A 58-year-old man with a 15-year history of type 2 diabetes mellitus (HbA1c 8.2%) and hypertension (on amlodipine 5 mg daily, BP 138/86 mmHg) presents for elective laparoscopic cholecystectomy. He denies chest pain, dyspnea, or palpitations. His exercise tolerance is good—he walks 3 km daily without symptoms. Physical examination reveals no cardiac murmurs, normal lung auscultation, and no peripheral edema. ECG shows normal sinus rhythm with no ST changes. What is his ASA Physical Status classification?

Explanation

## ASA Physical Status Classification Overview **Key Point:** ASA classification is a subjective assessment of preoperative risk based on systemic disease, not surgical complexity or urgency. ### ASA Classification Criteria | ASA Class | Definition | Examples | |-----------|-----------|----------| | **I** | Healthy, no systemic disease | Healthy 25-year-old for minor surgery | | **II** | Mild systemic disease, no functional limitation | Well-controlled HTN, DM, mild obesity, age >60 | | **III** | Severe systemic disease with functional limitation | Poorly controlled DM, CAD, COPD, cirrhosis | | **IV** | Severe systemic disease that is a constant threat to life | Unstable angina, recent MI, sepsis, decompensated heart failure | | **E** | Emergency (suffix added to any class) | Acute abdomen, trauma, ruptured aneurysm | ### Analysis of This Patient 1. **Type 2 Diabetes:** HbA1c 8.2% indicates reasonable glycemic control (target <7% is ideal, but 8.2% is not poorly controlled). No mention of diabetic complications. 2. **Hypertension:** Well-controlled on monotherapy (BP 138/86 mmHg is acceptable preoperatively). 3. **Functional Status:** Excellent exercise tolerance (3 km daily walk without symptoms). 4. **Cardiac Workup:** Normal ECG, no anginal symptoms. 5. **No End-Organ Damage:** No mention of nephropathy, neuropathy, retinopathy, or cardiac events. **High-Yield:** A patient with **well-controlled chronic conditions** and **no functional limitation** is classified as **ASA II**, not ASA III. The presence of mild systemic disease (DM + HTN) alone, without complications or poor control, defines ASA II. **Clinical Pearl:** ASA II does NOT mean "high risk"—it simply acknowledges one or more mild systemic diseases. The vast majority of elective surgical patients are ASA II. **Tip:** Do not confuse ASA classification with surgical risk stratification (e.g., RCRI, POSSUM). ASA is purely about the patient's medical status, not the operation itself.
