In neurosurgery, the most studied thing is positioning and repositioning. Only accurate positioning can minimize intraoperative damage and avoid postoperative sequelae.
As mentioned in the previous surgery, before the surgery, the 18 beds need to be sent to the magnetic resonance room for positioning and then back, using a three-dimensional navigation system. For this type of surgery, only using the navigation system is not enough. In order to avoid what was said last time
If the image drifts, the doctor will use a special method to position it during the operation.
It is not the ultrasound mentioned last time, but the electrophysiological positioning used. Speaking of electrophysiological positioning, we can quickly think of the positioning problem encountered by Mr. Wei last time when he performed interventional ablation surgery, which also used electrophysiological positioning.
Positioning. Therefore, the principles of radiofrequency destruction of neurosurgery and cardiac interventional ablation are similar. After positioning, electrodes are placed to burn the target.
Unlike previous examinations, which are interfered by other factors over time, electrophysiological positioning is a real-time examination and is more accurate.
In this way, does it mean that other preoperative examinations can be omitted? No.
Medicine is like this. It is best for various examinations to support each other to pursue the highest diagnostic accuracy. This is to follow the evidence-based rules of every scientific discipline. It is just that the results of an isolated examination are afraid of errors. The instrument is not 100% error-free.
Yes, 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 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 position, examinations must be done accurately to ensure that the doctor's judgment during the operation is correct.
For this reason, before the operation started, the medical staff were very busy. The busiest one was the young doctor, who went back and forth to take care of all the errands. He then sent the patient to the MRI CT room, and then directly sent the patient to the operating room.
Senior doctors will give young doctors the opportunity to practice their skills properly in the operating room and put patients on the headrest.
This time, the metal head frame was installed. It was a bit heavy and looked like a globe. The ball in the middle became the patient's head. As introduced last time, there were several rulers on the head frame to measure.
stop.
I measured again and again, checked the navigation system against the benchmark, looked again and again, discussed and discussed again. An hour passed. Finally, we arrived at the final location of the incision.
The doctor is cautious and cautious every step he takes.
In this kind of surgery, you will find that the neurosurgeon performs the surgery on the patient with his own heart in mind.
This "burning" operation has a greater impact on the human brain than hydrocephalus and worm-picking operations. Hydrocephalus only diverts "water", and worm-picking is to pick out foreign objects. For "burning", as long as "burning"
"Wrong, the human brain, especially in every cell, may be indispensable, and the consequences will be much more serious than the heart.
This is the reason why doctors do not advocate surgical treatment for mild patients like this young man. The effect of surgery is uncontrollable, and surgery for mild cases is statistically worse than no surgery. 18-bed severe patients have no choice. Patients and
The family members knew before the operation that the doctor was a dead horse. In order to achieve better results, according to past experience, the doctor had to enlarge the "burn" like a resection, which was like a big gamble.
What does such an operation mean?
Xie Wanying and a group of other students once again realized that medicine has limited knowledge of the human brain.
