A patient undergoes hemodialysis on Mondays and Thursdays. What is their ASA classification?
Show answer and explanation
Correct answer: D. ASA IV
End-stage renal disease (ESRD) requiring hemodialysis = ASA IV — severe systemic disease that is a constant threat to life. ESRD involves multiple-organ complications (cardiovascular, hematological, metabolic, immune), requiring life-sustaining dialysis. Dental appointments are ideally scheduled the DAY AFTER dialysis (heparin cleared, optimal fluid/electrolyte status).
- A. ❌ ASA I = healthy patient with no systemic disease.
- B. ❌ ASA II = mild, well-controlled systemic disease with no functional limitation.
- C. ❌ ASA III = severe systemic disease with functional limitation — ESRD on dialysis exceeds this.
- D. ✅ ASA IV = severe systemic disease that is a constant threat to life — ESRD requiring dialysis qualifies.
