Chapter 482

Chen Cang's sharp, fast and stable reset suddenly brightened everyone's eyes!

We have all done replantation of severed fingers and reduction of hand fractures. We are well aware of the particularity of hand joints and bones.

However, it is precisely because he knows that he is even more surprised at how Chen Cang did it!

People will never think it's a coincidence!

At their age, it is better to believe in the reality of strength than to believe in coincidence.

Chen canggang's seemingly random docking is actually subtle.

Huo Guoqing was surprised at first, and then observed carefully.

Naturally, he doesn't think Chen Cang is fooling around. After all, he doesn't say that he is the son of a senior official. Even ordinary patients, Chen Cang won't fool around!

This must be the key to having an internal.

Thinking of this, Huo Guoqing realized that Chen Cang's two hands were constantly fine-tuning. It seemed unintentional, but there was a mystery. In fact, this was also the key.

Chen Cang's eyes stared at the bone end, constantly adjusted through feeling, and then exerted a little force on his hands and fingers, constantly performing subtle operations.

Then, after Chen Cang felt better, he quickly asked Tan Zhonglin to prepare bone nails!

Huo Guoqing always felt that Chen Cang's technique was somewhat familiar. He changed the direction of the bone through the fluctuation of his fingers, and exerted force on both sides

Huo Guoqing frowned!

He promised that he must have seen this technique, but he couldn't remember where it was.

Soon, Tan Zhonglin screws were penetrated, and the stainless steel needle was cross fixed!

At this time, Chen Cang looked at the clock on the wall: another 40 minutes have passed!

At this time, 3 hours and 40 minutes have passed since the hand was broken.

This means that muscle tissue cells have begun to be damaged due to ischemia and hypoxia. If blood vessels cannot be anastomosed in time, it is bound to cause some irreversible damage.

Of course, some cases reported that they were still successful after more than 20 hours, and the amputation effect was very good.

However, this is different from hype and advertising.

Examples cannot represent big data.

Medically, you really can't take those examples.

To put it bluntly, it is: don't take chances!

In front of life, really no one can open and hang at will.

Chen Cang breathed a sigh of relief. Fortunately, these did not waste too much time and would not affect the next vascular anastomosis.

Every step Chen Cang does is to save time and ensure the effect of surgery!

When Chen Cang picked up the "octave mirror", a voice suddenly came from the crowd.

"Dr. Chen... You don't seem to have bone shortening!"

The news immediately made the directors around him secretly say that it was bad.

That's not good news!

Huo Guoqing suddenly realized that Chen Cang really didn't shorten the bone!

What is bone shortening?

Because at the beginning of debridement and cleaning up the soft tissue at the broken end, the necrotic soft tissue will be cleaned, such as pruning, excision and so on

These include neurovascular tissues.

In this way, after debridement, it is bound to affect the length of soft tissues such as blood vessels, nerves and tendons. Because the bones are long, after docking, these tissues of nerves and vessels will be difficult to suture and repair because of insufficient length.

Therefore, in this way, it is necessary to remove the bone end before docking, so that the length of blood vessels, nerves and tendons can be just suitable for suture to achieve better anastomotic effect!

However, Chen Cang clearly did not carry out bone shortening!?

All of a sudden, everyone couldn't help worrying about Chen Cang.

But... It seems inappropriate to point it out in public on this occasion... After all, the patient is still awake!

Even the director who spoke felt a little sorry, but... This is a basic professional quality of a doctor. When necessary, he pointed out the problem and didn't think he had done anything wrong.

Chen Cang didn't speak. "Second disciple" Tan Zhonglin smiled and said, "Dr. Chen likes to count the wear of the bone end during debridement, and has done a good job in shortening the bone in advance from the beginning."

After that, Tan Zhonglin pointed to the wound surface and said, "you see, the length of vascular anastomosis is just right!"

The crowd immediately approached and looked carefully. At this look, they were stunned!

Because it's really just right!

This time, the people couldn't help looking at each other, and their eyes were full of incredible.

During debridement of soft tissue, the bone surface is cleaned at the same time, so as to complete bone shortening?

This... Seems to be a good idea. Can you try it in the future!

The blood vessels of the arm are much thicker than those of the wrist and fingers. They can be sutured even without an operating microscope.

However, no matter how good the vision is, it is impossible to judge the damage degree of tissue, especially vascular intima, with the operating microscope, so as to achieve the purpose of fine vascular anastomosis.

At this time, Tan Zhonglin and an Yanjun immediately put down their work and carefully watched Chen Cang's blood vessel suture.

To tell the truth, up to now, neither of them has studied Chen Cang's vascular suture thoroughly. It seems ordinary, but there is always a mystery.

Tan Zhonglin and an Yanjun have to see Chen Cang once a week. Especially recently, they found that Chen Cang has a deeper and deeper understanding of vascular suture, which seems to have an unspeakable reason.

Huo Guoqing looked at Chen Cang's suture. Well, the most commonly used discontinuous through suture method. This suture method has less damage to the blood vessel wall and is not easy to cause stenosis, but it takes more time, because the operation requirements are high!

However, Chen Cang's next sewing suddenly refreshed Huo Guoqing's understanding of this traditional sewing method!

Is this... Really a discontinuous through seam method?

Are you sure it's not a continuous through seam?

Dr. Chen! Are you... So fast?

The director of the original office was also stunned and had some shortness of breath. Dr. Chen... How fast!

Won't it cause side effects so soon?

Will it affect blood circulation?

Everyone began to whisper and communicate curiously.

……

Without distractions, Chen Cang first sutured a vein and an artery, then began to suture veins, and finally sutured arteries.

This detail made the directors nod slightly. It's a good idea to have an artery first, which can really help those ischemic tissues.

Before long, Chen Cang finished stitching!

At this time, in order to see the stitching effect, they looked closely.

After the anastomosis, the arteries and veins were well filled, the skin gradually began to recover color, and the filling time of capillaries... Did not exceed two seconds!

All the signs show that Chen Cang's vascular suture is very successful!

People looked up and looked at the young man with some emotion. It was really powerful!

From the beginning to now, the time is less than 2 hours. Basically, the hand has been saved. The blood vessel anastomosis is good. It can be said that the operation has been successful.

So far, it is basically guaranteed that this hand has been saved!

Moreover, the time consumed from beginning to end also exceeded their understanding of broken hand suture.

Doctors ask themselves, are they so fast?

Everyone shook their heads with emotion!

Since ancient times... A teenager!

……

PS: today, a reader asked, can we use epidural anesthesia for hand surgery? I can give you a little science here, so that you can only have a general understanding of anesthesia.

In theory, epidural block can be used for any operation except the head.

However, from the perspective of safety, epidural block is mainly used for abdominal and lower limb surgery, including Urology, obstetrics and Gynecology and lower limb surgery.

For hand surgery, if there are no general symptoms, there is no need for general anesthesia, because general anesthesia will have some effects on respiratory tract, and the use of high epidural anesthesia can better grasp the anesthesia time. It seems that this friend still knows something about anesthesia.
