head and sighed.
According to his plan, the emergency blood transfusion method should wait until the academic doctors have done enough relevant experiments before it can be put on the table.
Now the eldest son of General Yunhui has become the first subject of emergency blood transfusion. If he dies from subsequent wound infection, the emergency blood transfusion method may also be blamed for nothing.
If we want to eliminate people’s paranoid ideas about blood transfusion treatment, we don’t know how much effort it will take.
‘Is it necessary to produce anti-inflammatory drugs and antibiotics countless steps ahead of time?
Is it really possible under current conditions...'
Li Ang fell into deep thought. Anti-inflammatory drugs are drugs that can inhibit inflammatory reactions, and antibiotics are one type of anti-inflammatory drugs. They specifically refer to heterogeneous secondary metabolites produced by microorganisms or higher animals and plants that have anti-pathogen or other activities.
Synthetic and semi-synthetic anti-inflammatory drugs, whether they are paracetamol, ibuprofen, or metronidazole, etc., the synthesis process is too complicated.
I don’t know how many times more difficult it is to produce vitamin B12 than using pig liver.
And antibiotics——
Sulfa, chloramphenicol, streptomycin, and penicillin...
