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.
.As long as the doctors at the scene associate the knowledge in relevant anatomy textbooks, they will clearly understand that the dangers mentioned by Xie are not nonsense, and their speculations are in line with medical theory. Her speculations may be almost 100% accurate.
, all the colleagues who knew her abilities at the scene nodded inwardly and said: This situation is really bad.
This piece of 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 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 blood spurting from the arteries in their brains, they all looked pale and sweating, making them want to vomit.
"What should we 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 body, open the human body and take it out slowly so as not to damage the important tissues such as nerves and blood vessels inside, and avoid causing greater damage, life-threatening or irreparable sequelae.
Emergency surgery is needed.
There have been many cases of emergency surgery performed in non-hospital operating rooms before. For example, emergency brain surgery was performed before the hospital. 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 permit or not. Some equipment is only available in the operating room of the hospital. It cannot be done outside without this equipment. The craniocerebral surgery mentioned before is done in the hospital.
The surgery involves simply drilling a hole to create a drainage tube, and does not require a surgical microscope.
The injured person currently needs to open the skull and find foreign objects in the brain tissue. 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. Classmate Xie, who everyone has high hopes for, can't her eyesight be enough?
Can it replace the surgical microscope? She can guess the position of the internal carotid artery of the injured person. It seems that she can completely rely on her brain to direct her hands. How can it not replace the surgical microscope?
Use the knife?
If I ask classmate Xie to tell me, she will tell me not to misunderstand.
For those 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. The brain did not collect the information in place, and she did not dare to move the hand holding the scalpel. Specifically, this
In the 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.
