Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Ecchymoses also have a more diffuse border than other purpura. [14] A broader definition of ecchymosis is the escape of blood into the tissues from ruptured blood vessels. [ 15 ] [ 16 ] The term also applies to the subcutaneous discoloration resulting from seepage of blood within the injured tissue.
Europe is the only continent with more instances of non-colocalized than colocalized bloodletting. In a transmission chain experiment done on people living in the US through Amazon Mechanical Turk , stories about bloodletting in a non-affected area were much more likely to transition into stories about bloodletting being administered near the ...
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.

Evidence supports holding off on blood transfusions in those who have a hemoglobin greater than 7 to 8 g/dL and moderate bleeding, including in those with preexisting coronary artery disease. [7] [12] If the INR is greater than 1.5 to 1.8 correction with fresh frozen plasma or prothrombin complex may decrease mortality. [4]
An ecchymosis is a hematoma of the skin larger than 10 mm. [2] They may occur among and or within many areas such as skin and other organs , connective tissues , bone , joints and muscle . A collection of blood (or even a hemorrhage ) may be aggravated by anticoagulant medication (blood thinner).
Wounds naturally heal by themselves, but hunter-gatherers would have noticed several factors and certain herbal remedies would speed up or assist the process, especially if it was grievous. In ancient history , this was followed by the realisation of the necessity of hygiene and the halting of bleeding , where wound dressing techniques and ...
Subdural hematoma maybe less acute than epidural hematoma due to slower blood accumulation, but it still has the potential to cause brain herniation that may require surgical evacuation. [3] Clinical features depend on the site of injury and severity of injury. Patients may have a history of loss of consciousness but they recover and do not ...
