Chapter 2471 Suture Repair 2

Because even if that little gap is left, the next time the pericardium contracts again, 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 delay death for such a long time with a heart injury, and there is no one who can sew up after the heart is injured.

Nangong Nuannuan didn't have any experience to learn from. He could only try this kind of surgery for the first time-heart suture repair based on his sufficient understanding of the structure of the human body.

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 meticulous. Although she can use less time to do this, she is facing brother Chiyang, so even if she knows that whether she is fast or slow, the effect will not be much worse, but Nangong Nuannuan is still more careful than usual stitching.

The wound at the heart was a bit big, but when the steel bar was pulled down, it rubbed the pericardium and damaged the pericardium, but fortunately, the atrium and ventricle were not damaged. So she just needs to sew up the broken pericardium.

Two hours was a very long time for Nangong Nuannuan. Because with her hand speed, she should be able to do 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 sites were repaired, with the largest wound reaching a length of 3 cm and the smallest wound measuring 0.5 cm.

But such a heart is always squeezed by pacing, let alone 0.5 cm, even 0.01 cm of damage will be fatal.

After the operation, Nangong Nuannuan put away the 10 or so silver needles stuck in the heart.

After the silver needle was retracted, the myocardium, which had been expanded to the point of weak contraction, began to contract for the first time.

Each contraction of the heart will press out about 70 milliliters of blood, which will flow in a certain direction, over and over again. In medicine, this is called blood circulation.

The main function of blood circulation is to use blood as a carrier, by absorbing nutrients absorbed from food and fresh oxygen absorbed from the lungs, turning venous blood into arterial blood, and transporting 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 generated waste 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 through the blood, so as to ensure the continuous metabolism of various parts of the body.

The heart is the center that completes 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 it began to rise rapidly.

After about a minute, each contraction reaches about 70 milliliters of blood.

When he saw with his own eyes that the blood no longer leaked through the pericardium, but circulated to the veins and the brain according to the guidance of the heart, supplying the brain with fresh blood, Nangong Nuannuan finally exhaled.

The most serious injury was finally dealt with.

However, the ventilator cannot be removed.
