Because even if there is a small gap left, when the pericardium contracts again next time, blood will still be forced out of the gap in the heart and squeezed into the chest cavity.
There is no one in the world who can procrastinate for such a long time without dying of a heart injury, and no one can suture a heart injury after it is repaired.
Nangong Nuannuan didn't have any experience to learn from. He could only try such an operation for the first time based on his sufficient understanding of human body structure - heart suture repair.
If this operation is really successful, she will break the argument that after a heart injury, she will die.
Nangong Nuannuan's stitching is very meticulous. Although she can spend less time doing it, but she is facing brother Chiyang, so even if she knows that she is fast or slow, the effect will not be much worse, but Nangong Nuannuan is still more cautious than usual in sewing.
The wound on the heart was a bit big, but when the steel bar was tied down, it rubbed against the pericardium and damaged the pericardium, but thankfully it didn't hurt the atrium and ventricle. So she just needs to suture the damaged pericardium.
Two hours is a very long time for Nangong Nuannuan. Because with her hand speed, she should be able to finish this kind of stitching in about half an hour.
But because this is brother Chiyang, Nangong Nuannuan was very serious during the operation and it took a full two hours.
Two hours later, the pericardium was repaired and sutured.
A total of three places were repaired, the largest wound reached a length of 3 cm, and the smallest wound was 0.5 cm.
But the heart is an internal organ that is always squeezed by pacing, let alone a 0.5 cm, even a 0.01 cm damage will be fatal.
After the operation, Nangong Nuannuan put away the more than 10 silver needles stuck in the heart.
After the silver needle was put away, the myocardium, which had been enlarged to the point of being unable to contract, began to contract for the first time.
Each contraction of the heart will compress about 70 milliliters of blood, and the pressed blood will flow in a certain direction and go round and round. In medicine, this is called blood circulation.
The main function of blood circulation is to use blood as a vehicle to transform venous blood into arterial blood by absorbing nutrients absorbed from food and fresh oxygen absorbed from the lungs, and transport it to various organs, tissues and cells of the human body for its completion important physiological functions. After being utilized by tissues or cells, the waste produced and exhaled carbon dioxide enter the blood and become venous blood, which is then carried to the lungs, liver, kidneys, skin and other organs and tissues to be excreted from the body to ensure the continuous metabolism of all parts of the body.
The heart is the center of this huge circulatory system.
Because the myocardium was enlarged for 2 hours before, after the silver needle was withdrawn, the blood that was compressed for the first time only reached about 30 ml, and then began to rise rapidly.
After about one minute, each contraction can reach about 70 ml of blood.
Seeing with his own eyes that the blood no longer oozes through the pericardium, but circulates to the veins and brain according to the guidance of the heart, supplying the brain with fresh blood, Nangong Nuannuan finally exhaled.
The worst injury was finally healed.
However, the ventilator cannot be dismantled.
