They are at higher risk of sleep disturbance due to medications, pain and a change in environment, which in turn can contribute to delirium, a type of confusion after surgery. In general, the older patient will have a longer recovery time than a younger patient and is expected to have more complications.

Age of the Patient
Age has an impact on recovery. The general rule is that younger patients bounce back faster after a procedure when compared to older patients having the same surgery. That said, a healthy older patient could certainly recover faster than a very ill young patient.
Some common health problems related to aging — increased blood pressure, clogged arteries, and heart and lung disease — may make it more likely that you'll experience side effects or complications during or after surgery. And, just being older sometimes can cause some distressing side effects.
The most common presentation of delirium in the elderly postoperative patient is a “quiet confusion” that is more pronounced in the evening—otherwise known as sundowning. An acute change in mental status, manifested as a fluctuating level of consciousness or a cognitive deficit, is also common.
According to Dr. Raskin, it takes longer for an older person's body to rid itself of the chemicals involved in anesthesia, which can prolong the negative effects of these drugs. Because of this, many seniors report feeling foggy, slow or downright confused for days, weeks or even months after a surgical procedure.
Post-operative delirium is the most common complication of surgery for older adults, according to the American Geriatric Society, affecting up to 50% of seniors. If not identified early and treated, post-operative delirium can lead to long-term health issues, including cognitive decline and functional decline.
Traditionally, the “elderly” are considered to be those persons age 65 and older.
Research suggests that older adults who are frail, have cognitive impairment, or other serious conditions such as heart disease have worse experiences with major surgery. Also, seniors in their 80s and 90s are at higher risk of things going wrong.
In general, the older patient will have a longer recovery time than a younger patient and is expected to have more complications. In short, the elderly surgery patient will require more support than a younger one, from both professional healthcare providers and other individuals in their family and social circles.
It is quite common to feel fatigued after surgery, regardless of whether it was a minor or major procedure. This is because your body expends a lot of energy afterward trying to heal. There is an immune response that kicks in, which can be physically draining as well.
"The body's capacity to repair the skin diminishes as we get older. There aren't as many growth factors and stem cells in the skin. Chronic disease, especially blood vessel disease, and malnutrition can also slow the healing process," says Dr.

Many people can return to normal activity 12 weeks after their procedure. It's important to avoid overdoing it — and to expect some good days along with some bad ones. Sometimes, full recovery from hip replacement surgery takes six months and up to a year.
According to data from the American Medical Association, many surgeons continue to practice beyond the “standard” retirement age of 65. As the baby boomer generation reaches retirement age, it is anticipated that an increasing number of these surgeons will continue to practice as well.
"Don't have a general anesthetic once you're 50 – it'll wipe out a quarter of your brain." Recent studies have found that general anesthesia when used on the elderly, can increase the risk of dementia and the development of neurodegenerative disorders like Parkinson's or Alzheimer's disease.
Due to the uncertainty about the effects of exposure to anesthesia in childhood, the U.S. Food and Drug Administration advises that elective (not mandatory for health) surgery and anesthesia be delayed until after 3 years of age when possible.
The United States' older adult population can thus, be divided into three life-stage subgroups: the young-old (approximately 65 to 74 years old), the middle-old (ages 75 to 84 years old), and the old-old (over age 85).
This report focuses on older Australians—generally those aged 65 and over, unless otherwise specified.
Post-operative delirium is delirium that happens after an older adult has an operation (surgery) and is the most common post-operative complication in older adults. Delirium can have many causes – for example, drugs, infection, electrolyte imbalance, and not being able to move around (immobilization).
