Chapter 303: : Blood pressure is almost gone!

The night of an emergency department never makes people feel peaceful.
The worst thing to think about here is.
For example, at this time, Chen Cang just lay down for less than 10 minutes. When the snoring sounded, a violent knock on the door suddenly sounded!
It only took less than 5 seconds for Chen Cang to open his eyes, turn over to get out of bed, and then open the door urgently.
After the door opened, Xiao Lin stood outside.
Kobayashi panicked and said in a hurry: "Doctor Chen, it's not good, a man riding a motorcycle on the pipeline bridge hit the pipe next to us. We are closest to here and we are preparing to send a car. We need a follower Doctor Che! "
Chen Cang's face changed, and he walked outside and said, "Hurry to call Wang Yong, his second line, let him hurry up, I will follow and look at it."
Kobayashi nodded quickly: "Okay!"
Chen Cang rushed into the ambulance with anxiety. The driver Liu Liu was ready and ready to go anytime and anywhere.
After Chen Cang sat down, the car ran out instantly.
The pipeline bridge is the closest to the Second Provincial People's Court, less than 2 kilometers, but the most terrible is not this distance.
It's just that the pipeline bridge can't walk!
Pipeline bridge Pipeline bridge is actually a small bridge repaired for the pipeline between two rivers. People usually walk around the bridge.
Can walk at most electric bicycles or something, can't go cars at all.
The car can only drive to the side of the road, and it is necessary for the doctor to run up. There is still a long way to go from the road to the bridge. This is undoubtedly a serious obstacle for rescue!
It took less than two minutes for the car to reach the parking place immediately. Chen Cang opened the door and ran down, holding the first aid box, while the driver Lao Liu pushed the push bed on the 120 car down.
I was about to go up, but found that it was all stairs. The cart couldn't get down at all. I quickly rushed to hold the stretcher in my arms.
It's more than one in the morning!
There was no pedestrian on the road.
After waiting for Chen Cang and the driver Lao Liu to run over the pipeline bridge, they saw two young guys standing by their side, holding a mobile phone in their hands and making a call.
And a motorcycle fell aside, a man lying on the ground, life and death unknown!
However, seeing the destruction of the fence, Chen Cang sank inside!
Hit it like this!
Human ... is also very dangerous.
Chen Cang couldn't think much, and hurried forward with the driver.
The two young men saw Chen Cang in white hurriedly rushing, their eyes flashed.
"Doctor! Right here!"
At this point, the injured person lie on the railing, half of the body is on the bridge, and may fall off without notice!
The streetlights here are not very bright, only vaguely visible!
No blood on the road.
There should be no trauma ...
However, looking at the man like this, the most worrying thing is whether there is a fracture of the head and neck.
Once there, this transfer can be very troublesome.
However, in such a posture, there is really no way to rescue, and the man must be removed.
Chen Cang patted the man's shoulder: "Comrade! Wake up!"
"Can comrades hear?"
...
Chen Cang called several times in his ear, and saw no response.
Greet everyone: "Let's lift him down, Lao Liu, holding your waist, I'll get my head off, that ... lad, you two will help you hold your hands and lift your legs."
The two were not too old. They might be in their eighteenth or nineties, but they walked on the bridge in the middle of the night without sleeping.
Chen Cang couldn't think of anything else. At this time, saving people was his only idea now.
Transporting patients is very particular.
Such a car accident injury, it is easy to have a fracture of the body, especially the head and neck, cervical spine ... These places are injured.
Once the mode of transport is inappropriate, it is easy to cause secondary damage and even worsen the disease.
Therefore, in the face of unexpected patients, do not rashly transfer, otherwise it is easy to do bad things with good intentions.
The two young people did the right thing!
Transferring the patient to the stretcher, Chen Cang opened the first aid box, quickly checked the blood pressure, and then took out patient observation of breathing and pulse ...
At this time, the two young people saw that the street light was not very powerful, and simply turned on the flashlight of the mobile phone to illuminate the patient.
It didn't take long for the blood pressure to come out. After seeing the value, Chen Cang suddenly changed his face!
"60 / 30mmHg!"
This blood pressure, what is it about hypotension shock?
Thinking of this, Chen Cang suddenly changed his face.
Hypotension shock ... trauma ...
Is there bleeding?
But I didn't find the bleeding place for a long time!
What would it be
Chen Cang suddenly saw where the flashlight was shining and saw a strange phenomenon.
Chen Cang quickly said, "Give me the flashlight!"
The guy on the side was very cooperative and handed the flashlight over.
Chen Cang quickly looked down!
Jugular vein anger? !!
Suddenly, an emergency case appeared in Chen Cang's mind. At this moment, it must be verified!
Chen Cang handed the phone to the other party, and hurriedly took out his stethoscope.
My hands are a little tight.
After all, this disease Chen Cang has heard of, but has never encountered it. If so, the scene may have to immediately organize rescue.
Can't afford the delay!
Thinking of this, Chen Cang brought his listener and placed it in the heart of the injured chest area ...
Suddenly, a heartbeat of low and distant heartbeats came, and the speed was fast, like a drum sound ten miles away.
Chen Cang looked dignified!
It should be ... a triad of pericardium!
This is an acute critical illness: acute cardiac tamponade, Beck's triad with typical symptoms.
Mainly manifested by elevated venous pressure leading to increased jugular pressure and jugular venous distension, which is the first feature.
Second, a sudden drop in blood pressure leads to a decrease in systolic blood pressure, a decrease in pulse pressure difference, shock, and odd pulses. This is the second sign.
The third is a decrease in stroke volume, distant heart sounds, and tachycardia. This is the third sign.
The three signs seem to have put the truth before Chen Cang!
At this point, Chen Cang touched the skin of the injured person, feeling that the skin temperature was falling continuously.
Chen Cang has determined that the patient must be suffering from acute pericardial tamponade caused by trauma. He is currently in shock and is in an urgent situation with danger to his life at any time.
What is pericardial tamponade?
The heart is the power organ that maintains human blood circulation. It guarantees the blood supply to all organs and tissues in the body.
The pericardium is like the armor of the heart. It is protected on the outside of the heart. It is a sac-like structure that surrounds the heart and the roots of the large blood vessels.
There is a cavity between the heart and the pericardium, called the pericardial cavity, which refers to the space between the parietal pericardium and the visceral pericardium on the surface of the heart.
There is a small amount of light yellow liquid in the normal pericardial cavity, which lubricates the surface of the heart. This is just like the engine. It has the function of a lubricating oil. After all, the heart beats the piston and constantly beats. The pale yellow liquid is lubricating oil, which reduces friction between the heart and the pericardium.
When a traumatic heart rupture or pericardial blood vessel damage ~ EbookFREE.me ~ can cause blood accumulation in the pericardial cavity called hemopericardium or pericardial tamponade, which is the cause of rapid death from cardiac trauma.
Due to the limited elasticity of the pericardium, acute pericardial hemorrhage can reach 150ml, which can limit blood return to the heart and heart beat, causing acute circulatory failure and then cardiac arrest.
After all, you think about it, blood accumulates in the pericardial cavity, and the heart can't beat. In order to provide the body with continuous blood supply, the heart can only shrink and dilate desperately. This causes the heartbeat to speed up, but the more blood it pumps out, Less and less, because the resistance from the pressure outside the heart is growing!
Soon, the heart may have a sudden cardiac arrest, leading to acute circulatory failure or even ... immediate death!
Therefore, the patients are in critical condition, very dangerous, and may face death anytime, anywhere.
Now, what we have to do is to relieve heart compression is the only frontline vitality for patients.
ps: There are four chapters later, and five chapters tonight.
