Chapter 955 [955] Risky Operation
After being scolded by her, Li Xiaobing and Teacher Lu didn't dare to move.
The two of them could only nervously watch what Xie Wanying was going to do alone.
Cardiac compressions? Or a heart hammering?
Xie Wanying's fingers touched the patient's neck. The other two judged that she was going to touch to diagnose whether the carotid pulse disappeared. Unexpectedly, after putting her index finger and middle finger together, she slid from the thyroid cartilage to the patient's spine, and after touching the carotid artery, she suddenly stopped there and pressed down.
what is she doing? Li Xiaobing and Teacher Lu blinked.
One two three four five. After thinking five times in her heart, Xie Wanying immediately moved her finger away from that position.
See the patient's symptoms stopped.
Li Xiaobing and Teacher Lu who were watching from the side could only think of one sentence: Is this a god?
What's the matter? It is estimated that non-cardiologists could not see or think of the way for a while.
I only heard a dull and cold man's voice next to me: "You—"
Three people at the scene raised their heads and found Fu Xinheng and Zhou Junpeng standing on the head of the patient.
Maybe the scene just now was too tense, and the three of them didn't realize that someone was coming.
"Teacher Fu." Xie Wanying immediately called out to the teacher.
Fu Xinheng and Zhou Junpeng trotted over, their breathing hadn't completely calmed down, and their heartbeats hadn't recovered from the shock of watching her perform the first aid operation just now.
It was all of a sudden that he didn't know what to say. Maybe at this moment, if he wants to say something to her, he must first remember the unfortunate experience of being slapped in the face. That time he told her not to follow into the operating room, and then used the idea she said to save people in the operating room.
Thinking of this, Fu Xinheng's thin lips became a line that required careful words and deeds.
Turning over in front of students will affect the prestige of the teacher. Suddenly he understood why Tan Kelin's silence was golden.
Zhou Junpeng, who was holding on to his knees, waited for a while, thinking that Fu Xinheng was about to curse, but he felt strange after waiting for a long time without him.
They are specialist doctors, so they are absolutely sure. Teacher Bilu and Li Xiaobing knew exactly what operation Xie Wanying was doing just now. That's why they walked and found something abnormal halfway, and the two of them ran over at a brisk pace, leaving the other group of people pushing the lathe bed and wheelchair behind.
What Xie Wanying just did was: massage the carotid sinus.
sky. Zhou Junpeng thought to himself that she was really daring, or that she dared to use this operation to rescue patients because she didn't understand anything.
Massaging the carotid sinuses alters arterial blood pressure by means of baroreceptors. First of all, we need to talk about the anatomical principle of the carotid artery. The end of the sensory neuron is just in this position after extending along the internal carotid artery. Massaging here can cause sympathetic nerve inhibition and parasympathetic nerve stimulation, which can significantly lower blood pressure and heart rate.
This action seems miraculous, but it is actually risky. Foreign heart associations stipulate that only doctors can do it, and ordinary first-aid personnel are not allowed to do it. And there is only one treatment indication called paroxysmal supraventricular tachycardia.
Any medical operation has a specified standard process, which is summed up from the experience of many clinicians and patients, in order to prevent misuse. Once a mistake is made, medically it is killing, not saving lives.
As for the operation of massaging the carotid sinus, the foreign heart association recommends that it be carried out under the monitoring of ECG, and the patient should be provided with a venous catheter, and all kinds of emergency medicines should be prepared next to it in case of accidents.
