perioperative risk stratification (relative risk of non-cardiac surgeries)

Introduction

Perioperative risk stratification for non-cardiac procedures

• High risk (> 5% complications)
  • emergent major operations (especially in the elderly)
  • aortic & other major vascular procedures
  • peripheral vascular procedures
  • prolonged surgical procedures
    • large fluid shifts
    • significant blood loss

• Intermediate risk (1-5% complications)
  • carotid endarterectomy
  • head & neck procedures
  • intraperitoneal & intrathoracic procedures
  • orthopedic surgery
  • prostate surgery

• Low risk (< 1% complications)
  • endoscopic procedures
  • superficial procedures
  • cataract surgery d breast surgery

• American College of Cardiology/American Heart Association guidelines recommend adding functional status (expressed in METs) plus a validated clinical risk score to guide risk stratification
  • serum NT-proBNP alternative to functional status
