2. Within 24 hours after injury, before the formation of congestion, you can use an ice pack for cold compress (if there is no ice pack, you can wrap it with a towel or directly compress it) to reduce the bleeding after microvascular rupture and reduce the degree of congestion. This is well-known common sense, so I won't go into details.
3, timely use of fire therapy after injury can quickly eliminate blood stasis and reduce the formation of blood stasis. Buy a bottle of medical disinfectant alcohol, then put a cotton ball with tweezers and dip it in alcohol. It is best not to drip alcohol automatically. Light the cotton ball and roll back and forth on the injured part. After the cotton ball goes out, dip it in alcohol and roll it repeatedly 15 minutes or more. In the later recovery process, do fire therapy two or three times a day, and the speed of removing blood stasis is good.
4. For dense and serious punctate congestion or massive congestion, the method of bloodletting and blood stasis can be adopted. Pierce the cortex with sterilized glass, etc. To squeeze out the blood stasis, or use cupping to suck out the blood stasis after puncture. It should be noted that after puncture and bloodletting, the wound must be disinfected to maintain hygiene and prevent infection. This method is effective and fast in removing blood stasis, but there is no medical common sense and knowledge, so it is not recommended to use this method to remove blood stasis
5, boiled eggs are also highly respected by people, but they are often more suitable for minor abrasions, and the effect on severe abrasions is not good. The specific method is: cook the whole egg, peel it, then roll it back and forth at the bruised place when it is hot, and then heat it with boiling water when it is cold, and roll it repeatedly for at least 15 minutes each time, and do it at least twice a day.
6. In some places, hospitals or sanatoriums have set up blood-sucking therapy and other projects, using bloodsucking animals such as leeches to suck blood and dredge the human body. This method is effective in removing blood stasis and fast, but it takes a little courage.
7. In addition to the bruises caused by trauma, there are some inexplicable bruises, which often appear for no reason and disappear inexplicably. Using the method of dealing with trauma to remove blood stasis may be very effective or completely ineffective, and this place may disappear. That place came out. These bruises may be caused by local microvascular thrombosis, so it is best to seek medical advice to confirm the cause, so as not to delay the diagnosis and treatment of the root cause.
Extended data
pathological change
1, the local tissues and organs with congestion are swollen due to hematocele. When it occurs on the body surface, due to the decrease of microcirculation perfusion, the content of oxygenated hemoglobin in blood decreases and the content of reduced hemoglobin increases, and the local skin is purple-blue, which is called cyanosis. Due to local blood stasis and telangiectasia, heat dissipation increases and body surface temperature decreases. Microscopically, local venules and capillaries dilate and excessive red blood cells accumulate.
2. Capillary congestion leads to the increase of hydrostatic pressure and hypoxia, and its permeability increases. Water, salt and a small amount of protein can leak out, and the leaked liquid stays in the tissue and causes congestive edema. Leakage can also accumulate in the serous cavity, causing pleural effusion, ascites and pericardial effusion.
3, capillary permeability further increase or rupture, causing red blood cell leakage, forming a small focal bleeding, called congestive bleeding. Red blood cell fragments in the bleeding focus are swallowed by phagocytes, hemoglobin is decomposed by lysosomal enzymes, and hemosiderin precipitates accumulate in the cytoplasm of phagocytes, which is called hemosiderin cells.
result
1, the consequences of congestion depend on the nature of organs or tissues, the degree and time of congestion and other factors. Short-term congestion has slight consequences, while long-term congestion has more serious consequences.
2. Long-term congestion, also known as chronic congestion, leads to atrophy, degeneration and even death of parenchymal cells due to local tissue hypoxia, insufficient supply of nutrients and accumulation and stimulation of metabolic intermediates. The proliferation of interstitial fibrous tissue, coupled with the collagenization of reticular fibers in the tissue, gradually hardened the organs, forming congestion and sclerosis.
