Chapter 197 When the operation is in progress

But now it seems that there is no need to worry about this problem at all. Wound bleeding is not a lot of bleeding, and the difference between the two is quite big.

It's just that Director Zhang's nerves have been tense, and he hasn't reacted for a while.

Now after listening to Qin Feng's explanation, he naturally reacted.

Others did not underestimate Director Zhang, but instead showed respect to Director Zhang. After all, Director Zhang really cares about patients and surgery. He does not regard surgery as a task, but more as a responsibility.

Lin Xue wiped Qin Feng's sweat, and after a pause, Qin Feng continued his movements.

Next, is the suture of the vein.

Although the shadowless lamp has no shadow and will not cause obstacles to the field of vision, but because it is too bright, people's eyes will get tired if they are exposed to this kind of light for a long time.

Although doctors like Qin Feng often work in the shadowless lamp environment and are familiar with the light of the shadowless lamp, the current operation lasted for five hours, and the microsurgery also places great demands on people's eyes. Therefore, if you concentrate for a long time, you will get tired.

Microsurgery is not like an ordinary surgical operation. For other surgical operations, if you panic once in a while, it is not a big problem.

But in microsurgery, panic at any moment may delay time and require re-preparation for this step of surgery.

Qin Feng closed his eyes, let his eyes rest for a while, opened them again, and sewed them up again.

As for the bleeding at the suture end of the finger, Qin Feng did not take care of it. It proves that the artery at the suture end of the finger has allowed blood to pass through, and then the veins are anastomosed, so that the blood vessels passing through return to the heart, and the blood circulation at the finger is smooth. established.

It's just that the diameter of the vein is relatively thick, and it is less difficult for Qin Feng to suture the vein than the artery.

Director Zhang watched seriously from the sidelines, although Director Zhang is old now, in fact Director Zhang is still eager to learn.

Qin Feng's hand anastomosis surpassed many hand surgeons.

Arterial and venous anastomosis, there are many ways of anastomosis, some are port anastomosis, some are vascular anastomosis, both are anastomosis of two blood vessels.

But the finger is different. The finger is full of reticular blood vessels, which is what we commonly call spider web-like blood vessels. It is densely packed. This kind of blood vessel network is difficult to judge which is an artery and which is a vein. The characteristics of arteries and veins in textbooks , the difference is very clear, but in actual operation, in addition to being familiar with the organizational structure, you must also have your own little skills.

Otherwise, once the blood vessels are divided wrongly, the blood that originally flowed through the veins will enter the arteries, causing the blood circulation system to collapse.

The first point of this kind of operation is to straighten the blood vessels, which is a very cumbersome job, which is why Qin Feng has to mark the blood vessels one by one.

Qin Feng is also a person who is cheating. After so many surgical trainings in the training room, Qin Feng can distinguish the vascular network at the fingertips and toes without a single glance, at most two or three.

Practice makes perfect, this sentence is not just words.

While Qin Feng was straightening out his veins, Director Zhang looked a little dizzy.

"Xiao Qin, slow down, I haven't seen what the blood vessels look like, so you're going to divide them."

"What's the use of looking at that thing?" Qin Feng asked back.

Director Zhang was so choked up that he couldn't speak, so he could only continue to watch Qin Feng divide his blood vessels in silence.

Although Qin Feng couldn't clearly see the process of dividing the blood vessels, Director Zhang could observe the divided blood vessels.

"You guys sorted it out so fast, you can't make a mistake." Director Zhang muttered to himself.

As his eyes swept over, he roughly checked the three blood vessels. Director Zhang found that Qin Feng's classification was correct. Looking over slowly, he found that none of them were correct.

This……

Fast and accurate?Fast shooter?

Director Zhang continued to watch with some disbelief, and finally he simply stopped watching. Finding fault with Qin Feng's operation was entirely to find himself unhappy.

But Director Zhang also has doubts in his heart. This method of dividing blood vessels, especially the blood vessels that need to be learned in hand surgery, is generally only done by doctors with senior qualifications and rich experience.

But Qin Feng, let alone experience, he didn't come from hand surgery.

but……

Director Zhang suddenly thought that Qin Feng seemed to be from the Department of Vascular. A doctor in the Department of Vascular is familiar with blood vessels, so it's not too much.

Thinking about it this way, Director Zhang felt much better, at least he could comfort himself.

After 10 minutes, Qin Feng let go of his hand.

"Okay, I'm going to start sewing." Qin Feng said.

Director Zhang looked over and hurriedly prepared to suture.

Qin Feng bent down, looked at the microscope, took the suture handed over by Director Zhang, and carefully stitched the blood vessels together.

However, following Qin Feng's movements, Qin Feng quickly discovered several unusual blood vessels, such as some blood vessels that were partially spasmed, and some that were bulging due to poor blood ejection at the proximal end.

Generally, the spasm of blood vessels is caused by the strong contraction of the smooth muscle of the blood vessel wall, resulting in narrowing of the lumen. If Qin Feng sutures directly, the blood flow will be greatly reduced, and it may even cause vascular occlusion, causing adverse reactions such as vascular embolism. Qin Feng still decides Deal with the spasticity first.

There are drugs and physical methods to deal with vasospasm. Qin Feng still chooses the physical method. Although it is slower, it has less impact on the operation.

"Director Zhang, please soak the gauze in warm salt water to cover the spasmed blood vessels."

Director Zhang nodded, covered it with warm gauze, removed it after about 20 seconds, and the spasmed blood vessels returned to normal.

Qin Feng then quickly sutured and completed the connection of the complex network of blood vessels.

Qin Feng has finished the anastomosis of the entire vein.

"Ready to rebuild bones."

Compared with blood vessels, this step is much simpler. Just use Kirschner wires to connect the metacarpal bones of the broken surface with the phalanges of the toes, and then perform splint fixation with orthopedic fixation.

The fixed parts generally only reveal the fingertips, which can not only facilitate the observation of blood circulation, but also allow the bones to grow.

After finishing, Qin Feng turned on the blood circulation, this is to observe the situation of blood vessel anastomosis.

Director Zhang took off the vascular clamp, and the blood flowed out from the heart, quickly passed through the blood vessels into the two toes, circulated once and then returned to the veins.

After waiting for about a dozen cycles, Qin Feng breathed a sigh of relief when the blood vessels did not appear.

This vascular anastomosis, logically speaking, is the first time it has been implemented, and it is also the first time for Qin Feng in reality. It is a bit risky, but the result is quite satisfactory.

However, this only means that the anastomosis of the blood vessels is better. The final effect depends on the healing of the patient's bones and whether the blood vessels will be hindered.
