hemostasis
Pronunciation: HEE-moh-STAY-sis
Achievement of bleeding control through physiological or surgical means during acute care procedures.
Full Definition
Hemostasis refers to the process of stopping bleeding through natural physiological mechanisms or surgical intervention. In acute care surgery, achieving adequate hemostasis is fundamental to successful outcomes and patient safety. Methods include direct pressure, electrocautery, suture ligation, hemostatic agents, and vascular clamping. The term encompasses both primary hemostasis (initial platelet plug formation) and secondary hemostasis (fibrin clot formation). Surgeons must document hemostatic techniques used and confirm adequate hemostasis before closure. Failed hemostasis may lead to postoperative bleeding, hematoma formation, or need for return to surgery.
Usage
Usage note: Do not confuse with homeostasis (physiological balance). British spelling uses 'haemostasis.'
