How does swollen after crural fracture return a responsibility?
summary
Unfortunately, some patients were injured, leading to fracture and hospitalization. They planned to arrange surgery after detumescence. Unexpectedly, many blisters appeared. In the heart very chagrin, today let me share with everybody after foot fracture edema how to return a responsibility?.
How does swollen after crural fracture return a responsibility?
First, when the fracture occurs, the local soft tissue (especially the muscle) is also damaged, resulting in swelling. Due to the limited elasticity of the skin, the skin becomes "tight" after swelling, the local pressure increases, the blood vessels and lymphatic vessels are compressed, and the resistance of blood flow backflow increases. In addition, the blood vessels are damaged, the capillary permeability increases, and the fluid exudation increases. The bleeding after the fracture makes the local pressure higher, and the exudate is in the epidermis Tension blisters were formed in the weak part of dermis.
Second, the appearance of blisters indicates that the soft tissue injury is serious. The more serious the injury, the more swelling and blisters. This not only increases the risk of wound infection, but also affects the normal operation and delays the treatment of fracture. Some scholars believe that the skin around blisters should not make incision as far as possible, because the incidence of skin necrosis and infection is very high.
Third: Blister skin is a good natural biological dressing. Retaining blister skin can significantly reduce pain and effectively prevent skin necrosis. The smaller vesicles can be absorbed by themselves; For large blisters, it is recommended to use sterile syringe to pump the liquid inside the blisters, but the blister skin should not be cut off. If the blister skin has been "rubbed off", the surface can be coated with sulfadiazine silver cream or MEBO.
matters needing attention
Raise the affected limb: the fracture site should be higher than the heart level. Timely reduction of fracture and good immobilization. Ice / cold compress: make microvascular constriction, reduce permeability, reduce bleeding and bleeding of damaged vessels. Drug treatment: including oral and intravenous drugs. Oral drugs such as weilitan sustained-release tablets, intravenous drugs are 20% mannitol β- Sodium aescinate, diuretic. The main effect is to eliminate the swelling of local tissue, some drugs have anti-inflammatory and improve blood circulation at the same time.
