Chapter 1757

"The patient has no coronary heart disease!" Su Yun habitually said.

But he moved slightly and sat down steadily. Instead of getting off the bus, he looked at Zheng Ren's back and thought deeply.

"Brother Yun, what is boss Zheng doing?" Luan Yingjie's square inch has been disordered and asked anxiously.

"Buy medicine. Can you buy vegetables at the drugstore? Don't tell me. Some people buy job's tears at the hospital. Maybe the drugstore also sells vegetables." Su Yun's answer was not serious at all.

"..." Luan Yingjie didn't know how to answer for a moment.

"Brother Yun, you said if I didn't send my father to a mental hospital, would his illness be more serious? Why don't I change to a quadrangle? I'm afraid he'll jump from upstairs one day." Luan Yingjie said in distress.

"Yo, Lao Luan, I haven't earned less these years. There are quadrangles." Seeing Zheng Ren walking into the drugstore, Su Yun began to laugh with Luan Yingjie.

"The old house of my family is waiting to be demolished. But I say I want to protect cultural relics. You say, what can an old house be protected?" Luan Yingjie said, "after a while, I will classify the garbage again, I......"

"Why are you talking about garbage sorting again." Su Yun said: "it's all right. I think the boss's expression should be no big deal. Don't worry."

"Brother Yun, it's said from Pengcheng that boss Zheng cured the scourge of a local division. Is there really such a thing?" Luan Yingjie was worried, but he couldn't go at this time, so he had to talk nonsense with Su Yun.

"What local teacher, is a bathhouse to take a bath." Su Yun said with a smile, "don't talk nonsense about this feudal superstition."

"Er..." Luan Yingjie was stunned for a moment, thinking that Brother Yun was young and brave, and the earth teacher turned into a bath in his mouth.

Soon, Zheng Ren came out of the main point and returned to the car.

"Nitroglycerin has gone up in price." After Zheng Ren got on the bus, the first sentence was this.

Su Yun was surprised.

Doctor? Who's okay? Go to the drugstore to buy medicine? Now hospital drugs are zero plus. Drugs are cheaper than pharmacies. There are no other disadvantages except queuing and registration.

The price rise of nitroglycerin has no effect on the boss.

"How much has it gone up?"

"10 times? 20 times?" Zheng Rendao.

"..." Su Yun was shocked because he didn't know much about it.

"In the past, nitroglycerin was a large bottle. I don't know how many tablets there were. Sometimes patients were asked to buy them at the drugstore." Zheng Ren said, "now there are no cheap big bottles, only this kind of fine packaging. Packaging accounts for 95% of the retail price. Tell me..."

"Stop talking nonsense and get down to business." Su Yun said, "what do you buy nitroglycerin for?"

"Tilt test." Zheng Rendao.

"Tilt table test? Is it to see if my father's brain is easy to use or whether his body is flexible?" Luan Yingjie asked, "boss Zheng, what you just said is spiritual..."

"It's the autonomic nerve, not the spirit." Zheng Ren corrected, "now it's not a mental disease. Don't talk nonsense."

Why does boss Zheng speak like he is his own son, but he is someone else?

Luan Yingjie was a little surprised.

"The patient's upright response is similar to the syncope in clinical practice, so it is used to assist in the diagnosis of vasovagal syncope. Is this?" Su Yun asked.

"Yes."

"Then why do we follow?" Su Yun doesn't understand.

"Take a look, and in order to increase the effect of tilt test, it is more obvious to take nitroglycerin." Zheng Ren said, "I'm worried that the old man will have a sexual discomfort, which can't be handled at home."

"You have nothing." Su yundao.

"Call 120 first aid." Zheng Ren said, "let Zhou Litao come directly with the first aid kit. If there's something really wrong, you can deal with it immediately."

"Is this a public instrument for private use?" Su Yun sprayed it.

"Patients, as long as resources are used on patients, they are not." Zheng Ren said, "if I drive a 120 ambulance out to play, it's for public and private use."

"Don't tell me yet. I heard from the teacher that he went to the Throwing Knife in the first 20 years. The local hospital drove 120 emergency vehicles to play." Su Yun smiled.

"Now there is no 120 first aid." Zheng Rendao.

Luan Yingjie listened to the two people chatting here. He was a little anxious. He took the time to interrupt their dialogue and asked, "boss Zheng, what is tilt test?"

"Er..." Zheng Ren thought for a moment. It was troublesome to explain, but when asked by the patient's family, he couldn't say nothing.

In addition, there are still some waves when taking nitroglycerin for tilt test, which also needs the cooperation of the patient's family members.

"Let's say so, boss Luan." Zheng Rendao: "when the human body is upright, due to the action of gravity, 300 ~ 800ml of blood accumulates in the lower limbs, resulting in the decrease of central venous pressure, stroke output and arterial blood pressure. Reflex causes the increase of sympathetic nerve tension, which is manifested in the increase of heart rate, the slight decrease of systolic blood pressure and the slight increase of diastolic blood pressure."

Seeing Luan Yingjie's confused face, Su Yun interrupted Zheng Ren and said, "do you have a friend with high blood pressure?"

"Yes."

"The first thing I do when I get up every morning is to take my blood pressure. Lying in bed and lying flat is because my blood pressure is unstable when I stand. That's what the boss just said."

Er, explain it in human words. Luan Yingjie immediately understood.

Su Yun is also quite helpless. The boss should be looking forward to doing the experiment immediately. The explanation is too professional.

"Well, basically. I think your father has autonomic nerve function problems." Zheng Ren continued: "when patients with vasovagal syncope stand upright, the blood accumulation of lower limbs is more serious than that of normal people, the central venous pressure decreases significantly, the amount of return heart blood decreases, and the sympathetic tension continues to increase."

Luan Yingjie didn't understand.

"Then it leads to a significant increase in ventricular contractility and over stimulation of the baroreceptors in the posterior lower wall of the left ventricle. As a result, it reflexively causes a decrease in sympathetic tension, vasodilation, decreased blood pressure, sudden cerebral ischemia, syncope, sometimes accompanied by increased vagal tension and bradycardia."

"Boss, have you studied the unmyelinated C nerve fibers?" Su Yun suddenly asked.

"Have you studied using mice in the laboratory?"

"Well, that's interesting." Su Yun smiled proudly and said, "I cut off..."

Next, Luan Yingjie listened to Su Yun's story about cutting off the unmyelinated C nerve fibers of mice in the laboratory.

After 20 minutes, the car drove home, Zheng Ren got off and called.

He first called Zhou Litao, asked if he was busy, and then said his situation.

Zhou Litao was so interested that he thought boss Zheng was really righteous. When he met a patient who fainted at dinner, he didn't forget to ask himself to run out and have a look.
