ASA classification
Pronunciation: ay-ess-ay klas-ih-fih-KAY-shun
American Society of Anesthesiologists physical status classification system for surgical risk assessment.
Full Definition
A standardized system for evaluating a patient's preoperative physical condition and anesthetic risk, ranging from ASA I (healthy patient) to ASA VI (brain-dead organ donor). The classification helps guide anesthetic management and surgical planning. ASA I and II patients are typically suitable for office-based oral surgery, while ASA III and higher may require hospital-based care or medical consultation. The system also includes an 'E' modifier for emergency procedures, which increases perioperative risk.
Usage
Usage note: Roman numerals (I-VI) are used, not Arabic numbers, in the classification system.
