I couldn't remember what the knowledge point she said. Fortunately, he was also a top student and was smart. He knew that he was following classmate Xie and asked, "What do you mean?"

As he asked, his face turned a little blushing. He must have remembered the days when he had laughed at Geng Lingfei and said that he was an idiot after following Xie, but now he became an idiot.

"Don't close your chest when the operation is over." Xie Wanying is a modest person. She doesn't pretend to be noble and ignores her classmates. She will answer within the scope of time when she has time to answer.

At this moment, Dai Nanhui was suddenly moved.

The two ran to the next ward.

Xiaohui, lying on the snow-white bed sheet, had a snow-white face, a ventilator with a tracheal tube on her throat, and other machine pipes connected to other parts of her body were like a broken doll that supported her life with only a machine, which made people heartbreaking to look at.

Xie Wanying's hand carefully lifted the child's quilt and exposed the child's chest.

Seeing the transparent dressing on the child's chest, Dai Nanhui finally remembered the relevant knowledge point: "It's not the sternum."

Delaying the chest closure, as Student Xie said, the surgeon did not close the chest cavity to the patient according to the routine surgical procedures at the end of the operation. The most important step to close the chest cavity is to close the sternum.

Why don’t the doctor turn on the sternum?

Most of the time the doctor doesn’t turn it off because it is found that the chest cavity cannot be turned off after the operation.

It's so strange? Can the sternum be pulled up? Can it be pulled up even if it is deadlifted?

To be precise, if the chest cavity is closed, the patient's life will be lost, so it cannot be closed. This situation is specifically reflected in that after closing the sternum, the heart may be compressed and caused a heart crisis. The bleeding of the heart may not only require the chest gauze to be opened to compress and stop bleeding. How to close it? The pericardial filling may also require the chest to be opened and drained.

What are the benefits of not closing the central sternum incision to open the sternum? It can expand the volume of the patient's mediastinum and reduce the compression of the heart mainly involves external pressure on the ventricular wall, while increasing the volume at the end of the diastolic period of the heart. All of this is conducive to stabilizing the patient's blood circulation and breathing.

Delaying the chest closure does not mean that it is not really about the patient's sternum. It is just waiting for the patient's critical situation to pass before closing the sternum.

What should I do if I don’t care about the sternum and open the exposed heart? Doctors may sew the outside skin together. Given this critical phenomenon that patients may need to be rescued at any time, many doctors now choose to cover only a layer of disinfectant and transparent surgical film to protect the wound.

If you look close, you can see through the transparent membrane that is not in place, and you can open the sternum with a sternum expansion device.

What should I do in this situation? Do I do heart compression and defibrillation in my chest? Dai Nanhui's mind turned to this, and suddenly I saw Xie Wanying in front of me taking action. He was worried and shouted, "What do you want to do?"

Xie Wanying's eyes locked on the electrocardiogram data on the ECG screen of the ECG monitor, and then rushed to the rescue vehicle prepared by the nurse in the corner of the ward as quickly as possible. She grabbed the sterile gloves placed on the upper layer and teared the outer packaging, and put on the gloves skillfully.

"Do you want to do a heart pressure on her inside her chest?" Dai Nanhui was frightened and shouted anxiously when she felt that she might have to do this with gloves.
