Abstract:
The average age of the world's population is increasing rapidly, with those over 80 years of age the fastest growing subsection of older persons. Consequently, a higher proportion of those presenting for surgery in the future will be older, including greater numbers aged over 100 years. Management of postoperative pain in these patients can be complicated by factors such as age and disease-related changes in physiology, and disease-drug and drug-drug interactions. There are also variations in pain perception and ways in which pain should be assessed, including in patients with cognitive impairment. Alterations in pharmacokinetics and pharmacodynamics may influence drugs and techniques used for pain relief. The evidence-base for postoperative pain management in the older population remains limited. However, most commonly used analgesic regimens are suitable for older patients if adapted and titrated appropriately.
