hemostasis
Pronunciation: hee-moh-STAY-sis
Achievement and maintenance of bleeding control during surgical procedures.
Full Definition
The process of stopping bleeding and maintaining blood vessel integrity during surgery through various mechanical, thermal, and chemical methods. Surgical hemostasis involves techniques including direct pressure, cautery, ligation, clips, and topical agents. Effective hemostasis is crucial for visualization during surgery and prevention of post-operative bleeding complications. Methods must balance bleeding control with tissue preservation to avoid thermal injury or ischemia. Modern electrosurgical devices provide precise hemostasis with minimal collateral damage when used appropriately.
Usage
Usage note: American spelling uses 'hemostasis'; British may use 'haemostasis'.
