Dementia, the need for care or even death - an operation can be very dangerous, especially in old age. The most common cause are side effects of anesthesia. Gentler anesthesia procedures and drugs are now supposed to reduce the risk.
And every tenth person over the age of 65 dies sooner or later as a result of their surgery. This is the result of a new study. The risk is less the procedure itself, but the anesthesia, says Itay Bentov, professor of anesthesiology at the University of Washington. Because older people react differently to narcotics than the average adult.
The most common sequelae fall into two categories: On the one hand, there is what is known as postoperative delirium, when patients wake up confused. The symptoms, which are mostly temporary, vary between anxiety and aggressiveness, apathy and hallucinations. Such a continuity syndrome is also dangerous because it is associated with an increased risk of dementia and the need for care.
Postoperative cognitive dysfunction or POCD is less common, more difficult to diagnose and usually permanent. It manifests itself through a subtle decline in cognitive performance and is sometimes accompanied by a change in personality.
