   As long as the doctors at the scene think of the knowledge in the relevant anatomy textbooks, they clearly understand that what Xie said about the danger is not nonsense, and it is speculated that it is in line with medical theory. The speculation she made may be almost 100% accurate, and all the colleagues who knew her ability on the spot nodded in their hearts, and said: This is really bad.

   This piece of glass is like a sharp poison needle in a martial arts novel. The most obvious thing is physical damage. If the shard is contaminated with other substances, it may cause chemical damage.

  If it is not pulled out in time, it will cause infection when it falls into the human body. Important as Xie pointed out, the knife-like foreign body is located near the aorta, which is the most urgent solution in the current situation faced by patients and doctors.

   You can probably imagine the scene where a small knife cuts the aorta in your head.

  The doctor told the firefighters the risks of these patients in such simple and popular language.

   The firefighters were gasping for breath, and when their minds rolled over to the scene of arterial blood spurting in their brains, they were all pale and sweaty, making people want to vomit.

   "What shall we do, doctor?"

   "Are you going to perform an operation on the spot to pull out the fragments?"

  Many people have consulted the medical staff, begging the medical staff to save people quickly.

  How to save? For foreign bodies in the human body, the most straightforward solution a layman can think of is to pull them out.

   Is it okay to pull it hard? Thinking about Wu Lixuan\'s case, hard pulling is never recommended by doctors.

   To remove foreign objects, open the human body and take it slowly, so as not to damage the nerves and blood vessels and other important tissues inside, so as to avoid causing more damage, life-threatening or irreversible sequelae.

   Need emergency surgery.

   Emergency surgery in a non-hospital operating room has been mentioned before. For example, emergency brain surgery has been done before the hospital. It\'s just that this operation cannot be done now.

Whether    pre-hospital emergency surgery can be performed depends on the situation. To put it simply, it depends on whether the conditions allow or not. Some equipment is only available in the hospital operating room, and it cannot be done outside without this equipment. In the craniocerebral surgery performed by the hospital as mentioned before, a drainage tube is simply drilled and a surgical microscope is not used.

   At present, this wounded person needs to open the skull to find foreign objects in the brain tissue, and he needs the assistance of a surgical microscope. No doctor\'s eye sight is as good as a microscope to replace a surgical microscope.

   Xie, who has high expectations from everyone, can’t her eyesight replace a surgical microscope? She can infer the location of the injured internal carotid artery. It seems that she can rely on her brain to direct her hands. Why can\'t she replace the surgical microscope with a knife?

   Let Xie say it, she will say don\'t make any misunderstandings.

   For those surgeries that she performed with her eyes closed, she actually opened her eyes from time to time to scan and memorize the position of the nerves and blood vessels in the surgical field before continuing. The brain did not collect the information in place, and she dared not move the hand holding the scalpel.

   Specific to this case, the internal carotid artery is a large artery, and there are massive research data and summaries for reference. These allow her to observe the body surface mapping based on the value data provided by her predecessors, and then make a relatively accurate estimation and diagnosis.
