ANAESTHESIA AND SURGERY IN GERIATRIC PATIENTS

KEY POINTS
 :
 
(1) Advancing age is not in itself a contraindication to general anaesthesia or major surgery.
(2) Preoperative screening of old patients for the presence of subdisease or impaired organ function is necessary before anaesthesia or surgery.
(3) Anaesthetic doses should be based on lean body weight not actual body weight if the animal is obese.
(4) Generally, anaesthetic and other drug doses need to be reduced in ageing patients.
(5) Attempts must be made to avoid the development of hypothermia and hypotension during anaesthesia of old patients.
(6) Reduce exposure to known risk factors for acute organ failure, especially acute renal failure.
