Bed 18 is having surgery today.
In neurosurgery, the most important thing to learn is positioning and repositioning. Only accurate positioning can minimize intraoperative damage and avoid postoperative sequelae.
As mentioned in the previous surgery, before the surgery, bed 18 will be sent to the MRI room for positioning and then back, using the 3D navigation system. For this type of surgery, the navigation system alone is not enough. In order to avoid the image drift mentioned last time, the doctor will use a special method to position during the surgery.
It is not the ultrasound we talked about last time, but the electrophysiological positioning. Speaking of electrophysiological positioning, we can quickly think of the positioning problem encountered by Wei during the interventional ablation surgery last time, which also used electrophysiological positioning. Therefore, the principle of this neurosurgery radiofrequency destruction is similar to that of cardiac interventional ablation. The same is to place the electrode to burn the target point after positioning.
Unlike previous examinations, electrophysiological localization is not affected by other factors over time. It is an immediate examination and is more accurate.
Does this mean that other preoperative examinations are not necessary? No.
Medicine is like this. It is best if all tests can verify each other to pursue the highest diagnostic accuracy. This is to follow the evidence-based rule of each scientific discipline. It is just that the results of an isolated test are afraid of errors. The instrument is not 100% error-free and can also be affected by some unknown factors.
Therefore, doctors need to follow the procedures as much as possible, follow the diagnosis and treatment standards, and insist on completing every necessary examination for the patient, even if some family members and patients do not understand and complain about too many examinations.
In neurosurgery, a department with such an important positioning, examinations must be done more accurately to ensure that the doctor's judgment during the operation is correct.

Before the operation began, the medical staff was very busy. The busiest ones were the young doctors, who went back and forth to complete all the errands. They would then send the patient to the MRI and CT room, and then directly send the patient to the operating room.
Senior doctors will give young doctors appropriate opportunities to practice in the operating room and put head frames on patients.
This time, the head frame was a bit heavy, like a globe, with the ball in the middle becoming the patient's head. As introduced last time, there were several rulers on the head frame for measuring, and they kept measuring.
We measured again and again, checked the navigation system, looked again and again, and discussed again and again. An hour passed. Finally, we arrived at the final location for the incision.
The doctor is cautious with every step.
During this type of surgery, you will find that the neurosurgeon is operating on the patient with his or her own heart at stake.
This "burning" operation has a greater impact on the human brain than hydrocephalus and picking out worms. Hydrocephalus is just to remove the "water", picking out worms is to remove foreign objects. If the "burning" is done wrong, the human brain, especially in every cell, may be indispensable, and the consequences will be much more serious than the heart.
This is why doctors do not recommend surgery for mild cases like the young man. The effect of surgery is uncontrollable, and in statistics, surgery is worse than no surgery for mild cases. The seriously ill patient in bed 18 has no choice. The patient and his family knew before the operation that it was a last-ditch effort. To achieve better results, according to past experience, doctors have to expand the "burn" like resection, which is like a gamble.
What does such an operation mean?
Xie Wanying and a group of classmates once again realized the limited knowledge of medicine on the human brain.
