Some of the things recorded may not be profound, but they are objective summaries of clinical work, and many people who have done it all their lives without thinking about it can never discover the mystery of it. Among them, regarding the management of acute edema, I make a point that there is no circulation, no effect. The reason is that we often have to deal with some rapid occurrence, accompanied by a metaplasia or inflammatory reaction to the swollen tissue, sometimes in the head and face, sometimes in the neck, the latter is particularly dangerous, often leading to airway obstruction, the occurrence of asphyxiation death is by no means rare. Recently the department admitted another case, and the doctor on duty asked me what drugs are best to use, what antimicrobials, what hormones, and after thinking about it for a while, I told him that no matter what drugs, if the edema is too great and the local blood circulation is stagnant, they will not be effective because the drugs cannot reach the site we need through the circulation, which is why the inflammatory tissue swelling is often accompanied by necrosis, because The local circulation is destroyed by the excessive swelling, and the local tissue cells are deprived of blood and oxygen, so of course they cannot escape from necrosis. Therefore, we propose a new treatment point of view, for the treatment of extremely swollen tissues, we also need to consider restoring the circulation, how to restore the circulation? First, consider the possibility of decompression. Just as in the treatment of osteofascial compartment syndrome, a long pull is needed first, in extremely swollen tissues, it is possible to release blood to heal the wound when necessary, sacrificing a little blood, a less serious wound, in exchange for the possible preservation of more tissues. Secondly, the use of blood-activating and vasodilating drugs is emphasized. Once again, physical therapy should be strengthened, including the external application of magnesium sulfate, etc., with these clinical thinking, we deal with acute cases, so that we do not have only one means of drugs.
