The direction of the internal carotid artery has been roughly discussed in Dr. Hu's case before. It originates from the common carotid artery and branches to the important ophthalmic artery. It can be imagined that it maps to the anatomical position range of the body surface, and some of them are in the ear. As long as the doctors at the scene recalled the knowledge in relevant anatomy textbooks, they clearly understood that the dangers mentioned by Xie were not nonsense, and their speculations were in line with medical theory. The guess she made might be almost 100% accurate.
, all the colleagues who knew her ability at the scene nodded inwardly, saying: This situation is really bad.
This glass fragment is like a sharp poisonous needle in martial arts. The most obvious damage is physical damage. If the fragment is contaminated with other substances, it may cause chemical damage.
If it is not pulled out in time, it will fall into the human body and cause infection. Importantly, as Xie pointed out, the knife-like foreign body located near the aorta is the most urgent situation faced by patients and doctors.
You may be able to imagine what it would be like to cut a large artery in your head with a knife.
The doctor used such simple and popular language to tell the firefighters about the risks of these patients.
The firefighters gasped and gasped. When their minds turned to the scene of blood spurting from the arteries in their brains, they all looked pale and sweating, making people want to vomit.
"What to do, doctor?"
"Do we need to perform an on-site operation to pull out the fragments now?"
Many people consulted medical staff and begged them to save people quickly.
How to save? When a foreign object is in the human body, the most straightforward solution a layman can think of is: pull it out.
Is it possible to pull it out by force? Thinking about Wu Lixuan's case, forced extraction is never recommended by doctors.
When removing a foreign object, open the human body and take it out slowly, so as not to damage the nerves, blood vessels and other important tissues inside, so as to avoid causing greater harm, life-threatening or irreparable sequelae.
Emergency surgery is needed.
There have been many cases of emergency surgeries performed in non-hospital operating rooms before. For example, emergency brain surgeries were performed in pre-hospital settings. However, this surgery is not possible today. Whether pre-hospital emergency surgery can be performed depends on the situation. To put it simply, it depends on whether the conditions allow it. Some equipment is only available in hospital operating rooms. It cannot be done outside without this equipment. The cranial surgery done in the hospital as mentioned before
The operation involves simply drilling a hole to create a drainage tube, and does not require a surgical microscope.
The injured person currently needs the help of a surgical microscope to open his skull and find foreign objects in the brain tissue. No doctor's eyesight can reach the level of a microscope to replace a surgical microscope. Classmate Xie, whom everyone has high hopes for, can’t her eyesight replace a surgical microscope? She can guess the location of the injured person's internal carotid artery. It seems that she can completely rely on her brain to direct her hands. Why can't she replace the surgical microscope?
Use the knife?
If I ask Student Xie to tell me, she will tell me not to misunderstand.
For surgeries that she performed with her eyes closed, she actually opened her eyes from time to time to scan and remember the location of the nerves and blood vessels in the surgical field before proceeding. Her brain didn't have enough information to collect, and she didn't dare to move the hand holding the scalpel. Specific to this case, the internal carotid artery is a large artery, and its direction and location have a large amount of research data and summaries for reference. These allow her to observe the body surface mapping based on the valuable data provided by her predecessors, and then make a relatively accurate diagnosis. .
