2479 Chapter 2479 [2479]

Xie Wanying believes that there is no need to say these words by herself, Zhang Wei, who has experienced what happened today, will figure it out by herself.

Turning around, Xie Wanying whispered to classmate Wei who was assisting her: "She probably has a broken pelvis, so be very careful when lifting, and fix her pelvis."

As soon as Wei Shangquan heard the words pelvic fracture, he was frightened.

Pelvic fractures, those who have seen severe injuries in car accidents clinically will be very deeply impressed by the most dangerous trauma. This is due to the anatomy of too many organs involved in and around the pelvis. As long as the pointed end of the fracture is exposed, it is easy to puncture the organs in or near the pelvis, causing hemorrhagic shock. Such a seriously injured pelvic fracture will be so severe that it usually takes less than six hours for the doctor to rescue and stop the bleeding.

After being frightened, Wei Shangquan observed the injured again: Hey, no shock?

"She may have a compression fracture, type A of Tile classification, so there is no internal bleeding yet." Xie Wanying communicated with her classmates in a low voice. These words cannot be heard by the injured, so as to avoid unnecessary panic for the injured.

Pelvic fractures are commonly classified into four types by the Young-Burgess classification, with the goal of distinguishing the severity of the injured and guiding the prognosis. According to this classification principle, the most serious of the four types is the front and rear extrusion type, also known as the separation type. The separation type mainly refers to the separation of the pubic symphysis. Separation of the pubic bone can easily cause rupture of the ligaments that maintain the pelvis. After such a series of chain reactions, severe bleeding is inevitable. Therefore, this type has the highest mortality rate.

The compression fracture that Xie mentioned is the lateral compression type, which is the most common type of pelvic fracture, accounting for half of the total, and the mortality rate is lower than that of the separation type.

What is the best type, here is another classification of the fractured pelvis, which is the Tile classification method that Xie mentioned again. The Tile classification is divided into Type A, Type B, and Type C. This classification method is based on whether the bone is displaced, stable or unstable after the fracture occurs. Type A is undoubtedly the best, with slight movement, the bone continues to remain stable after the fracture.

As long as the bones can be basically maintained in place and stable, with no broken roots, no exposed tips, no damage to nearby organs, and no bleeding, rest rest and allow the fractures to heal slowly by themselves.

The prerequisite for this step is to fix the pelvis and absolutely prevent the pelvis from having a second disaster.

Why the common people understand that the wounded at the scene should not be tampered with. Because you are not a professional, you cannot judge the condition of the injured person and how to move it. It is not that the injured cannot be moved, but that the movement must follow the correct medical treatment path.

The wounded are the most difficult to move. If you have studied on-site pre-hospital first aid, you can know that the most difficult to judge, the most difficult to safely transport the injured, and the most likely to cause secondary injuries to the injured are all kinds of fracture injuries.

The on-site emergency personnel need to take a deep breath, coordinate their thinking and then take appropriate handling measures.

Wei Shangquan has a question about this: How did Xie determine that it was a pelvic fracture. You should know that the injured person himself said that his left leg was pinned, and the most serious injury should have been on his left leg.

The injured man's left leg was under pressure, but when he opened the car panel, he saw that the skin was scratched, and there was no obvious swelling and bruising on the calf. On the contrary, when the injured person withdraws his legs, he groans, combined with the fact that the patient's sitting posture is awkward and obviously hurts while sitting, these can all indicate that there may be a problem with the pelvis.
