hemostasis
Pronunciation: HEE-moh-stay-sis
The process of controlling bleeding during and after surgical procedures.
Full Definition
Hemostasis in cardiothoracic surgery involves achieving and maintaining blood clotting to prevent excessive bleeding. This process is particularly challenging due to the use of anticoagulation during cardiopulmonary bypass and the extensive surgical dissection involved. Methods include mechanical compression, electrocautery, topical hemostatic agents, and reversal of anticoagulation with protamine sulfate. Effective hemostasis is crucial to prevent postoperative bleeding complications, cardiac tamponade, and the need for surgical re-exploration.
Usage
Usage note: Do not confuse with homeostasis (physiological balance).
