Here we must first mention that the anatomical structure of the calf forearm is very different from that of the thigh upper arm.

The two positions of the lower leg and forearm are composed of two bones. The anatomical characteristics of the two bones are that the bones are connected by dense interosseous membranes, the fascia has low elasticity, and the fascial chamber has a small capacity. Therefore, there is no room for expansion after the limbs are compressed and swollen, unlike the loose tissues of the thigh and upper arm, which have a relatively large "tolerance" space.

To use an analogy, the tissues of the limbs can be simply understood as tables spliced ​​together. In the calf and forearm, the gap between the tables is small, and the tables are easily squeezed and broken when they are pressed. The situation of the thigh and upper arm is the opposite. The gap between the tables is large, and there is more space and time to withstand pressure.

The tissues in the calf and forearm have low pressure-bearing capacity, resulting in compartment syndrome that easily damages and kills nerves, muscles, and blood vessels. After muscle necrosis, a large amount of toxins are released into the patient's body, resulting in a high mortality rate among the injured.

The part where Liu Hui was under pressure was her forearm.

Since the collapsed object pressing on her forearm was difficult to remove, Grandma Cao, an orthopedic expert, first judged that compartment syndrome would occur sooner or later. Once compartment syndrome reaches the late stage, amputation is necessary to save her life. It is better to amputate at the beginning to save her.

In fact, even Zeng Wanning, who was a poor student, could tell at the scene that Liu Hui's hand could not be saved, because Liu Hui said that her hand had been pressed so hard that she had no feeling.

This is a symptom of the patient's limb nerves being damaged or killed.

The nerves are damaged or killed, and it is almost certain that the patient will enter the late stage of compartment syndrome.

...

The doctor on the scene made the assessment and immediately said: "Amputation."

Li Yongyi helped his classmates to shout on behalf of Liu Hui: "No, our teacher has waited for a long time and persisted for a long time just to avoid amputation, hurry up and send him to the hospital!"

These people left the medical staff on the scene completely speechless.

Zeng Wanning covered his head and tried to find a place to hide.

A group of students who were loyal to their teacher prevented the amputation from happening, so the doctor had to do his best to fulfill the patient's wish and send him to the hospital.

"How about sending you to the hospital?" Li Yong and others asked Zeng Wanning.

Zeng Wanning raised his face and shook his head: No, no, no! He would be scolded to death by his leader.

"Where else can we send you if not to the hospital?"

"Send it to Kong Yunbin. Teacher Liu has always trusted Kong Yunbin the most, and his grades are better than mine." Zeng Wanning suddenly had an idea and thought of another person to shift the blame to.

The ambulance carrying Liu Hui headed to the First Affiliated Hospital of Zhongshan Medical College.

The major newspapers and local TV stations, which had sufficient manpower, had already arranged for staff to wait in the emergency departments of major hospitals in the city. Among them, the emergency department of the First Affiliated Hospital of Zhongshan Medical College became a hot topic tonight. It was said that the two miraculous emergency surgeries reported on the scene were all performed by this hospital.

The First Affiliated Hospital of Zhongshan Medical College, which has been praised by countless people, actually has its own staff feeling a little guilty. They know that the surgeon and assistant who performed the two emergency surgeries were actually doctors from the Capital National Association, not their doctors.

The orthopedic surgeon who performed the first surgery on Jia was already very curious about the emergency surgeons on the scene, and he was sure that these doctors must be big shots. When Zhou Sheng's son was brought in, these doctors had to go to the emergency room to see patients anyway, so they quickly rushed down to see the real faces of the big shots.
