18 beds for surgery today.

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

It's not the ultrasound I mentioned last time, but the electrophysiological positioning. When it comes to electrophysiological positioning, we can quickly think of the positioning problem that Wei encountered during the interventional ablation operation last time, and the same electrophysiological positioning was used. Therefore, the principles of this neurosurgery radiofrequency destruction and cardiac interventional ablation are similar. The same is after positioning, put the electrode to burn the target.

Electrophysiological positioning is not like the previous examination, which is interfered by other factors in the passage of time. It is a real-time examination, and the accuracy will be higher.

Having said that, is it possible to skip other preoperative examinations? no.

It is like this in medicine. It is best that various examinations can respond to each other to pursue the highest diagnostic accuracy. This is to follow the evidence-based rules of each discipline of science. Just an isolated test result for fear of making mistakes. The instrument is not 100% infallible, and the instrument is also affected by some unknown factors.

Therefore, the doctor needs to follow the steps as much as possible, follow the diagnosis and treatment specifications, and insist on completing each necessary examination for the patient. Even if some family members and patients do not understand and complain that there are many inspections.

In neurosurgery, in order to locate such an important department, the examination is even more necessary and accurate to ensure that the doctor's judgment during the operation is correct.

The medical staff were very busy before the operation started. The busiest is the young doctor, going 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.

In the operating room, senior doctors will give young doctors a proper opportunity to practice their hands and put the patient on the head.

This time, the metal head frame is a bit heavy, like a globe, and the ball in the middle becomes the patient's head. As I introduced last time, there are several rulers on the headstand to measure and measure.

Measure and measure again, verify the navigation system against the standard, read and review, and discuss again after negotiation. An hour has passed. Finally arrived at the final location of the incision.

Doctors are cautious in every step.

In this type of surgery you will find that the neurosurgeon is operating on the patient with his own heart.

This "burning" operation has a greater impact on the human brain than the operation of hydrocephalus and picking bugs. Hydrocephalus is just to attract "water", to pick a bug is to pick a foreign body. In the case of "burning", as long as the "burning" is wrong, the human brain may be indispensable in every cell, and the consequences will be much more serious than the heart.

This is the reason why doctors like this guy don’t advocate surgery for mild patients. The effect of surgery is uncontrollable, and in mild cases, surgery is statistically worse than no surgery. The 18-bed critically ill patients had no choice, and the patients and their families were known to be dead horses as doctors before surgery. In order to achieve better results, according to past experience, doctors should enlarge the "burn" like excision, like a big gamble.

What does such an operation indicate?

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