Chapter 4456 [545] Is There Any

Medicine is the same as science, and some truths are discovered directly in practice. Some require scientists (medical scientists) to come up with an idea and then verify the authenticity of the idea.

So you will find that in clinical medicine, many technical surgeries are ideas that clinicians have figured out in practice and then put them into action: Hey, that’s okay~

The human body is a lot of things that are too complicated to explain. Even if the organs and tissues of the human body are repeatedly dissected by scientists in order to thoroughly analyze them, the results can only reveal a corner of the mystery.

For this reason, Dr. Li and Dr. Cui said: I don't know if it will work. Someone has made it and put it in a research paper. The principle, to be honest, you and I both know the mysteries of the human body mentioned above and no one can understand the ultimate goal.

It stands to reason that the "branches" of the lungs are connected, just like a person's blood vessels are connected to a lot of side branches. It should be impossible to control only which bronchi are blocked.

Medicine is the greatest test of courage, as I have said many times before. Clinicians will never give up easily in order to save patients.

Is it true that the "branches" of the lungs are completely connected, so that the air running in all the lungs will pass to a single pleural fistula? Clinicians believe that since senior medical scientists have proposed segmentation of the lungs, it means that not all the "branches" of the lungs are really connected, and not all the "branches" of the lungs can go to the air leakage point.

How to prove this construct of the clinician? Try blocking it and you will know. You can know whether the above idea is true by blocking that bronchial tube and seeing if it has the effect of preventing air leakage.

Which bronchus should I try to block?

Following the previous theoretical basis of the above concept, standing on the shoulders of giants, if there are preoperative imaging data for auxiliary diagnosis, clues can be found in the imaging data to find the lung segment corresponding to the pleural fistula, and the lung segment corresponding to the blockage of bronchi.

If there is no clue, we can only classify the lungs according to their anatomy again, first explore the upper lobes, lower lobes, and middle lobes. If that fails, we can divide the lung segments to explore.

The blockage must be to block the superior bronchus (i.e. "big branch") without exploring the "small branch" of the sub-segmental bronchus. Because there are too many side branches in the sub-section that connect everywhere and may cause air leakage, it becomes meaningless to block one of the sub-sections.

The above words are used as adjectives. If there is a flood, it will be effective to block the big river upstream instead of blocking the small rivers downstream.

What instrument should be used to block it?

The appliances mentioned above should be removable, and it is best to be easily accessible rather than special appliances that have no threshold and are more widely used.

After listening to the description, the experts at the scene quickly thought of a tool commonly used in many medical and surgical operations that almost all doctors are familiar with: the balloon catheter.

To put it bluntly, all nurses, anesthetists and doctors are familiar with this tool.

Urinary catheters, endotracheal intubations, etc. are not all blocked with similar balloon catheters filled with water or air for fixation.

Balloon catheters can only be used in the above-mentioned ways. It should be said that doctors are too good at turning a tool into a kaleidoscope of flowers. This is all based on mathematical physics.

Up to now, balloon-tube medical devices have played a role in many clinical medical departments, and various shapes have been developed to suit their respective clinical specialties. These are all ideas that clinicians have figured out based on their surgical needs.

For example, in the interventional surgery case we just finished, it was mentioned that the balloon catheter is used to dilate blood vessels, and its shape and structure must be much more complicated than that of a urinary catheter.

Dr. Cui, who was familiar with all this, asked the key point: Dr. Li, do you mean that this tool is only seen in papers and is not ready-made?

Dr. Li: It probably doesn’t exist yet. I don’t know if Xie Juan Wang has it himself, or if Xie Juan Wang has thought of where to find a substitute.
