The electric knife could not enter and the doctor could not see it, so the method of electrocoagulation to stop bleeding was rejected first.
In surgical operations, what to do when there is heavy bleeding? Block the source of bleeding, arteries and veins. In the current situation, doctors are not prepared to perform thoracotomy on children unless it is absolutely necessary, so this approach is impossible. If you want to block the artery without thoracotomy, there is another way, which is arterial embolization, which is commonly used in interventional surgery. This is an interventional surgery within the respiratory system.
The National Association of Respiratory Medicine does not perform such interventional surgery, which is also the reason why the respiratory department is called a weak department within the National Association of Respiratory Medicine. Technically, it is not as advanced as the gastroenterology and cardiovascular medicine departments, and the treatment of many diseases of the same type cannot be compared with the traditional and famous cardiothoracic surgery departments.
The most painful thing for the respiratory department is that they have not performed such operations, and the cardiovascular department of their own hospital is trying to grab the business. Last time, the cardiovascular department was already preparing to perform pulmonary artery thrombolysis. Not to mention Guo Zhi, who is well-known in the field of cardiovascular interventional surgery, and his pulmonary interventional surgery technology is far ahead of the internal medicine department of the National Association.
Back to the current case, it is impossible to do intervention. There is no interventional surgery equipment such as angiography machine in the dental operating room, and they do not perform interventional surgery.
If new technology is not available, then only old technology can be used. Sometimes, the most primitive technology is the most reliable, because many new technologies are just developed on the basis of old technologies.
In surgery, when teaching medical students how to stop bleeding, the first step is not to perform surgery or use any hemostatic drugs, but to use compression to stop bleeding. The human body has its own coagulation mechanism to stop bleeding. Compression hemostasis is when doctors use the body's own coagulation mechanism to make the blood vessel rupture smaller and the blood flow slower, giving platelets, fibrin and other coagulation substances time to coagulate at the rupture to form a thrombus to stop bleeding, and reduce the number of thrombi that run around to unwanted places.
The first patient that Xie Wanying rescued at the National Association for the Treatment of Infectious Diseases used compression hemostasis. Compression hemostasis is not limited to on-site emergency first aid. In surgery, doctors often use compression hemostasis.
For example, the balloon mentioned in endoscopic surgery and interventional surgery. The balloon is a magic weapon for doctors and has many uses. It can be used to expand the lumen, expand the inner diameter of the digestive tract and the inner diameter of the blood vessels to clear the blocked narrow opening.

What is another function of the balloon? Xie Wanying saw it when she was doing internship at the Second Department of General Surgery: a three-chamber two-balloon catheter for compression hemostasis.
Can I cut a section of the three-chamber two-balloon tube and use it here to stop bleeding? No, the tube is too thick. The human digestive tract is much thicker than the trachea, not to mention that this is the trachea of a child. It doesn't matter, the principle is universal. Make a similar balloon yourself.
So I thought of sterile gloves. Gloves made into balloons to stop bleeding have a precedent in the surgical circle, in obstetrics. The common water bag hemostasis method in obstetrics. The doctor injects saline into the sterile gloves and ties them up to make a spherical water bag, which is then placed in the uterus of a bleeding parturient to compress the bleeding uterine wall to stop bleeding.
Obstetricians no longer need such simple homemade tools. Medical device manufacturers have produced a variety of obstetric hemostatic balloons for doctors to choose from according to clinical needs. Moreover, when this method was first invented, doctors did not use sterile gloves and water bags, but catheters and **.
