Hemostasis

The arrest of bleeding, either physiologically, surgically, or mechanically.


The process which spontaneously arrests the flow of blood from vessels carrying blood under pressure. It is accomplished by contraction of the vessels, adhesion and aggregation of formed blood elements, and the process of blood or plasma coagulation.


The condition of controlled bleeding.


Stopping hemorrhage.


Naturally through the blood coagulation process, mechanically (e.g., with surgical clamps) or chemically (e.g., with drugs).


The process of stopping bleeding after an injury, either by surgery or by the body’s own blood clotting process. Bleeding can be arterial (from an artery) or venous (from a vein). There may also be minor bleeding from capillaries. Physicians recommend emergency medical attention for any case of severe bleeding. To prevent shock following an injury, the person must be kept warm and covered and lie down with his or her feet slightly elevated (unless there is a severe head, back, or leg injury). Sterile dressings and steady, firm, direct pressure should be applied to the wound.


The arrest of bleeding, involving the physiological processes of blood coagulation and the contraction of damaged blood vessels. The term is also applied to various surgical procedures (for example the application of ligatures or diathermy to cut vessels) used to stop bleeding.
