Types of fracture blisters
Two types of fracture blisters have been identified: clear fluid-filled and blood-filled. The blood-filled blisters have been shown histological to have complete separation of the dermis from the epidermis, whereas the clear fluid-filled blisters demonstrate partial epidermal separation of the epidermis from the underlying dermis, with a few scattered areas of retained epithelial cells on the dermis. It is believed that blood-filled blisters are the result of injury to the papillary vasculature, allowing blood to escape into the blister. These represent a more significant injury histological and clinically. Due to detachment of the epidermis from the underlying dermis, eventual necrosis of the epidermis often ensues. Edema and venous stasis resulting from the injury induce collapse and thrombosis of affected blood and lymphatic vessels, thus adding to circulatory compromise.
Fracture blisters may appear as early as six hours after injury or as late as three weeks after trauma. These blisters signify underlying soft tissue damage and may result in increased infection rates for both operatively and no operatively treated fractures. Treatment recommendations have consisted of benign neglect, debridement, aspiration and surgical delay until reepithelialization occurs. Fracture blisters are defined as skin bullae and blisters representing areas of epidermal necrosis with separation of the stratified squamous cell layer by edema fluid. Fractures blisters contain sterile fluid but demonstrate colonization with multiple organisms once ruptured. Bacterial colonization was shown to be present until reepithelialization. This coupled with the resultant epidermal necrosis and hypoxia. It leads to an increased susceptibility to wound infection and dehiscence that is double the overall complication rate compared to fractures void of blistering.
Watch for a skin infection while your blister is healing. Signs of a skin infection include increased pain, swelling, redness, or warmth, red streaks extending away from the blister, a discharge of pus or a honey-colored fluid, fever, swollen...
Blister on finger
A finger blister is a type of blister that forms when sub dermal tissues and blood vessels are damaged without piercing the skin. It consists of a pool of lymph, blood and other bodily fluids trapped beneath the skin. If punctured, it suppurates a...
Blister on lips
Blister on lips is also called as oral herpes lesion because it often appears right after you have a cold or fever. Before you can see a fever blister your lip will tingle in the area that the cold sore will break out in and after a few days a small...
Skin rash blisters are fluid-filled bumps that look like bubbles on the skin. Home blister treatment for this is often all that is needed for this type of blister. Other types of injuries to the skin may cause a blister, such as exposure to heat,...
A friction blister is a soft pocket of a raised skin filled with a clear fluid caused by irritation from continuous rubbing or pressure. Friction blisters generally occur on the feet, where tight or poor-fitting shoes can rub and irritate delicate...
Genital blisters are caused by the herpes simplex virus II (HSV-II). It is estimated that 1 million new cases occur each year in the U.S alone. The infection is transmitted during sexual intercourse or by other intimate contact with the genitals,...
Herpes is a contagious infection that's caused by the herpes simplex virus. One type of the virus - herpes simplex virus type 1 (HSV1) - can lead to cold sores around the mouth. An infection of herpes simplex virus type 2 (HSV2) can lead to genital...
Spider bite blisters
There are at least 50,000 spider species in the arachnid family. Spiders are defined as having eight jointed legs, no wings, no antennae and only two body sections: the thorax and the abdomen. Spiders spend their entire life span capturing and...
A cesarean section delivery is done to protect the newborn from getting a herpes simplex infection at birth. A mother can pass the herpes simplex virus to her newborn if she has a sore or blister present when the newborn passes through the vagina...
A brief outlook: The swelling of lips may be of different types depending upon the causes of their occurrence like swollen lips medically termed as Myxedema or Angioedema, lip inflammation known to be as Eczema or Glucagonoma and enlargements...
