8/4/2023 0 Comments Asa class![]() ![]() Tiret et al reported the perioperative complications to be related closely to physical status (ASA class I= 0.4/1000 IV & V = 9.6/1000) with emergency surgeries having even greater correlation 1/1000 in class Iincreasing to 26.5/1000 in class IV & V2. Cautionmust be applied when using risk assessment in individual patients.Īlthough the ASA classification was not designed for calculating the anaesthetric or surgical risk but many clinical studies used this classification for preducting patient outcome. No other preoperative risk assessment scheme has achieved the same widespread use.Ī method for risk assessment based on multivariate analysis from a large group of patients that can be prospectively validated at multiple institutions would be valuable, not only for mortality rate comparisons but also for patient counseling, research and hospital management. This classification is now used throughout the world to indicate physical status having become part of the routine shorthand in assessingpatients prior to surgery. Class VI A declared brain-dead patient whose organs are being removed for donor purposes. ![]() The ASA physical status scaleClass I A normally healthy individualClass II A patient with mild systemic diseaseClass III A patient with severe systemic disease that is not incapacitating Class IV A patient with incapacitating systemic disease that is a constant threat to life Class V A moribund patient who is not expected to survive 24 hour with or without operation. Initially six categories were described a seventh being added after the ASA published the classification. Instead the term physical state was adopted. The system was intended to describe the patient, and not the specific anaesthetic or surgical risk. The disease process whichpresent at the time of the surgical procedure, should be graded because itpredispose to risk stratification1.Īlthough the term operative risk was initially considered, this was deemed unsuitable because it was altered by the magnitude of the surgical procedure. And the physical status of a patient includes its airway anatomy. The ASA Physical Status Classification is a physical status classification at the time of the surgical procedure. This Committee had the task ofdevising a system for collection and tabulation of statistical data in anaesthesia. The concept of physical status classification was suggested in 1941 by a committee of the American Society of Anesthetists, the predecessor ofthe American Society of Anaesthesiologists. ![]()
