Xie Wanying believes that there is no need to say these words herself, Zhang Wei, who has experienced what she has experienced today, will figure it out on her own.
Turning around, Xie Wanying faced the assisting classmate Wei and whispered: "She probably has a pelvic fracture. You need to be very careful when lifting her to fix her pelvis."
Wei Shangquan was frightened whenever he heard the words pelvic fracture.
Pelvic fractures, those who have seen severely injured people in car accidents in clinical settings will have a very deep impression of the most dangerous trauma. This is because from an anatomical point of view, there are too many organs involved in and around the pelvis. As long as the tip of the fracture end is exposed, it is easy to
Puncture the organs in or near the pelvis, causing hemorrhagic shock. Such a severely injured pelvic fracture will usually leave less than six hours for doctors to rescue and stop bleeding.
After being frightened, Wei Shangquan looked at the injured again: Hey, isn't he in shock?
"She may have a compression fracture, Tile classification type A, so there is no internal bleeding yet." Xie Wanying communicated with her classmates in a low voice. These words should not be heard by the injured to avoid unnecessary panic.
The commonly used Young-Burgess classification of pelvic fractures is divided into four types. The goal is to distinguish the severity of the injury and guide the prognosis. According to this classification principle, the most serious of the four types is the front-to-back compression type, also called separation type. The separation type is mainly
It refers to the separation of the pubic symphysis. The separation of the pubic bone can easily lead to the rupture of the ligaments that maintain the pelvis. Such a chain reaction will lead to severe bleeding. Therefore, this type has the highest mortality rate.
The compression fracture that Xie mentioned is the lateral compression fracture, which is the most common type of pelvic fractures, accounting for half of the total number, and has a lower mortality rate than separation fractures.
What type is the best? Here I would like to propose another classification of fractured pelvis. The Tile classification method mentioned by Xie. The Tile classification method is divided into type A, type B, and type C. This classification method is based on the occurrence of fractures.
After the fracture, the bone is classified according to whether it is displaced, stable or unstable. Type A is undoubtedly the best, as it moves slightly and the bone continues to remain stable after the fracture.
As long as the bone can basically remain stable in its original position, with no roots broken, no tip exposed, no damage to nearby organs, and no bleeding, then rest and allow the fracture to grow back on its own.
The prerequisite for achieving this step is to fix the pelvis well to prevent a second disaster from happening to the pelvis.
Why do ordinary people know that you should not move the injured at the scene? Because you are not a professional, you cannot judge the condition of the injured and how to move it. It is not that the injured cannot be moved, but that the move must follow correct medical principles
Processing paths.
Which injured person is the most difficult to move? If you have studied on-site pre-hospital first aid, you will know that the most difficult to judge, the most difficult to safely move the injured, and the most likely to cause secondary injuries to the injured are the injured with various fractures.
On-site first responders need to take a deep breath, coordinate their thinking, and then take appropriate handling measures.
Regarding this, classmate Wei Shangquan had a question: How did classmate Xie determine that the pelvis was fractured? You must know that the injured person said that his 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 pried open the car panel, he found only scratched skin and no obvious swelling or bruises on the calf. Instead, the injured person moaned when he retracted his leg. Combined with the patient's awkward sitting posture, it was obvious that he was in pain when sitting.
If you can't hold it up, these can indicate that there may be a problem with the pelvis.
