Chapter 1756 Inclination Test

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

But he moved slightly, but sat down steadily. He didn't follow to get out of the car, but looked at Zheng Ren's back thoughtfully.

"Brother Yun, what is Boss Zheng doing?" Luan Yingjie asked anxiously.

"I'm buying medicine, can I go to the pharmacy to buy vegetables? Don't tell me, there are people who go to the hospital to buy barley, maybe the pharmacy also sells vegetables." Su Yun's answer was not serious at all.

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

"Brother Yun, you said that if I don't send my dad to the mental hospital, will his illness become more serious? Or should I live in a quadrangle? I'm really afraid that one day he can't think of it and jump from the upstairs." Luan Yingjie said distressedly.

"Yo, old Luan, I've been earning a lot these years, and there are courtyard houses." Su Yun saw Zheng Ren walk into the pharmacy, and began to fight with Luan Yingjie.

"My old house, isn't it waiting to be demolished? But he said that we need to protect cultural relics. You said, what is there to protect an old house?" Luan Yingjie said, "I will have to sort the garbage again after a while. …”

"Why did you get involved in garbage sorting again?" Su Yun said: "It's okay, I see the boss's expression as if it's not a big deal, you can rest assured."

"Brother Yun, there is a rumor from Pengcheng that it was Boss Zheng who cured a geographer's scourge. Is this really the case?" Although Luan Yingjie was anxious, but he couldn't leave at this time, so he had to talk to Su Cloud bullshit.

"What kind of geographer, he just takes a bath in the bathroom." Su Yun smiled and said, "Don't talk nonsense about this kind of feudal superstition."

"Uh..." Luan Yingjie was stunned for a moment, thinking that it was Brother Yun who was young and bold, and the geographer turned into a bather in his mouth.

Soon, Zheng Ren came out from the point and got back to the car.

"The price of nitroglycerin has risen." Zheng Ren said this in the first sentence after getting into the car.

Su Yun was surprised.

Doctor, who can go to the pharmacy to buy medicine? Now there is zero mark-up on medicines in hospitals, and medicines are cheaper than pharmacies. Except for queuing and registration, there are no other disadvantages.

The price increase of nitroglycerin has no effect on the boss at all, okay?

"How much did it go up?"

"10 times? 20 times?" Zheng Ren said.

"..." Su Yun didn't know much about this, and was startled all of a sudden.

"In the past, nitroglycerin used to be a big bottle. I don't know how many capsules were in it. Sometimes patients were asked to buy it at the pharmacy themselves." Zheng Ren said, "Now there are no cheap big bottles, only this finely packaged one is left. . The packaging is 95% of the retail price, you talk about…”

"Don't talk nonsense, just tell the truth." Su Yun said, "What do you buy nitroglycerin for?"

"Do a tilt test." Zheng Ren said.

"Tilt test? Is it to see if my dad's brain works or not? Or is his body flexible?" Luan Yingjie asked, "Boss Zheng, what you just said about mental..."

"It's an autonomic nerve, not a spirit." Zheng Ren corrected, "Now that it's not a mental illness, don't talk nonsense."

Why does Boss Zheng speak with the same attitude as his own son, but he is someone else?

Luan Yingjie was a little surprised.

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

"Um."

"Then what are we going to do?" Su Yun was puzzled.

"Take a look, and in order to increase the effect of the tilt test, the performance of nitroglycerin is more obvious." Zheng Ren said, "I am worried that the old man will be temporarily uncomfortable and cannot be handled at home."

"You don't have anything," Su Yun said.

"Call 120 for first aid." Zheng Ren said, "Let Zhou Litao come directly with the first aid kit. If something really happens, he can deal with it immediately."

"Do you consider this a public tool for private use?" Su Yun sprayed.

"Patients, as long as the resources are used on the patients, it is not considered." Zheng Ren said, "If I go out to play in the 120 ambulance, it will be regarded as a public tool for private use."

"Don't tell me, I heard from the teacher that in the first 20 years he went to Feidao, and the local hospital drove the 120 ambulance to go out to play." Su Yun said with a smile.

"It's gone now, and even 120 emergency services can't get through." Zheng Ren said.

Luan Yingjie was a little anxious when she heard the two chatting here, so she took the time to interrupt the conversation between the two and asked, "Boss Zheng, what is a tilt test?"

"Uh..." Zheng Ren thought for a while, it was very troublesome to explain, but when the patient's family asked, he couldn't say nothing.

Let's talk about it for a while to do the tilt test with nitroglycerin, but there are still some fluctuations, and the family of the patient should also cooperate.

"Let's put it this way, Boss Luan." Zheng Ren said, "When the human body is upright, 300~800ml of blood accumulates in the lower extremities due to the action of gravity, which causes the central venous pressure, stroke volume and arterial blood pressure to drop, and reflexively causes sympathetic nervous tension. Elevated, manifested as an increased heart rate, a mild decrease in systolic blood pressure, and a mild increase in diastolic blood pressure.”

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

"Yes, I have."

"The first thing I do when I wake up every morning is to measure my blood pressure. Lying on the bed or lying down is because the blood pressure is unstable when standing. That's what the boss said just now."

Er, explain it in human words, Luan Yingjie will understand immediately.

Su Yun was also helpless. The boss should be looking forward to doing the test right away, and the explanation was too professional.

"Well, that's basically it. I think your father has autonomic function problems." Zheng Ren continued: "The degree of blood accumulation in the lower extremities of patients with vasovagal syncope is more serious than that of normal people when they stand upright, the central venous pressure is significantly reduced, and the amount of blood returned to the heart is reduced. decreased, and sympathetic tone continued to increase."

Luan Yingjie half understood.

"This then results in a marked increase in ventricular contractility, overstimulation of baroreceptors in the posterior inferior wall of the left ventricle, resulting in a reflexive decrease in sympathetic tone, vasodilation, a drop in blood pressure, sudden cerebral ischemia, syncope, and sometimes with increased vagal tone. , bradycardia."

"Boss, do you have any research on the unmyelinated C nerve fibers?" Su Yun asked suddenly.

"Have you studied it? Using mice in the laboratory?"

"Well, it's interesting." Su Yun smiled proudly: "I cut it off..."

Next, Luan Yingjie listened to Su Yun's story of cutting off the unmyelinated C nerve fibers of mice in the laboratory, as if listening to a book from heaven.

20 minutes later, when the car arrived home, Zheng Ren got off the car and called.

He called Zhou Litao first, asked if the other side was busy, and then talked about his own situation.

Zhou Litao was simply too interested. He felt that Boss Zheng was really honest. When encountering a patient who fainted after eating, he did not forget to ask himself to come out and take a look.
