Study Notes

Normal Control of Bleeding

Vascular phase: Blood vessels constrict to reduce blood flow to the injured area, reducing bleeding.
Platelet phase: Platelets aggregate at the injury site, forming a platelet plug that temporarily stops bleeding.

Blood Thinner Risks

Patients who receive blood thinners to prevent recurrent thrombosis are at increased risk of bleeding and bleeding complications.

Platelet Function

Primary function of platelets: Forming a platelet plug that temporarily stops bleeding.

Bleeding Risks

Factors that increase the risk of bleeding and bleeding complications: Use of blood thinners, impaired platelet function, and vascular damage.

Coagulation Phase

Coagulation phase of normal control of bleeding: Characterized by the formation of a fibrin clot that solidifies the platelet plug, permanently stopping bleeding.
