Chapter 645: Replacement Surgery
Monday was not idle at home rest.
The quest continues to be brushed up.
A small heart repair surgery is not the ultimate goal of Zhou Yi.
Heart multi-valve replacement, or even a heart transplant, this level of heart surgery, is the ultimate goal of Monday.
Lying in bed on Monday, the rest of the day made him refreshed.
Supper on the table is also ready.
Close your eyes on Monday.
Began his third journey with an extra-mental dungeon.
[Cardiothoracic Surgery Intermediate (Director Level) Experience Career Copy].
The conditions for opening this quest are still high medical achievement points, which require 2000 points.
As a rule, if the completion rate reaches 60%, the medical point can be refunded in full.
Read Progress......
Realize the handover of the world and the virtual world......
Monday appears in the dungeon.
If the director-level copy is qualified from this copy, even if you don't use the auxiliary functions of the system, you will reach the level of Director Tian in the hard power last week.
So this copy didn't appear in the clinic on Monday.
With the foreshadowing of the previous copy, Zhou Yisheng, as an experienced old doctor, is already familiar with common heart diseases.
So the process of diagnosis is not necessary.
Go directly to the operating table.
As the white light in front of him dimmed, he found himself in an advanced laminar flow operating room when he could see his surroundings clearly.
In front of him, on the operating table, there is a patient lying down.
The anesthesiologist, itinerant nurse, and instrument nurse are all around.
There is no one help, two helps, only one main knife on Monday.
In addition to this, there is a well-dressed female doctor.
Although the female doctor was fully armed, Zhou Sheng could still see from her eyebrows and body shape that this was Lao He.
It seems that there is something wrong with her for a while, and she still teaches.
Just as Monday was still observing the situation in the operating room.
The patient's information has entered Monday's mind.
The patient is a male with severe mitral regurgitation who requires mitral valve replacement.
In the four valves of the heart. The mitral valve is located between the left atrium and the left ventricle.
The mitral valve acts as a "one-way flap" to ensure that blood circulation must flow from the left atrium to the left ventricle. When the left ventricle of the heart contracts, it squeezes the blood in the chamber and the blood hits the valves. The mitral valve closes and blood does not pour into the left atrium.
Mitral valve disease accounts for about 70% of valvular disease. However, it is an entry-level valve surgery.
Mitral valve replacement is a surgical procedure to replace a diseased heart valve with an artificial valve.
Changing parts for the heart looks pretty sci-fi.
But this surgery is not new.
As early as the late 40s of the twentieth century, there were studies on related aspects.
In 1960, American surgeon Starr and his collaborator Edwards first implanted an artificial spherical valve into a mitral valve patient with mitral valve stenosis.
It can be seen that this kind of surgery has a long history in heart surgery. In many places, the mortality rate for valve replacement is even lower than for major abdominal surgery.
Since you want to replace the valve, you need an artificial valve.
Prosthetic valves have also undergone nearly six decades of development.
The current technology is quite mature.
Monday is a type of mechanical flap used in the copy. A type of valve with hard metal as the main material.
The surgery began immediately.
The first is, of course, anesthesia.
Major cardiac surgery, which requires endotracheal intubation to assist breathing.
Intravenous compound fentanyl anesthesia.
Give GIK solution to protect the myocardium before starting.
End of anesthesia induction.
Monday on Monday.
Surgical approach, without the help of the auxiliary system, Zhou Zhou chose the most secure thoracotomy approach, the median sternum incision.
And then there's the general operation.
Skin incision, subcutaneous tissue incision.
The skin incision is slightly peeled to the right to expose the midline of the sternum.
Haemorrhage!
Hemostasis!
The sternum is also treated due to the median sternal incision.
After hemostasis is complete, the xiphoid process is excised, and the periosteal is cut with an electric knife along the midline of the sternum......
The sternum is split longitudinally along the midline from bottom to top with a windsaw......
The process of thoracotomy is very skillful in the operation of the week.
There was no problem, and Lao He didn't play any role on the side.
The next step is to deal with the heart.
First of all, as with cardiac repair, the pericardium outside the heart is still opened.
This process is in the second copy, and Zhou Yi has already practiced it perfectly.
In reality, I just got started once.
Naturally, there are no problems.
Lao He was on the side, and there was no reaction.
Open the pericardium.
Atrial and ventricular exposure.
All that's left is to replace the mitral valve.
At this time, Monday began to rust away.
But don't worry, Lao He spoke on the side, "The pericardium hangs over the skin, causing the right edge of the heart to rotate forward. ”
Monday did so quickly.
Suspend the pericardium.
Lao He continued to command: "Establish cardiopulmonary bypass!"
The process is more complicated.
After Lao He finished speaking, Zhou Zhou suddenly couldn't move.
Then Lao He stepped forward to demonstrate the operation.
Zhou Yi could only watch quietly.
By the time the demonstration was over, time seemed to have turned back.
The point in time is back to Monday, and I just finished the pericardial suspension.
Lao He's order was issued again, "Establish extracorporeal bypass!"
Monday understood that just now the system thought that he had not operated it.
Let's do a demonstration for yourself.
With the previous demo, Monday will start the operation.
The patient's heart is intubated to establish cardiopulmonary bypass.
The reason for the establishment of cardiopulmonary bypass is to wait a minute, to cool down the heart and stop beating.
Open-vision surgery in the heart requires a calm and bloodless field of surgery, so it is necessary to block blood circulation and temporarily stop the heart from beating next Monday. This will allow the heart to be replaced with a prosthetic valve.
Cardiopulmonary bypass is established.
All that remains is to cut the valve, replace the valve, and suture the prosthetic valve.
Of course, this process has to be demonstrated by Lao He himself.
Monday was like watching a movie, watching it on the side.
Demo over.
Time goes backwards, and Zhou Zhou draws a scoop on a gourd.
Use a retractor to expose the mitral valve......
Cut the mitral valve with scissors......
Zhou Zhou cut a little more, and Lao He immediately reminded: "Cutting too much will damage the left ventricular wall." 5% deduction for completion. ”
With Lao He's words.
Turn back the clock again.
On Monday, the mitral valve was cut again.
……
In the future, as long as there is a little mistake in the operation.
The operation will be repeated.
Of course, points will also be deducted for completion.
Monday had to go the extra mile.
……
Operate it down.
The mitral valve was finally replaced.
The whole operation took more than 4 hours.
Monday was so-so, barely passing.
This operation deducted 30% of the completion.
Fortunately, after the successful completion of the operation, a 20% completion reward was given, which gave Zhou Zhou a little hope.
This was only the first surgery that Monday experienced on Monday.
The copy of Monday is still ongoing......
