Teach a man to fish
"First of all, why do we have to hang the bottle high up?" Su Yunwei pointed to the infusion bottle hanging upside down on the golden hook. "This is called utilizing the static pressure of the liquid. The higher it is hung, the greater the pressure generated. Only then can we overcome the pressure in our human veins and allow the medicine to flow smoothly into the blood vessels. If it is hung too low, or level with the arm, the medicine will not be able to flow in. The blood will even flow back into the tube." She said while using gestures to indicate the difference between high and low pressure.
Fu Changan listened intently, his eyes following the movement of her fingers. These principles were new to him, yet they were logically coherent and self-contained. He nodded slightly, indicating his understanding.
On the battlefield, he was well aware of the terrain's ups and downs. This theory of static pressure seemed to be similar to the art of looking down from a high position in military strategy, except for the different division of labor.
"Secondly, one of the most important steps is to expel the air from the inside before the medicine enters the body." Su Yunwei's expression became extremely serious. She picked up another unopened infusion set to demonstrate. "Look, there's air inside this long, thin tube. If a large amount of air enters the blood vessels with the medicine, it can flow through the bloodstream to the heart or brain, forming an embolism and blocking important blood vessels. That can be fatal. It's extremely dangerous."
"Embolysis..." Fu Changan repeated the unfamiliar, deadly word, his eyes tightening as he etched the words "exhaust all air" firmly into his mind. This seemingly soft, thin plastic tube unexpectedly held such a deadly intent.
Under Fu Changan's watchful eyes, Su Yunwei manipulated the liquid medicine in the infusion bottle into the hose, and then expelled the air from it: "Look, the needle here is discharging a continuous stream of liquid medicine, not intermittent liquid with bubbles. This is considered to be completely discharged." Finally, she quickly turned off the regulator and carefully placed the air-expelled needle aside for use.
Then he sat down beside the bed and reached out to hold Mingzhao's hand: "You hold his hand. Just like I do." Su Yunwei said to Fu Changan, then turned to Mingzhao and said in a slower tone, "Mingzhao, relax, and try not to use too much force."
Ming Zhao was unsure what to do, but he still let Fu Chang'an hold his hand. His hand was pale and thin, and the veins beneath the skin were almost visible. Fu Chang'an took his wrist as he was told. It was icy cold, and he could clearly feel the subtle pulse beating under his hand, as well as Ming Zhao's trembling.
For some reason, Fu Changan's own hands were also cold.
Seeing that Fu Changan had grasped the hand, Su Yunwei picked up the tourniquet beside him and tied Mingzhao's hand.
"What is this?" Fu Changan asked.
"This is called a tourniquet. As the name suggests, it can stop bleeding. It can also make the blood vessels more visible, making it easier for you to puncture."
After saying that, Su Yunwei picked up an iodine-filled cotton swab and carefully disinfected the back of Ming Zhao's hand. The cold touch made Ming Zhao flinch. "It needs to be disinfected before puncture." Fu Changan stared at her disinfected cotton swab and nodded silently.
"Look carefully at the location of the blood vessel." Su Yun pointed to the most obvious blue vein on the back of Ming Zhao's hand. "Insert the needle tip at an angle. If you see blood returning, it means it's successful. Then, flatten the needle a little and push it in a little bit to secure it."
Su Yunwei explained it very carefully, then looked at Fu Changan: "Have you remembered it? Come and try it."
Fu Chang'an took a deep breath and took the needle with the capillary tube that Su Yunwei handed him. His hands were steady, as steady as a rock, whether he was drawing a bow and shooting an arrow or swinging a sword to kill an enemy. But at this moment, his hands couldn't help but tremble. This made him more nervous than facing an army of thousands.
Ming Zhao's once dead eyes were now filled with uncertainty. He stared at the approaching needle tip, his body instinctively wanting to retreat, but Fu Chang'an held him tightly. He looked at Fu Chang'an, who was concentrating and looking as if he were facing a formidable enemy, and then at Su Yunwei, who stood beside him with a serious expression. The despair of wanting to die and the silence of the world in his heart were strangely alleviated by this novel scene.
what are they doing? ?
Can such strange medical skills really save lives?
Fu Chang'an held his breath and followed Su Yunwei's instructions. He placed the needle tip against the disinfected skin. He could feel Ming Zhao tense, and he could also feel his own heartbeat racing. He applied a slight pressure with his wrist, and the needle tip pierced the skin, feeling a subtle resistance.
"Go in a little further, and make the angle a little lower... That's right!!" Su Yunwei stared closely and gave instructions in a low voice.
Suddenly, a tiny stream of bright red blood suddenly flowed back into the transparent tube.
"It's healing! Great! It worked!" Su Yunwei exclaimed immediately, her tone encouraging, "Fix it. Use tape."
Fu Changan breathed a sigh of relief almost immediately. Following the tape Su Yunwei quickly handed him, he frantically but carefully fixed the needle. After doing this, a light sweat broke out on his forehead, as if everything that had just happened had been a difficult battle.
Ming Zhao stared blankly at the strange device fixed on the back of his hand, and watched as unknown liquid in the transparent tube was injected into his body drop by drop, bringing a slightly cool feeling.
The expected severe pain did not occur, only a slight stinging sensation when the needle entered. This unprecedented treatment method exceeded all his cognition.
Deep in the originally empty eyes, a faint light of curiosity could not help but ignite.
So... there's such a method in this world? So, the blood vessels in the body can be used to deliver life-saving potions? Is this... the thing that can save him?
Su Yunwei adjusted the dripping speed, nodded with satisfaction, and looked at Fu Changan with praise in his eyes: "General Fu is a fast learner. He succeeded in the first puncture. He is really talented."
Although he was nervous and unfamiliar with the process, the result was quite perfect.
When I first performed a puncture on a patient, my colleagues teased me, saying I was just a show-off who was better at theoretical knowledge than practical application.
Upon hearing this, Fu Changan subconsciously straightened his back. The tension he had just felt instantly dissipated, replaced by a sense of satisfaction of recognition. This was completely different from the feeling of being recognized for the first time on the battlefield.
He coughed lightly and his expression returned to its usual calmness, but a hint of smile and...interest flashed across his eyes.
This medical technique called infusion is indeed extraordinary.
Ming Zhao's gaze lingered on the back of his hand for a long time. The subtle ticking of the water seemed to hammer into his broken heart, enveloping it completely. Finally, he slowly closed his eyes.
No one knew what he was thinking, but the trembling shadow cast under his eyelashes seemed to silently stir the stagnant water.
"This bottle of medicine today is the last one. Once it's all used up, there will be no more." Although Su Yunwei was reluctant to give up the medicine, she was still slightly relieved that Mingzhao's health had improved. At least in this era, these bottles of antibiotics had played their final role. From now on, there would be no more antibiotics to use.
I hope Mingzhao will not let Mingyue down, nor will he let these precious antibiotics down.
"Ming Zhao, I look forward to seeing you get better."
Su Yunwei's voice reached Ming Zhao's ears. His tightly closed eyes trembled slightly, and then he slowly opened his eyes and looked at Su Yunwei.
He said, "If I recover, would you please grant me a favor?"
Su Yunwei: "What?"
Ming Zhao did not answer immediately. He was silent for a moment. Just when Su Yun was wondering if he was hallucinating, he finally spoke: "I wonder if I could become your disciple and learn the art of Qi Huang medicine?"
For a moment, Su Yunwei was a little surprised. This was the third person who said he wanted to learn medicine from him. Western medicine was indeed wonderful, but compared with traditional Chinese medicine, it always felt like a small witch compared to a big witch. Besides, with his half-baked level, how could he teach others everywhere? Fu Changan was of course different. He agreed to him that night purely because the atmosphere was right that night and he wanted to flirt with him, but today...
She was about to refuse when Fu Mingyue rushed in from outside, excitedly saying, "Promise him, Weiwei, Weiwei, promise Mingzhao, he's very smart."
"It's not that I don't want to agree, but my level is limited. I can't teach him anything." Even if I taught him, the resources in my hands are limited. He got the knowledge and methods, but he had no medicine and no tools. It was all just talk on paper. What use would it be?
"You just look down on me." Ming Zhao's heart, which had just opened up, was suddenly brought back to its original state.
Sure enough, prejudice cannot be eliminated in a short time.
Alas, Su Yunwei really wanted to look up to the sky and sigh. If it weren't for the life she had saved with great effort, she really wanted to turn around and leave. She really didn't want to take on an apprentice.
Of course, except Fu Changan.
"Okay, okay," Su Yunwei said helplessly, "I promise you."
"But I have a condition."
Fu Changan stood aside and listened silently. She had conditions. Did she have conditions for every student she accepted? He thought that condition only belonged to him.
“I have to collect tuition.”
Knowledge is priceless, but Su Yunwei's knowledge comes at a price.
Although Ming Zhao didn't know what request she could make at the beginning, as soon as she said her request, his heart, which had been hanging in the air, settled down. He didn't have anything else, but he had a lot of money. People in their line of work often donated generously to guests, and Madam Chun Ji was also kind-hearted and only took a small profit of three-tenths.
"I'll pay, I'll pay, no matter how much you want." Fu Mingyue spoke first, excitedly.
But what followed was Ming Zhao's rejection: "Mingyue, thank you very much for everything you have done for me during this period, but let me take care of this gift of cultivation myself."
Fu Mingyue wanted to argue, but was stopped by Su Yunwei. She said, "Well, when you get better, come to the Fu Mansion to find me." She turned her eyes to Fu Changan and said cunningly, "Oh my, it's only been one day, and I found you a new junior brother. As the eldest brother, shouldn't you show your appreciation by giving the newcomer a red envelope?"
"Of course!" Fu Changan looked at her sparkling eyes, his heart moved slightly, "But I didn't know I needed to prepare a gift. I will give it to you when I return home."
Su Yunwei: "You don't have to give it!"
Fu Changan was stunned: "Why?"
Su Yunwei: "Just think of it as... a benefit for you being the eldest senior brother."
Women love money, but they should get it in a proper way.
He can pay it back with something else later!
