What Is Normal Hemostasis

Hemostasis is the physiologic mechanism that stems bleeding after injury to the vasculature. Normal hemostasis depends on both cellular components and soluble plasma proteins. Circulating platelets adhere and aggregate at sites of blood vessel injury.

What is good hemostasis?

Physical agents (gelatin sponge) – Gelatin sponges have been indicated as great hemostatic devices. Once applied to a bleeding area, a gelatin sponge quickly stops or reduces the amount of bleeding present. These physical agents are mostly used in surgical settings as well as after surgery treatments.

What are the 4 stages of hemostasis?

The mechanism of hemostasis can divide into four stages. 1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.
