The electric knife couldn't go in, and the doctor couldn't see, so the method of electrocoagulation to stop bleeding was rejected first.
In surgical operations, what to do if there is severe bleeding? Block the arteries and veins that are the source of the bleeding. Under the current circumstances, doctors are not prepared to perform thoracotomy on children as a last resort, so it is impossible to adopt this approach.
If you want to block the artery without opening the chest, there is another method, which is embolization of the artery commonly used in interventional surgery. This is an interventional surgery in the respiratory tract.
The Department of Respiratory Medicine in the National Association does not carry out such interventional surgery. This is also why the Department of Respiratory Medicine in the National Association is called a weak department. Technically, it cannot reach the level of gastroenterology and cardiovascular medicine. Many diseases of the same disease
Treatment simply cannot be compared with the traditional and famous cardio-thoracic surgery.
The most painful thing for the Department of Respiratory Medicine is that since they have not performed such an operation, the Department of Cardiovascular Medicine in their own hospital is planning to grab business. Last time, the Department of Cardiovascular Medicine was preparing to perform pulmonary artery thrombolysis. It was even mentioned as a prominent figure in the field of cardiovascular interventional surgery.
The famous Guozhi's pulmonary interventional surgery technology is far behind that of the National Internal Medicine Department.
Talking about the current case, it is impossible to perform interventional surgery. There is no interventional surgical equipment such as imaging machines in the dental operating room, and they do not perform interventional surgeries.
New technology cannot be used, so old technology can only 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 to stop bleeding, the first step is not about incision or the use of hemostatic drugs, but about compression and hemostasis. The human body has its own coagulation mechanism to stop bleeding. Compression and hemostasis is when doctors use the body's own coagulation mechanism to stop bleeding.
The blood vessel break becomes smaller and the blood flow slows down, giving time for platelets, fibrin and other coagulation substances to coagulate at the break to form thrombus and stop bleeding, reducing blood clots from traveling around to unnecessary places.
The first patient that Xie Wanying came to China to rescue was compression hemostasis. Compression hemostasis is not limited to on-site emergency first aid. In many cases, doctors also use compression hemostasis during surgery.
For example, the balloon mentioned before 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 expand the inner diameter of blood vessels to clear the blocked narrow mouth.
What is another function of the balloon? Xie Wanying saw it when she went to the second internship of general surgery, a three-lumen two-balloon tube to compress and stop bleeding.
Is it okay to cut a section of the three-lumen two-bag tube and use it here to stop bleeding? No, the tube is too thick. The human digestive tract is much thicker than the trachea, let alone the trachea of a child. It doesn’t matter, the principle is universal. Make one yourself
Similar balloons.
Then I thought of sterile gloves. There is a precedent in the surgical circle for gloves to be made into balloons to stop bleeding. It is in obstetrics. The common method of hemostasis in obstetrics is to use a water bag to stop bleeding. The doctor injects saline into the sterile gloves and ties it up to form a ball of water.
The sac is placed into the uterus of a woman with heavy bleeding to compress the bleeding uterine wall to stop bleeding.
Obstetricians no longer need such crude homemade tools. Medical device manufacturers produce a variety of obstetric hemostatic balloons for doctors to choose from based on clinical needs. Moreover, when this method was first invented, the doctors used it.
Instead of using sterile gloves and a hydration bag, use a catheter and a condom.
