Chapter 1830： Machine 1 precision
Open the sternum, quickly stop the blood, expose the surgical field, Zheng Ren is now as expected, the internal adhesion is very heavy.
The second operation is like this. After a single operation, the human body will have fibrous connective tissue hyperplasia and change the normal physiological anatomy.
Looking at the messy tissue inside, Zhao Yunlong had some headaches.
The elephant nose surgery itself is the largest surgery in cardiothoracic surgery, and the second phase of the nose surgery...
1o difficulty!
Zheng Ren reached out and stopped the hemostatic forceps and blunt scissors in his hand.
Lao He glanced at it and felt that it would take at least a few minutes to open the aorta. This is still the boss of Zheng. If you change someone else, it will take at least 3o-6o minutes to clear the aortic arch.
He took out the u disk, quickly found the audio file, and opened the good luck song.
The familiar and melodious music sounded, but this time Su Yun did not complain. He did not seem to hear that the background music had been switched. He concentrated on Zheng Ren’s dissociation.
Two hemostatic pliers flew up and down, and it was beautiful.
The blunt scissors are free, and the squeaking sound of the vocal knife sounds.
"Prepare for heparinization." Zheng Ren is free and sighs.
Lao He was a little surprised and surprised at the confidence of Zheng Boss. Heparinization does not take long, and heparinization is usually performed after the surgery area is prepared.
And Zheng Boss has confidence in his freedom, estimating the time, and heparinization is needed in the morning.
Lao He began to prepare calmly while paying attention to the operation.
After 312", the aortic arch is completely present in the field.
The aortic arch and its branches are freed and banded separately.
"Heparinization is complete."
In the moment when Zheng Ren just took the band, Lao He said.
Time is just right, Lao He knows that it is not a good match for himself, but that Zheng Bo has an extremely accurate assessment of his own level.
If the medical team is a machine, it is just a component. The level of high and low, has long been touched by Zheng boss, calculated into the process of surgery.
Looking at the seamlessness of the match is actually the embodiment of Zheng’s computing power. Lao He just sighed, but did not continue to think.
The operation is still going on, and he is not allowed to distract him.
After heparinization, Zheng Ren inserted the 24f artery cannula into the right subclavian artery 2 to 3 cm. This side does not dare to insert too deep, because the intubation is too deep to enter the unknown artery and seriously affect the cerebral perfusion.
Then insert the right chamber lumen or the superior and inferior vena cava cannula.
“Full flow turns to cool down.”
Only one person in the operating room spoke, and the quiet operating room atmosphere proved the difficulty of the operation from the side.
Oxygenated blood was supplied to the whole body from the right subclavian artery through the innominate artery to the aorta, and the right ventricle was inserted into the coronary sinus retrograde perfusion tube.
"Report the nasopharyngeal temperature."
";" ";"; When the nasopharyngeal temperature drops to 26 ~ 28c, the ascending aorta is blocked, and the cold blood cardioplegia is retrogradely perfused through the coronary sinus.
While continuing to cool down, the patient completed the lesion exploration, prosthetic valve replacement, proximal cardiac vascular anastomosis, coronary artery anastomosis and coronary artery anastomosis.
Zheng Ren moves quickly, but the more he probes, Su Yun’s heart... a little panic.
Ma Fang Syndrome is a congenital disease. After 2 years of ascending aortic valve replacement and coronary artery transplantation, the patient's local changes are large, and the original prediction is made.
The adhesion is very heavy, let alone mention this. A bubble sign appears faintly in the middle section of the anastomosis segment, meaning the possibility of a mezzanine afterwards.
Do you have to do the surgery in the same period?
Even Su Yun is caught off guard by this situation and has some headaches.
When he saw the situation in the operation area, he looked up at Zheng Ren.
Zheng Ren seems to have no emotional changes at all, and he is doing surgery without fear.
Su Yun’s heart is faintly a little bit solid, and there are bosses who are afraid of it.
"22c." Lao He continued to report the temperature.
"2o °." Zheng Rendao.
The values said by the two are completely different concepts. The old congratulatory report is the key point of the nasopharyngeal temperature, which must be paid attention to during deep hypothermic circulatory surgery.
The 2o° that Zheng Ren said is the angle of the patient's head. After Zheng Ren finished, the three stopped the operation at the same time, and Lao He began to adjust the angle of the operating table.
The head side is down, at an angle of 2o.
Zheng Ren then blocked the innominate artery, the left common carotid artery and the left subclavian artery in turn, reduced the arterial flow to 8m1/kg·min, continued selective cerebral perfusion, and opened the ascending aortic occlusion forceps to start the aortic arch. Department and bow lowering surgery.
"2oc." Lao He is still reporting the temperature with dedication.
This temperature is the horn of the general attack.
After the end of the old heat, Zheng Ren immediately blocked the ascending aorta, and the heart of the aorta was cold-fed and stopped.
"Ice mud."
The prepared ice mud was sent to Zheng Ren's hand.
Zheng Ren first tried it, there was ice and water, 4 degrees Celsius. There are no large pieces of ice, all of which are small pieces of ice, which can cool the heart as quickly as possible.
General heart surgery can make this perfect ice mud, at least a few percent increase in surgical completion.
This is a detail but it is an indispensable detail.
Zheng Ren is very satisfied, and the surface of the heart is cooled by ice.
The nasopharyngeal temperature dropped to 18c, Zheng Ren began to block the 3 branches of the aortic arch, and the extracorporeal circulation arterial perfusion flow was changed to 6m1/(kg·min) for selective antegrade cerebral perfusion.
The aortic arch was cut along the long axis of the aortic arch, proximal to the original vascular anastomosis, and distal to the proximal end of the left subclavian vein.
Because the heart stops, deep hypothermic cardiopulmonary bypass has been established, so when the aortic arch is open, there is no blood flow.
The clean aortic arch is clear.
The purpose of deep hypothermic circulatory surgery is for this moment, and at this time it seems almost perfect.
"Attention to the amount of blood clots in the brain." Zheng Ren cut open the aortic arch, and said in a deep voice: "If you are unfamiliar with Lao He, bring the screen side to 22 °, I look at it."
Lao He is a bit shy, this should have been the work of an anesthesiologist.
But under the operation, or the new machine just in contact, how can I get to know, understand, and run in.
He did not hesitate to do what Zheng said, and the sound probe was placed on the patient's neck, which did not affect the position of the operation and the head. And the screen side to Zheng Bo, the countless data above is fluttering.
The amount of data is so large that Lao He is helpless.
This should be a laboratory product, or an initial one, and there must be computer precision calculations to output the results.
But now there is no end result, only to see the countless data signals on the screen appear like snowflakes.
From time to time, Zheng Ren looked up at the screen of the color Doppler sound, but the movements in his hand did not stop.
