Say it here,
The difference between X-ray and CT.
As a simple example, we now observe the shape of an apple.
The naked eye can see the apple grows like this, only the appearance of the apple can be seen, not the inside.
·X film:
Looking at an apple is like taking a picture of an apple flat. You can only see one photo, and there is no way to distinguish the front and back.
With more details, it looks even more messy.
·CT:
CT is like cutting the apple section by section to see what is in each cross section and where there is an abnormality in each corner.
Then came out dozens of hundreds of pictures, each of which clearly reflects what is on each layer.
This is not enough. Three-dimensional reconstruction is needed to combine all the photos to get a three-dimensional image.
This will make it clearer whether there are bugs in the apple, where and how long…
…
The CT teacher was operating the CT machine, sweeping “one zero three” layer by layer.
The look is serious.
“I have seen a lot of hemorrhage, and I was doing the temporal lobe position. When a large amount of blood accumulates in the ventricle, it is usually high-density casting, and the intracranial pressure increases, the ventricle expands… there is a brain herniation…”
The same as Lin Feng’s judgment.
Lin Feng: “How much bleeding is there?”
CT teacher: “About 80 ml…”
Lin Feng turned to the emergency doctor: “Are you prepared for mannitol?”
Emergency doctor: “Yes!”
Lin Feng: “Immediately drip mannitol…”
at this time,
Lin Feng began to command.
The doctor in the emergency department is an attending physician, but he subconsciously follows Lin Feng’s instructions.
In fact, Lin Feng’s surgeries formed over the years have a very strong control aura, and people can’t help but listen.
…
Next, it is how to treat.
Lin Feng: “The bleeding volume of the patient is not small, so the emptying operation should be carried out as soon as possible, otherwise it may cause serious consequences such as necrosis of the space-occupying brain tissue, and there is a high probability of direct brain death…”
Attending physician Wang Hua: “Our brain surgery has 2 testing instruments, which can perform brain emptying operations…”
Lin Feng: “Ask about brain surgery, how long will it take to perform this operation?”
Wang Hua nodded: “Okay, I’ll call and ask…”
Make a call on the spot.
soon,
The Department of Brain Surgery responded.
“Surgery preparation time is 1 hour…”
Lin Feng immediately shook his head: “It’s too slow, no… the patient has a lot of bleeding, and the patient will die directly…”
Attending Wang Hua: “Dr. Lin, do you mean empty-handed drainage?”
Lin Feng nodded: “Yes, it’s empty-handed drainage.”
Wang Hua frowned: “This operation…our emergency department is probably no one can do it. Major doctors usually arrange it very well…”
Lin Feng: “It’s okay, I’ll do it…”
Wang Hua worried: “This is too dangerous…”
Lin Feng shook his head, firmly: “It is because of danger, so I will do it…”
The attending doctor is a bit embarrassed.
Because Lin Feng does not belong to the Ditan Hospital, although he can operate in compliance with the law, he is afraid of upsetting the leadership. After all, Lin Feng belongs to Harmony Hospital.
He consulted the director of the emergency department.
The director of the emergency department and two doctors soon came to the CT room.
“Lin Feng…”
“Ah… Teacher Chen?!”
Lin Feng was surprised to find that the director of the emergency department turned out to be one of the teachers of Lin Feng’s graduate program.
Acquainted.
The other two doctors greeted Lin Feng when they saw Lin Feng.
“Doctor Lin!”
“Doctor Lin!”
Lin Feng: “Hello…”
Then introduced the condition…
One by one doctors showed embarrassment.
They can’t deal with this patient!
At this time, the attending doctor of brain surgery came and consulted.
It also showed embarrassment.
“Empty-handed drainage surgery can only be performed at the deputy director and above (in fact, it is very difficult and risky), but every doctor at the deputy director and above is very tight in scheduling, I am afraid it is a bit difficult…”
Lin Feng: “It’s okay, let me come…”
Director Chen nodded: “Okay, Lin Feng, you come to arrange…whatever, you just need to order…”
Lin Feng: “The operation will be arranged directly in the CT room…”
The CT room was occupied like this.
10 minutes later,
Everything, according to Lin Feng’s instructions, is ready.
…
Lin Feng took over the patient,
Official rescue begins!
The operation begins! !
first step,
Shaving…
Use CT to measure the length to determine the depth of the puncture drainage tube: (the length of the hematoma + the length of the puncture point from the front of the hematoma)
After determining the location of the drill hole,
Start to position the patient (side position).
The second step,
Routine disinfection, spreading and local infiltration anesthetize the scalp puncture point…
Start drilling…
Three holes were drilled into the skull (within the hematoma cavity)…
Then a series of complicated needle operations…
Push the drainage tube to the calculated puncture depth, and then pull out the needle core…
Then insert a 10ml syringe to slowly suck the hematoma…
When the red blood is continuously drawn out little by little and enters the syringe,
The doctors and nurses in the entire CT room, Qi Qi breathed a sigh of relief 0 ……..
This step,
It shows that the depth is correct and the puncture is successful.
Basically heralded that the entire operation was almost a success!
Next,
Lin Feng patiently took out about 30%-40% of the total hematoma, and then slowly injected a small amount of saline to flush the hematoma cavity…
The purpose of this is to eliminate strong negative pressure suction.
Repeated several times,
The position of the drainage tube was adjusted in the middle.
In 10 minutes, all the hematomas were finally sucked out.
Check the total drainage volume. If the amount of hematoma calculated by the preoperative CT scan is almost the same, the operation is almost complete.
Then inject urokinase and normal saline into the hematoma cavity…
After doing this,
Lin Feng breathed a sigh of relief…
“It’s okay. After closing the tube for half an hour, let go of the drainage and take out the saline… Then check for bleeding. If there is no bleeding, the operation was successful…”
Director Chen patted Lin Feng on the shoulder and gave a thumbs up.
Other doctors and nurses admire them very much.
“Doctor Lin, awesome!!”
(The drainage tube can only be unplugged after 2.3 at least a few days…)
…
CT operating room,
A few off-duty nurses hid behind the door,
“Did Dr. Lin come out?”
“It seems to be still undergoing surgery…”
“I heard that it was empty-handed drainage. Many doctors can’t do it…”
“Look… the door is open… Wow, Doctor Lin is out!”
“Wow, so handsome!”
“Take a photo, take a photo!”
“Director Chen of the emergency department seems to be familiar with Dr. Lin Feng? With a smile on his face, it should be a successful operation, right?”
“The operation was successful…”
“The successful man is the most handsome!”
That night, the news spread to the entire Ditan Hospital as if it was windy.
The handsome photos spread all over the Ditan Hospital.
The success of a difficult operation has also spread to Ditan Hospital.
