Because even if there is a small gap, when the pericardium contracts again, the blood will still be pressed out of the gap in the heart and will be squeezed into the chest cavity.
No one in the world has suffered a heart injury that can delay the death for so long, and no one can be sutured after the heart is injured.
Nangong Nuannuan has no experience to learn from. He can only try this operation for the first time with his own understanding of the structure of the human body-heart suture repair.
If this operation is really successful, she will break the argument that she will die after a heart injury.
Nangong Nuannuan’s stitching is very detailed. Although she can do this in less time, she is faced with Chiyang brother, so even if she knows whether she is fast or slow, the effect will not be much worse, but Nangong Nuannuan is still more cautious than usual sutures.
The wound at the heart is a bit big, but because the steel bar was tied down, the pericardium was wiped away and the pericardium was damaged, but I was glad that the atrium and ventricle were not hurt. So she only needs to sew up the damaged pericardium.
Two hours is a very long time for Nangong Nuan Nuan. In terms of her hand speed, she should be able to do such stitching in about half an hour.
But because this is Chiyang's brother, Nangong Nuan Nuan was very serious during the operation, which took two hours.
Two hours later, the repair and suturing of the pericardium were completed.
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, a visceral organ that is always squeezed by pacing, not to mention 0.5 cm, even a 0.01 cm damage will be fatal.
After the operation, Nangong Nuannuan put away more than 10 silver needles stuck in the heart.
After the silver needle was retracted, the myocardium, which had originally expanded to become incapable of contraction, began to contract for the first time.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 start again and again. In medicine, this is called blood circulation.
The main function of blood circulation is to use blood as a means of delivery, by absorbing nutrients drawn from food and fresh oxygen drawn from the lungs, the venous blood is converted into arterial blood, which is transported to various organs, tissues and cells of the body for its completion Important physiological functions. After the use of tissues or cells, the generated waste and exhaled carbon dioxide enter the blood and become venous blood, which is then carried through the blood to the lungs, liver, kidneys, skin and other organs and tissues to be discharged from the body to ensure the continuous metabolism of various parts of the body.
And 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 compressed for the first time only reached about 30 ml, and then began to rebound quickly.
After about a minute, each contraction can reach more than 70 milliliters of blood.
When I saw that the blood no longer leaked through the pericardium, but according to the guidelines of the heart, it circulated to the veins and to the brain, and the brain was supplied with fresh blood. Nangong Nuan Nuan finally exhaled.
The heaviest injury was finally fixed.
However, the ventilator cannot be disassembled.
