Chapter 3186 [3186] Difficulties

The cool doctor Tong couldn't help laughing out of his throat.

Who makes such a scene so rare.

Doctor Charlie is now talking with a face that is too serious to be serious.

When the students who came to the operating room later saw this scene, the playboy Chang Jiawei who was the first thing they could think of could only become serious when they met Mr. Xie. It can only be said that this foreigner is not as good as Mr. Chang, and his reaction is half a beat slower.

Pan Shihua was filled with emotions. I remembered that he wanted to make a joke about classmate Xie before, but classmate Xie picked him up by 0.01. Therefore, Xie Tong's problem of governing people is definitely super-class.

The foreign uncle speaks, and now he speaks well-behaved academic words:

reference plane and reference line.

(reference plane reference line)

The boss is very experienced, and what he pointed out hits the nail on the head.

As she thought, the uncle's sapphire eyes had the calculator spirit that neurosurgeons are good at, and soon realized that her eyes were measuring on the patient's head.

Measurements during surgery are for positioning. In terms of anatomy, as mentioned before, accurate positioning requires the identification of reference planes and reference lines. For example, for the simplest blood pressure measurement, the accurate operation should be to first determine where the cubital fossa is, and then tie the cuff to the distance from the cubital fossa. Accordingly, the cubital fossa is the reference anatomical position.

We have said that the sphenoid sinus is hidden in the skull, and the doctor's eyes cannot see it from the outside. If you want to locate it accurately, there is no other way than relying on the relationship between it and the anatomical position that the doctor can see or touch.

Each person's specific appearance is different, and the bones are not the same. There are similarities in the face, but there are bound to be subtle deviations in the details. Neurosurgery pays attention to precision. For example, the sphenoid sinus is not as small as the ventricle. Bit general rules, it is really a bit of a problem.

As experts like Dr. Charlie know, and even they are sure, there is no conclusive research on finding the reference surface of the sphenoid sinus in today's medicine. It means to find out what reference surface and reference line are needed in the sphenoid sinus, and there is no general method of unified positioning like blood pressure measurement for guidance.

There is no general rule, and clinicians do their own thing. Various reference surfaces and reference lines come out, and there is no unified standard, which means that there is no unified answer. Different reference values ​​may give different results.

This too requires doctors to make the most sensible choice.

Under normal circumstances, doctors have to rely on their medical experience, but today's surgery is a special experience value that is not reliable here.

Several big cows remained silent, including Dr. Charlie. After saying the few words just now, I wonder if they have been "educated" and dare not boast. People have stated their position, if he wants to boast, he must boast to the technical point so as not to lose his own big face.

After the position was set, Xie Wanying withdrew.

Brother Cao is the main surgeon for this part.

After Cao Yong knew that she was almost done, he went outside to wash his hands first.

Doctor Tong came up to help with the disinfection work.

As Senior Brother Cao's assistant, Xie Wanying went outside to wash her hands before entering the operating room.

Whether the positioning result is right or not depends on the results of the surgery. The truth comes out of practice, and the actual effect cannot be judged just by looking at it before the operation. This is also the reason why the big cows are silent first.

The light panel in the operating room turned on the light, and hung up the imaging films of the patients. Dr. Charlie and Dr. Tong stood in front of the light panel and compared them.

In the multimedia conference room, the guests watching finally saw the operation screen displayed on the curtain.
