Study Notes
ASA Classification System
- Developed by the American Society of Anesthesiologists to categorize patients' physical status before surgery.
- Provides insight into a patient's preoperative condition, independent of the surgical procedure planned.
- Does not indicate anesthesia or surgical risk.
ASA Class I
- Represents a normal, healthy patient.
- No organic, physiological, biochemical, or psychiatric disturbances.
- Example: A healthy individual who does not smoke and consumes minimal alcohol.
ASA Class II
- Describes a patient with mild to moderate systemic disturbance.
- Condition includes mild diseases with no significant functional limitations.
- Examples: Current smokers, social alcohol drinkers, pregnant women, individuals with obesity (BMI 30-40), well-controlled diabetes, mild hypertension, mild lung disease.
ASA Class III
- Indicates severe systemic disturbances that limit activity.
- Includes patients with substantive functional limitations and one or more moderate to severe diseases.
- Examples: Poorly controlled diabetes or hypertension, chronic obstructive pulmonary disease (COPD), morbid obesity (BMI > 40), active hepatitis, alcohol dependence, implanted pacemaker, moderate reduction of ejection fraction, end-stage renal disease undergoing dialysis, and a history of myocardial infarction, cerebrovascular accident, transient ischemic attack, or coronary artery disease.
ASA Class IV
- Refers to a severe systemic disturbance posing a constant threat to life.
- Patients have severe systemic diseases that require vigilant monitoring.
- Examples: Recent history of myocardial infarction, cerebrovascular accident, transient ischemic attack, coronary artery disease, ongoing cardiac ischemia, severe valve dysfunction, significant reduction in ejection fraction, sepsis, disseminated intravascular coagulation (DIC), acute respiratory distress syndrome (ARDS), or end-stage renal disease not undergoing dialysis.
ASA Class V
- Describes moribund patients requiring surgery as a resuscitative measure, with little chance of survival.
- Indicates patients whose survival is not expected without surgical intervention.
- Examples: Situations involving ruptured abdominal or thoracic aneurysms, massive trauma, intracranial bleeding with mass effect, ischemic bowel in the context of significant cardiac issues, or multiple organ/system dysfunction.
