Even if there was a small gap, the next time the pericardium contracted, blood would still be forced out of the gap in the heart and pushed into the chest cavity.
There was no one in the world who could survive for such a long time after suffering a heart injury, and no one could stitch it back together after suffering a heart injury.
Nangong Nuannuan did not have any experience to refer to. She could only rely on her understanding of the human body's structure to try this surgery for the first time — cardiac repair.
If this surgery was successful, she would shatter the myth that death was inevitable after a heart injury.
Nangong Nuannuan's suturing was very meticulous. Although she could do this in less time, she was facing Big Brother Chi Yang. So, even though she knew that no matter how fast or slow she was, the effect would not be much different, Nangong Nuannuan still sutured more carefully than usual.
The wound on the heart was a little big, but because the steel bar had grazed the pericardium when it was inserted, it damaged the pericardium. Fortunately, the atrium and ventricle were not injured. So, she only needed to suture the damaged pericardium.
Two hours was a very long time for Nangong Nuannuan. With her hand speed, she should be able to finish this kind of suture in about half an hour.
However, because this was Big Brother Chi Yang, Nangong Nuannuan was very serious during the surgery and spent a full two hours.
Two hours later, the repair and suture of the pericardium was completed.
A total of three areas were repaired. The largest wound was three centimeters long, and the smallest wound was five centimeters.
However, the heart was an internal organ that always depended on the pacing of the heart. Even a damage of 001 centimeters would be fatal, let alone five centimeters.
After the surgery was done, Nangong Nuannuan put away the more than ten silver needles in the heart.
After the silver needles were put away, the heart muscle, which had expanded to the point of being unable to contract, began to contract for the first time.
Each time the heart contracted, about 70 milliliters of blood would be squeezed out. The blood that was squeezed out would flow in a certain direction, repeating the cycle. In medicine, this was called blood circulation.
The main function of blood circulation was to use the blood as a means of transport. By absorbing nutrients absorbed from food and fresh oxygen absorbed from the lungs, the venous blood would become arterial blood and be transported to the various organs, tissues, and cells of the human body for them to complete important physiological functions. After being used by tissues or cells, the waste produced and exhaled carbon dioxide would enter the blood and become venous blood. Then, through the blood, it would be carried to the lungs, liver, kidney, skin, and other organs and tissues before being discharged from the body to ensure that the metabolism of the various parts of the body would continue.
The heart was the center of this huge circulatory system.
Because the myocardium had been expanded for two hours, after the silver needle was removed, the blood that was compressed for the first time only reached about 30 milliliters. After that, it began to recover rapidly.
After about a minute, each contraction could reach about 70 milliliters of blood.
Nangong Nuannuan finally let out a sigh of relief when she saw that the blood no longer seeped out through the pericardium. Instead, it followed the guidance of the heart and circulated to the veins, then to the brain, supplying the brain with fresh blood.
The most serious injury had finally been dealt with.
However, the ventilator could not be removed yet.
