Bed 18 today's surgery.

In neurosurgery, the most important thing to learn is positioning and repositioning. Only when the positioning is accurate can it minimize intraoperative injuries and avoid postoperative sequelae.

As mentioned in the previous operation, before the operation, bed 18 should be sent to the magnetic resonance room to position and then return, and a three-dimensional navigation system is adopted. For this type of surgery, it is not enough to use the navigation system alone. In order to avoid the image drift mentioned last time, the doctor will take another special method to position during the operation.

It is not the ultrasound mentioned last time, but the electrophysiological positioning used. Speaking of electrophysiological positioning, we can quickly recall the positioning problems encountered by Mr. Wei during the interventional ablation surgery last time, and the same electrophysiological positioning was used. Therefore, the principle of this neurosurgery radiofrequency destruction and cardiac interventional ablation is similar. The same is to place the electrode electroburn target after positioning.

The electrophysiological positioning is not like the previous examination that is disturbed by other factors over time. It is an immediate inspection and has higher accuracy.

In this way, can you stop performing other preoperative examinations? No.

This is the case in medicine. It is best to conduct tests on each other to pursue the highest diagnostic accuracy. This is to follow the rules of evidence-based in every discipline of science. It is just an isolated test result is afraid of errors. The instrument will not make mistakes 100% without errors, and the instrument will also be affected by some unknown factors.

Therefore, doctors need to follow the steps as much as possible, follow the diagnosis and treatment standards, and make every necessary examination complete for the patient. Even if some families and patients do not understand and complain about the many examinations.

In neurosurgery, when positioning such an important department, the examination must be done and precisely done to ensure that the doctor’s judgment during the operation is not wrong.

For this reason, the medical staff were very busy. The busiest one was the young doctor who took back and forth all the errands to complete. He then sent the patient to the magnetic resonance CT room, and then sent the patient directly to the operating room when he came back.

Senior doctors will give young doctors the opportunity to practice properly in the operating room and give patients a headache.

This time, the metal head rack was a bit heavy, like a globe, and the ball in the middle became the patient's head. As introduced last time, several scales on the head rack were measured, and they were measured non-stop.

After measuring, measure and verify the navigation system, check it again and discuss it again. An hour has passed. Finally, it has reached the final position to determine the incision.

Doctors should be cautious every step.

During this kind of operation, you will find that the neurosurgeon holds his heart to the patient for surgery.

This "burn" operation has a greater impact on the human brain than the hydrocephalus and picking insects. Hydrocephalus only attracts "water", and picking insects is to pick foreign objects. If you "burn", as long as you "burn" a little bit, the special nature of the human brain may be indispensable in every cell, and the consequences will be much more serious than the heart.

This is why the young man's doctors do not advocate surgery for mild patients. The surgical effect is uncontrollable. Surgery is statistically worse than inactivity surgery. Patients with severe patients with 18 beds have no choice. Patients and their families are known to be dead before the operation. If you want to achieve better results, the doctors should expand the "burn" like an excision, which is like a big bet.
