BXBX NOVEL Chapter 2479: 【2479】There is knowledge among them
turned around, Xie Wanying faced the assisting classmate Wei and said in a low voice, "She probably has a fractured pelvis. Be very careful when lifting and fix her pelvis."
Wei Shangquan was frightened as soon as he heard the word pelvic fracture.
Pelvic fractures, and those who have seen seriously injured people in car accidents will have a very deep impression of the most dangerous trauma. This is due to the fact that there are too many organs involved in and around the pelvis from an anatomical perspective. 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 pelvic fractures can be so severe that doctors usually have less than six hours to rescue and stop the bleeding.
After being frightened, Wei Shangquan observed the injured again: Hey, no shock?
"She may be a compression fracture, Tile type A, so there is no internal bleeding." Xie Wanying and her classmates whispered. These words should not be heard by the injured to avoid unnecessary panic of the injured.
The Young-Burgess classification is commonly used to classify pelvic fractures into four types, with the goal of distinguishing the severity of the injury and guiding the prognosis. According to this classification principle, the most serious of the four types is the front and rear extrusion type, also called the separation type. Separation mainly refers to the separation of the pubic symphysis. The separation of the pubic bone can easily cause the rupture of the ligaments that hold the pelvis. After such a series of chain reactions, severe bleeding is indispensable. Therefore, this type has the highest mortality rate.
The compression fracture mentioned by Xie 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 fractured pelvis, which is the Tile classification mentioned by Xie again. Tile classification is divided into A type B type C type. 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 and continued stability of the bone after a fracture.
As long as the bones can be basically maintained in place and stable, no roots are broken, no tips are exposed, and no nearby organs are injured, and no bleeding can be achieved, then rest and let the fractures grow slowly on their own.
The prerequisite for this step is to fix the pelvis, and never let the pelvis have a second disaster.
Why the common people understand that they cannot move around the wounded at the scene. Because you are not a professional, you cannot judge what the injured person is and how to move it. It is not that the injured person cannot be moved, but that the moving must follow the correct medical treatment path.
What injured person is the most difficult to move. If you have studied on-site pre-hospital first aid, you can know that it is the most difficult to judge and the most difficult to safely transport the injured and most likely to cause secondary injuries to the injured.
On-site emergency personnel need to take a deep breath, coordinate their thinking, and then take appropriate handling measures.
Wei Shangquan has a question: how did Xie determine that it was a pelvic fracture. You know, the injured person himself said that the left leg was suppressed, and the most serious injury should have been the left leg.
The injured person's left leg was under pressure, but when he pryed open the car board, only the skin was scraped, and there was no obvious swelling and bruising on the calf. On the contrary, when the injured person groaned when they shrank their legs, combined with the patient's awkward sitting position, it was clearly painful to sit and couldn't hold up, all of which could indicate that there may be a problem with the pelvis.
