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 location range of the body surface, and some of it is in the ear.
.
A group of doctors at the scene could clearly understand that the danger mentioned by Xie was not nonsense as long as they associated the knowledge in relevant anatomy textbooks, and their speculations were in line with medical theory. The speculations she made might be almost 100% accurate. This is something they knew about her ability on the spot.
All my colleagues nodded inwardly and said: This situation is really bad.
This piece of glass fragment is like a sharp poisonous needle in a martial arts novel. The most obvious thing 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 cause infection if it falls into the human body. Importantly, as Xie pointed out, the location of a knife-like foreign body 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 arterial blood spurting out of their brains, they all looked pale and sweaty, making them want to vomit.
"What to do, doctor?"
"Do we need to operate on site 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 hard extraction okay? Think about Wu Lixuan’s case. Hard 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, and avoid causing greater damage, 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 cannot be done now.
Whether pre-hospital emergency surgery can be done depends on the situation. To put it simply, it depends on whether the conditions allow it. Some equipment is only available in the hospital operating room, and it cannot be done outside without this equipment. The cranial brain surgery mentioned before in the hospital,
To simply drill a hole and create a drainage tube, a surgical microscope is not needed.
At present, this injured person needs to open the skull to find foreign objects in the brain tissue, and what he needs is the assistance of a surgical microscope. No doctor's eyesight can reach the level of a microscope to replace a surgical microscope.
Everyone has high hopes for classmate Xie, can’t her eyesight replace the surgical microscope? She can guess the location of the injured internal carotid artery, and it seems that she can completely rely on her brain to direct her hands. Why can’t she replace the surgical microscope to operate the knife?
If I ask classmate Xie to tell me, she will tell me not to misunderstand.
For those surgeries she performed with her eyes closed, she actually opened her eyes occasionally to scan and remember the location of the nerves and blood vessels in the surgical field before proceeding. The brain did not collect the information in place, and she did not 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 predecessors, and then make a relatively accurate inferred diagnosis.
