Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
A hemorrhagic infarct is determined when hemorrhage is present around an area of infarction. Simply stated, an infarction is an area of dead tissue or necrosis. [1] When blood escapes outside of the vessel (extravasation) and re-perfuses back into the tissue surrounding the infarction, the infarction is then termed a hemorrhagic infarct (infarction). [1]
The type of wound (incision, laceration, puncture, etc.) has a major effect on the way a wound is managed, as does the area of the body affected and presence of any foreign objects in the wound. A serious wound or any complication may require a call to emergency medical services. Any wound requires being disinfected after it stops bleeding.
Coagulopathy (also called a bleeding disorder) is a condition in which the blood's ability to coagulate (form clots) is impaired. [1] This condition can cause a tendency toward prolonged or excessive bleeding ( bleeding diathesis ), which may occur spontaneously or following an injury or medical and dental procedures.
Bleeding is caused by the generation of fibrinogen degradation products which interfere with regular fibrin polymerization and inhibit platelet aggregation. Moreover, plasmin which is formed in excess in hyperfibrinolysis can proteolytically activate or inactivate many plasmatic or cellular proteins involved in hemostasis.
Treatment was initially limited to aspirin and warfarin, but the 1990s saw the introduction of a number of agents that could provide anticoagulation without a risk of recurrent HIT. [4] Older terminology distinguishes between two forms of heparin-induced thrombocytopenia: type 1 (mild, nonimmune mediated and self-limiting fall in platelet count ...
Warfarin acts by inhibiting the production of Vitamin K in the gut. Vitamin K is required for the production of the clotting factors, II, VII, IX, and X in the liver. One of the most common causes of warfarin-related bleeding is taking antibiotics. The gut bacteria make vitamin K and are killed by antibiotics.
Warfarin necrosis is a rare but severe complication of treatment with warfarin or related anticoagulants. [2] The typical patient appears to be an obese, middle aged woman (median age 54 years, male to female ratio 1:3). [1] [3]: 122–3 This drug eruption usually occurs between the third and tenth days of therapy with warfarin derivatives. [1]
