Bed 18 had surgery today.

In neurosurgery, the most learned thing is positioning and repositioning. Only accurate positioning can minimize intraoperative injury and avoid postoperative sequelae.

As mentioned in the previous operation, before the operation, the 18th bed will be sent to the MRI room for positioning and then come back, using a three-dimensional navigation system. For this type of surgery, it is not enough to use only the navigation system. In order to avoid the image drift mentioned last time, the doctor will use a special method to locate during the operation.

It is not the ultrasound mentioned last time, but the electrophysiological positioning. When it comes to electrophysiological localization, we can quickly think of the localization problem encountered by Mr. Wei when he performed interventional ablation surgery last time, and he also used electrophysiological localization. Therefore, the principle of radiofrequency destruction of neurosurgery is similar to that of cardiac interventional ablation. The same is after positioning, put the electrode into the electrocautery target.

Unlike previous examinations, electrophysiological localization is interfered by other factors during the passage of time. It is a real-time examination with higher accuracy.

In this way, is it possible to skip other preoperative examinations? no.

This is the case in medicine. It is best that the various examinations can be based on each other to pursue the highest diagnostic accuracy. This is to follow the evidence-based rules of each scientific discipline. It's just an isolated inspection result for fear of making mistakes. The instrument is not 100% error-free, and the instrument will also be affected by some unknown factors.

Therefore, doctors need to be as step-by-step as possible, follow the diagnosis and treatment norms, and insist on completing every necessary examination for the patient. Even if some family members and patients don't understand and complain about too many inspections.

In neurosurgery, the positioning of such an important department requires inspections to be done accurately to ensure that the doctor's judgment during the operation is correct.

For this reason, before the operation began, the medical staff was very busy. The busiest one was the young doctor, who went back and forth to collect all the errands. Then send the patient to the MRI CT room, and then send the patient directly to the operating room after returning.

In the operating room, senior doctors will give young doctors the opportunity to practice properly and put patients on the top.

This time it was a metal headgear, a bit heavy, like a globe, and the ball in the middle became the patient's head. As I introduced last time, measure with several rulers on the head frame, and measure continuously.

Measure again, check the navigation system against the benchmark, read it again, and discuss it again. An hour passed. Finally, it is time to finally determine the position of the incision.

Every step of the doctor is cautious and cautious.

In this kind of operation, you will find that the neurosurgeon performs the operation on the patient with his own heart.

This "burning" operation has a greater impact on the human brain than hydrocephalus and worm-picking operations. Hydrocephalus is just to attract "water", and picking bugs is picking up foreign objects. If it is "burned", as long as the "burn" is wrong, the human brain may be indispensable in every cell, and the consequences will be much more serious than the heart.

This is why doctors for mild patients like the young man don't advocate surgical treatment. The effect of surgery is uncontrollable, and in mild cases, surgery is statistically worse than no surgery. The 18-bed critically ill patient had no choice, and the patient and his family members were known to be a dead horse as a living horse doctor before the operation. In order to achieve better results, according to past experience, doctors need to enlarge the "burn" like resection, which is like a big gamble.

What does such an operation mean?

Xie Wanying and a group of students once again realized the limited understanding of the human brain in medicine.
