Introduction

  • Definition: geriatric = age >0.75 of expected life span for breed.
  • In general, anesthetic risk increases because old animals have a decreased ability to compensate for the physiological stresses of general anesthesia and surgery.
  • Complications may develop rapidly.
  • There may be concurrent disease that has not yet been recognized.
  • Physiologic and health status are more important than chronological age.
  • Geriatric does not necessarily mean ill. Many geriatric cats have good general health.
