Chapter 483 Since Ancient Times... A Boy!

Chen Cang's sharp, fast and stable reset method immediately made everyone who was doing it shine!

Everyone has done replantation of severed fingers and reduction of hand fractures, and is well aware of the particularity of hand joints and bones.

However, it was precisely because he knew that he was even more surprised, how did Chen Cang do it!

No one would think it was a coincidence!

At their age, instead of believing in coincidences, it is better to believe in the reality of strength.

Chen Cang's seemingly random connection just now was actually all subtle.

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

He naturally didn't think that Chen Cang was fooling around, even an ordinary patient, Chen Cang wouldn't mess around!

That must be the key to having internals.

Thinking of this, Huo Guoqing realized that Chen Cang's two hands were constantly making fine adjustments, which seemed to be unintentional, but hidden a mystery. In fact, this was the most crucial point.

Chen Cang's eyes were fixed on the end of the bone, and he constantly adjusted by feeling, and then the fingers of both hands were slightly forced, and he kept making subtle operations.

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

Huo Guoqing always felt that Chen Cang's technique was a little familiar. This kind of change the direction of the bone through the fluctuation of the fingers, using 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's screws were penetrated, and the stainless steel needles were also cross-fixed!

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

At this point, 3 hours and 40 minutes had passed since he was cut off.

This means that muscle tissue cells have already begun to be damaged due to ischemia and hypoxia. If vascular anastomosis cannot be performed in time, some irreversible damage will inevitably occur.

Of course, there are also some cases that have reported that they were still successful after more than 20 hours, and the effect of amputation was good.

But what's the difference between hype and advertising.

Individual cases are not representative of big data.

Medically, you really can't talk about those cases.

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

In the face of life, no one really can hang up at will.

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

Every step Chen Cang takes is to save time and ensure the effect of the operation!

Just when Chen Cang picked up the "eight-fold mirror", a voice suddenly came from the crowd.

"Doctor Chen...you don't seem to be shortening the bone!"

The news immediately made the directors around them feel bad in their hearts.

This is not good news!

Huo Guoqing suddenly realized that Chen Cang didn't seem to have undergone bone shortening!

What is bone shortening?

Because at the beginning of the debridement, when cleaning the soft tissue at the broken end, the necrotic soft tissue will be cleaned, such as trimming, excision, etc...

These include tissues such as nerves and blood vessels.

In this way, after debridement, the length of soft tissues such as blood vessels, nerves, tendons, etc. will inevitably be affected, and because the bones are long, after docking, the nerve blood vessels and these tissues will be difficult to suture and repair due to insufficient length.

Therefore, in this way, it is necessary to perform a resection before the butt joint of the bone ends, so that the length of the blood vessels, nerves, and tendons can be just suitable for suture, and a better anastomosis effect can be achieved!

However, Chen Cang clearly did not perform bone shortening! ?

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

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

Even the director who spoke felt a little apologetic, but... this is the basic professional quality of a doctor. When needed, he points out problems. He doesn't think he has done anything wrong.

Chen Cang didn't speak, but "Second Disciple" Tan Zhonglin said with a smile: "Doctor Chen likes to take into account the wear and tear of the bone ends during debridement, and has already shortened the bone in advance from the beginning."

After speaking, Tan Zhonglin pointed to the wound and said, "Look, the length of the vascular anastomosis is just right now!"

Everyone immediately got closer and looked closely, and when they saw it, they were stunned!

Because it's just right!

This time, everyone couldn't help but look at each other, their eyes full of incredible.

When debridement of soft tissue, clean the bone surface at the same time, so as to complete the bone shortening?

This... seems to be a good idea, can I try it in the future!

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

However, no matter how good the vision is, it is impossible to judge the damage of the tissue, especially the intima of the blood vessel, with the operating microscope, so as to achieve the purpose of finely anastomosing the blood vessels.

At this time, Tan Zhonglin and An Yanjun on the side immediately put down their work and watched Chen Cang's blood vessels suture carefully.

To be honest, neither of them has thoroughly studied Chen Cang's blood vessel sutures. It seems ordinary, but there are always hidden secrets.

Tan Zhonglin and An Yanjun have to see Chen Cang for an operation every week, especially recently, they found that Chen Cang's understanding of vascular suture is getting deeper and deeper, which seems to have an inexplicable reason.

Huo Guoqing on the side looked at Chen Cang's suture, um, the most commonly used intermittent suture method, this suture method does less damage to the blood vessel wall and is not easy to cause stenosis, but it is more time-consuming because the operation requirements are high!

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

This...is it really interrupted stitching?

Are you sure it's not a continuous penetration suture?

Doctor Chen! Are you... so fast?

The director at the original place was also stunned, and he was short of breath. This Doctor Chen... so fast!

Wouldn't it cause side effects so quickly?

Will it affect blood flow?

Everyone began to whisper and exchange curiosity.

...

Chen Cang had no distractions, first sutured a vein and an artery, then started to suture the vein, and finally sutured the artery.

This detail made these directors nodded slightly. It was a very good idea. First, an artery can indeed help those ischemic tissues.

It didn't take long for Chen Cang to sew up!

At this time, in order to see the stitching effect, everyone got close and looked at it.

I saw that the arteries and veins after the anastomosis were well filled, the skin gradually began to recover its color, and the time for capillary filling... It didn't take more than two seconds!

All the signs show that Chen Cang's blood vessel suture was very successful!

Everyone looked up and looked at this young man with some emotion, it was really amazing!

From the beginning to the present, it took less than 2 hours, and the hand was basically saved, the blood vessels were anastomosed well, and the operation was basically successful.

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

Moreover, the time consumed from start to finish is beyond their knowledge of severed hands and sutures.

One by one the doctors asked themselves, are they so fast?

Everyone shook their heads with emotion!

Since ancient times... a boy!

PS: Today, a reader asked, can epidural anesthesia be used in hand surgery? I can give you a little bit of popular science here, so that you only have a general understanding of anesthesia.

In theory, epidural blocks can be used for any procedure except the head.

However, from a safety point of view, epidural block is mainly used for operations on the abdomen and below, including urinary, obstetrics, and lower extremity operations.

For hand surgery, if there are no systemic symptoms, general anesthesia is not necessary, because general anesthesia will have some impact on the respiratory tract, and the use of high-level epidural anesthesia can better grasp the time of anesthesia. It seems that this friend is still Know something about anesthesia.
