Abstract
The World Health Organization defines healthy ageing as 'the process of developing and maintaining the functional ability that enables well-being in older age'. This functional ability is the characteristic of the individual's own physical and mental status influenced by the environmental and socio-economic factors. Preoperative preparation of the elderly patients includes functional assessment to identify preexisting cognitive impairment or cardio-pulmonary reserve, frailty, nutrition, polypharmacy and anti-coagulation issues. Intraoperative management includes anaesthetic mode and pharmacology, monitoring, intravenous fluid and transfusion management, lung protective ventilation and hypothermia. Postoperative checklist includes perioperative analgesia, postoperative delirium and cognitive dysfunction.
