During surgery, we usually avoid large blood vessels and operate in places with relatively few blood vessels, so the total amount of bleeding is not much. At the same time, we need to record the amount of bleeding, and there will be these assistants who help the surgeon to operate. When there is bleeding, a small number of oozing assistants will use gauze to keep the operation area clear, which will not affect the observation and operation. If there is a large amount of bleeding, a vacuum pump will suck the blood away.
Therefore, the patient's blood type should be checked during the operation, and then blood should be prepared, that is, blood with the same blood type should be prepared. In addition, bleeding should not be stopped during the operation. First, blood vessels should be avoided to control the amount of bleeding, and then the amount of bleeding should be recorded during the operation. This is a blood-sucking tool that can be seen intuitively. Once the blood is sucked, the operation interface should be kept clean, and the vision will not be affected. For the operation with a large amount of bleeding, the blood transfusion should be performed at the same time, and some blood-activating drugs will be used
Let the blood circulation be maintained, and then make up as much as it flows out. Therefore, when some operations are bleeding, a lot of blood needs to be lost while doing it. It doesn't stop the bleeding. After the operation, we need to wait and see if there is any bleeding or leakage at the suture site, and it will be over if there is no bleeding.
It's a problem to recheck when there is leakage with a bleeding amount larger than normal. Some small blood vessels cut in the operation will be ligated without connecting them, so there will be no leakage and bleeding. Because blood vessels are networked, like many roads, collateral circulation will be formed, and blood tied in one road will flow through other branches. Therefore, it's not so complicated that every blood vessel has to be reconnected and some of them will be ligated. There is no bleeding after the operation.
Because blood clots are easy to occur during surgery, in order to reduce blood clots, blood activating components should be added to both the transfusion fluid and the transfusion blood, that is, to make the blood not coagulate to reduce blood clots. Because a small operation, if it produces a small thrombus and gets blocked in the brain, it is a stroke, so it doesn't stop bleeding during surgery, but blood transfusion should be given as much as possible, and blood activating components should be added to prevent blood coagulation. It will be maintained for a period of time after the operation, for fear of thrombosis, so it won't stop bleeding.
The hemostasis in the operation is mainly bleeding during the operation. At this time, various emergency hemostasis methods such as hemostatic forceps, hemostatic cotton, tourniquet, ligation and electroacupuncture can be used to stop bleeding. The bleeding site is directly blocked and ligated, and then the operation is carried out. If the same amount of bleeding is large, there is no need to lose blood. This is how the operation is completed.
