Chapter 232 Basic treatment of snake bites, do not change either

Anastomosis, suturing, and knotting are two surgical techniques that are closely related. Nowadays, anastomosis is only a proficiency level.

And his continuous suturing techniques, square knots, and surgical knots are all at the Xiaocheng level, which is equivalent to being upside down.

The level of basic skills is one level higher than that of advanced skills, which naturally allows the level of advanced skills to be improved quickly.

After practicing several times and mastering the basic steps of advanced skills, your progress will be as fast as flying.

Successfully anastomosing a blood vessel increases proficiency by 10 points, which may seem exaggerated, but is actually quite normal.

When his anastomosis, suturing, and knotting are at the same level, his improvement will become slow. It will even be affected by his suturing and knotting. Only when they improve can the anastomosis be advanced.

Li Jingsheng had more confidence this time and chose the anterior tibial artery for anastomosis.

"Director Hua, arteries and blood vessels have higher requirements for anastomosis technology, so it is still a bit worrying to ask him to do it!"

Director Bi was still a little worried.

"The great saphenous vein is not broken. Aren't there only a few blood vessels that need anastomosis? Let him try. If it doesn't work, let Director Chen take over."

Director Hua acts as a strong backing for Li Jingsheng.

With his words to tell the truth, Director Bi had nothing to say.

At this moment, Li Jingsheng has become more and more courageous, and his anastomosis technology has continued to make breakthroughs and become more proficient. Some of the imperfections in the operation have been quickly corrected, as if he is a surgeon with many years of experience in vascular anastomosis.

Compared with the first performance, it is completely different.

Director Hua's smile became thicker and thicker, and his eyes narrowed with laughter.

Chen Anchen looked at Li Jingsheng's operation with a look like a monster. This guy is indeed a genius. The difficulty of anastomosis of blood vessels is quite high, but it is not something you can do well if you master the suturing technique.

Because when anastomosing blood vessels, each stitch needs to leave at least three to four centimeters of suture, and keeping them from knotting is enough to give many doctors a headache.

Next, you need to ensure that every stitch is accurate.

Because you cannot sew or lock a stitch, you must reserve enough space first to ensure that the subsequent anastomosis can go smoothly.

Therefore, when inserting the needle, insert the needle from the broken end A of the blood vessel, and then insert the needle from the broken end B and exit. It is difficult to master this needle position well without practicing thousands or tens of thousands of times.

Li Jingsheng made many novice mistakes when he performed his first vascular anastomosis.

But looking at his current operations, every move is so sophisticated, making people really envious of his talent.

Ou Qinglan was also worried about her boyfriend at first, but now her bright eyes were full of smiles, admiration and pride.

This time, Li Jingsheng only took less than five minutes to anastomose this important artery and blood vessel.

Only the last one is left.

He rushed to do it without hesitation, and when Director Hua saw this performance, he naturally smiled knowingly.

What general doesn't want his soldiers to fight bravely?

Li Jingsheng rushed to anastomose the last blood vessel. This progressive and hard-working spirit naturally made Director Hua happy.

In order to obtain exercise opportunities in the operating room, one has to rely on grabbing them.

This time it took four minutes and fifty seconds, and the time was shortened by another ten seconds. And the agreement is getting better and better.

The sutures are tight and fine, and the blood vessels fit tightly.

What's even more rare is that the size of the vascular anastomosis is also very good, and there is no obvious anastomotic stenosis.

Regardless of intestinal anastomosis or vascular anastomosis, it is easy to cause the internal space of the anastomosis site to narrow.

This affects blood flow.

There are many consequences, such as insufficient blood supply to the extremities of the limbs, weakness in walking, edema, inexplicable pain, etc. It may also cause an increase in intravascular pressure, and over time, the blood vessels will harden.

"Loosen the tie and do a blood test!"

Director Hua said directly to Li Jingsheng.

When binding limbs to stop bleeding, do not do it for too long.

Usually it needs to be loosened once every half hour or so to allow the end of the limb to receive blood supply.

Except for severe injuries.

The most common thing is that after someone is bitten by a snake or spider, they are worried that the venom will invade the heart, so they are tied up tightly.

However, he lacked the necessary medical knowledge. By the time he was sent to the hospital, the ends of the tied limbs were already bent, purple and cold. When the doctor asked, he learned that the binding time was much longer than half an hour.

The result can be imagined. It might not be a big deal at first, but with such a bundle, the extremities of the limbs lost blood for too long, leading to irreversible necrosis.

Then amputation is required.

This is such an injustice.

Patients who make the above mistakes are relatively rare, because now the national literacy level has improved, and junior high school students will learn some first aid knowledge.

There is another mistake that most patients are most likely to make.

After being bitten by a highly venomous snake, tie the upper end of the wound near the heart to prevent the snake venom from invading the heart.

In fact, doing so will most likely lead to amputation.

Of course, it depends on where you are. If you are in a mountainous area where transportation is inconvenient and the time to get to the hospital is too long, tying up is a very good way to save your life.

It is better to lose a leg than to have venom invade the whole body and cause death.

But if you are in the city, the best way is to go to the hospital for emergency injection of the corresponding type of antivenom.

Because after binding, the venom of highly venomous snakes is very deep and highly toxic.

It is concentrated in a small area at the end of the limb and can cause necrosis of the end of the limb.

When sent to the hospital at this time, it is often difficult to save the leg.

Also, many people watch TV and movies. After being bitten by a poisonous snake, they make a cut to squeeze out the poisonous blood, or even suck it out through their mouths.

This is all undesirable behavior.

Some snake venoms can cause bleeding.

If you scratch the wound, the bleeding will be difficult to stop. Moreover, it will be extremely difficult for the wound to heal after being scratched by a snake.

The best way is to avoid being bitten by venomous snakes.

After Li Jingsheng untied the bandage on the patient's leg, blood immediately began to flow.

You can see that the blood vessels are filling up little by little.

The first anastomotic vein leaked.

The second anastomosis was normal, but the vascular anastomosis seemed narrower and the venous blood return was extremely slow.

"Director Hua, can I reanastomose this vein?"

"Hurry up and do it! There's no need to ask."

Director Hua may have felt that he was losing face, so he signaled to Li Jingsheng to be smarter.

There are doctors from other departments present.

Li Jingsheng asked the nurse to bring a needle holder and sutures to ligate the vein first. At this time, the sliding knot came in handy.

He didn't dare to embarrass the department again.

He quietly spent 43 health points to upgrade Sliding Knot from proficient to mastery.

He has a specialist-level knotting ability, which is barely enough for a place full of masters.

Seeing Li Jingsheng skillfully ligating blood vessels and making a strong and beautiful slip knot, the whole process was very skillful. This made Director Hua nod again.

Director Bi glanced at it and didn't care about it anymore.

In any case, Director Bi was satisfied that the two arteries anastomosed by Li Jingsheng were unobstructed.

His performance is not particularly outstanding, but he is already a unicorn among doctors of his age.

This young doctor in the orthopedic surgery department is really good.

After Li Jingsheng removed the sutures, he trimmed both ends of the blood vessels again and then re-anastomized them.

The length of blood vessels is fixed and has a certain degree of elasticity, but it can only be trimmed once or so at most.

If the blood vessel loses too much length, it will not be able to anastomose properly.

At this time, either an artificial blood vessel is connected or the great saphenous vein is harvested for blood vessel transplantation.

Superior doctors are generally reluctant to allow young doctors to anastomose important blood vessels because of these concerns.

Because the risk is indeed very high.

Soon, the reworked vein was successfully anastomotic.

Li Jingsheng breathed a sigh of relief.

After the smooth knot of the ligation is untied and the blood circulates, everything is normal.

He breathed a sigh of relief.
