hemostasis
Pronunciation: hee-moh-STAY-sis
Achievement of bleeding control through physiological or surgical means during and after cardiovascular procedures.
Full Definition
Hemostasis refers to the process of stopping bleeding through various mechanisms including vasoconstriction, platelet aggregation, and coagulation cascade activation. In cardiovascular surgery, achieving adequate hemostasis is critical given the use of anticoagulation and extensive tissue dissection. Surgical hemostasis may involve electrocautery, suture ligation, topical agents, or mechanical compression to ensure bleeding control before closure.
Usage
Usage note: Distinguish from 'homeostasis' (physiological balance); context usually clarifies meaning.
