Chapter 955: 【955】Risk Operation
Reprimanded by her, Li Xiaobing and Teacher Lu dared not move.
The two could only watch Xie Wanying nervously, wondering what she was going to do on her own.
Would it be chest compressions? Or precordial thump?
Xie Wanying’s fingers reached for the patient’s neck. The other two guessed she was trying to feel whether the carotid pulse had disappeared. Unexpectedly, after her index and middle fingers ca together, they slid from the thyroid cartilage to the patient’s spine, and upon finding the carotid artery, she suddenly stopped there and pressed down.
What was she doing? Li Xiaobing and Teacher Lu blinked.
One, two, three, four, five. After silently counting to five, Xie Wanying imdiately moved her fingers away from that spot.
Seeing that the patient’s symptoms had halted.
Li Xiaobing and Teacher Lu could only think to themselves, was this so kind of miracle?
What’s going on here? Those not specializing in cardiology might not be able to recognize or think of the rationale at a glance.
They only heard a dull, cold male voice chi in, “You—”
The three people at the scene lifted their heads, noticing Fu Xinheng and Zhou Junpeng standing at the patient’s head.
Perhaps the scene had been too tense; they hadn’t realized that soone had arrived.
“Teacher Fu,” Xie Wanying imdiately greeted him.
Fu Xinheng and Zhou Junpeng had hurried over, their breathing not yet fully stabilized, and their hearts still hadn’t recovered from the shock of watching her perform the ergency procedure. This caused the hesitation Fu Xinheng experienced before finishing his sentence.
He suddenly didn’t know what to say. Perhaps in that instant, he had to rember the unfortunate experience where he had been embarrassingly proven wrong. That ti, he had told her not to enter the operating room, and then ended up using her approach to save a life inside.
Thinking of this, Fu Xinheng’s thin lips ford a line, reminding himself to be extra cautious with his words.
A mistake in front of students could damage a teacher’s authority. Suddenly he understood why Tan Kelin believed silence was golden.
Zhou Junpeng, supporting both knees, waited a while, expecting Fu Xinheng to start scolding, but when none ca, he began to feel puzzled.
They were specialists and knew for sure, better than Teacher Lu and Li Xiaobing, what procedure Xie Wanying had just perford. That’s why they started walking faster upon spotting an anomaly halfway there, leaving the others with their carts and wheelchairs trailing behind.
What Xie Wanying had done was: carotid sinus massage.
My god. Zhou Junpeng thought she must either be incredibly bold or ignorant to dare to use this procedure in an ergency.
Carotid sinus massage works by changing arterial blood pressure through pressure receptors. First, it’s necessary to talk about the anatomical principle here, where the nerve endings along the internal carotid artery extend to this particular spot. Massaging this area can cause inhibition of the sympathetic nervous system and stimulation of the parasympathetic nervous system, significantly lowering blood pressure and heart rate.
This action may seem miraculous, but it’s actually risky. The international cardiology associations have stipulated that only a physician may perform it, and it’s not allowed for general ergency responders. And, there is only one specific therapeutic indication for it: paroxysmal supraventricular tachycardia.
Every dical procedure follows certain standard protocols, which are the result of countless clinicians and patients’ bloody and tearful experiences, ant to prevent misoperations. A wrong move in dicine can result in death, not salvation.
Specifically for carotid sinus massage, international cardiology associations recomnd to perform it under electrocardiographic monitoring, to have an intravenous catheter ready for the patient, and to prepare various ergency dications in case sothing goes wrong.
