18 beds were operated on today.
Here in neurosurgery, the most learned thing is positioning and repositioning. Only accurate positioning can minimize intraoperative damage and avoid postoperative sequelae.
As mentioned in the previous operation, before the operation, the 18th bed must be sent to the magnetic resonance room for positioning and then returned, using a three-dimensional 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 the patient during the surgery.
It's not ultrasound as mentioned last time, but electrophysiological positioning. 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. Therefore, the principles of radiofrequency destruction of neurosurgery and cardiac interventional ablation are similar. After positioning, the electrode is 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 if various examinations can corroborate each other to pursue the highest diagnostic accuracy. This is to follow the evidence-based rules of every scientific discipline. It's just that the result of an isolated inspection may be wrong. The instrument is not 100% error-free, and the instrument may 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 some family members and patients don’t understand and complain about too many examinations.
In neurosurgery, which is such an important department, examinations must be done accurately to ensure that the doctor's judgment during the operation is correct.
Before the operation started, the medical staff were very busy. The busiest one is the young doctor, who has to go back and forth to take care of all the errands. Then send the patient to the MRI CT room, and then send the patient directly to the operating room after returning.
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, it was a metal head frame that was a bit heavy, like a globe, and the ball in the middle became the patient's head. As introduced last time, there are several rulers on the head frame to measure and measure continuously.
Measured again and again, checked the navigation system against the benchmark, looked again and again, discussed and discussed again. An hour passed. Finally it was time to finalize the location of the incision.
The doctor takes every step with caution.
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" surgery has a greater impact on the human brain than hydrocephalus and bug-picking surgeries. Hydrocephalus only attracts "water", and picking out bugs is picking out foreign objects. In the case of "burning", as long as the "burning" is 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 patients with mild symptoms like this young man. The effect of surgery is uncontrollable. For mild cases, surgery is statistically worse than no surgery. 18 critically ill patients have no choice. Before the operation, the patients and their families knew that the doctor was a dead horse and a living horse. To achieve better results, according to past experience, doctors have to enlarge the "burn" like resection, which is 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.
