After being scolded by her, Li Xiaobing and Teacher Lu did not dare to move.
The two of them could only watch nervously what Xie Wanying was going to do alone.
Heart compressions? Or heart hammering?
Xie Wanying's fingers touched the patient's neck. The other two people judged that she wanted to touch to diagnose whether the carotid artery pulse had disappeared. Unexpectedly, after her index and middle fingers came together, they slid from the thyroid cartilage to the patient's spine. After touching the carotid artery, she suddenly
Stopped there and pressed.
What is she doing? Li Xiaobing and Teacher Lu blinked.
One, two, three, four, five. After reciting five times in her mind, Xie Wanying immediately moved her finger away from that position.
The patient's symptoms were seen to have stopped.
Li Xiaobing and Teacher Lu, who were watching from the sidelines, could only think of one sentence: Is this a god?
What's going on? People who are not in the cardiology department probably didn't see it or couldn't figure it out.
I just heard a dull and cold man's voice next to me: "You——"
The three people at the scene raised their heads and discovered Fu Xinheng and Zhou Junpeng standing on the patient's head.
Maybe the scene was so tense that the three of them didn't notice anyone coming.
"Teacher Fu." Xie Wanying immediately called her teacher.
Fu Xinheng and Zhou Junpeng came over at a trot. Their breathing had not calmed down completely, and their heartbeats had not recovered from the shock of watching her perform first aid operations. That was why Fu Xinheng said half of what you said just now.
It suddenly hit him and he didn't know what to say. Maybe at this moment, if he wanted to say something to her, he had to first remember the unfortunate experience of being slapped in the face. That time he told her not to follow her into the operating room, and then
I used the ideas she mentioned to save people in the operating room.
Thinking of this, Fu Xinheng's thin lips pursed into a line that required caution in words and deeds.
Rolling over in front of students will affect the teacher's prestige. Suddenly he understood why Tan Kelin's silence was golden.
Zhou Junpeng, who was holding his knees, waited for a while. He thought Fu Xinheng was going to curse, but after waiting for a long time, he felt strange.
They are specialist doctors, so they are absolutely certain. Teacher Bilu and Li Xiaobing knew exactly what operation Xie Wanying was doing. So they walked and found an abnormality halfway. The two of them ran over with a quickening pace and put the cart on
Another group of people with beds and wheelchairs were left behind.
What Xie Wanying just did: massage the carotid sinus.
God, Zhou Junpeng thought to himself that she was really brave, or that she didn't know anything to dare to use this operation to rescue the patient.
Massaging the carotid sinus changes arterial blood pressure through baroreceptors. Let’s first talk about the anatomy of the carotid artery. The terminals of sensory neurons extend along the internal carotid artery and have a section just at this position. Massage here
, can cause sympathetic nerve suppression and parasympathetic nerve stimulation, and significantly lower blood pressure and heart rate.
This action may seem magical, but in fact it is risky. Foreign heart associations stipulate that only doctors can perform it, and ordinary first responders cannot perform it. And the only indication for treatment is paroxysmal supraventricular tachycardia.
Any medical operation has a designated standardized process, which is summed up by the bloody and tearful experience of many clinicians and patients, in order to prevent misoperation. Once a mistake is made, in medicine, it will kill people instead of saving lives.
Specific to the operation of massaging the carotid sinus, the Foreign Heart Association recommends that it be performed under ECG monitoring, leaving an intravenous catheter for the patient, and keeping various emergency drugs nearby in case of an accident.
