<abstract xmlns="http://www.w3.org/1999/xhtml"><p> In the past two decades, the demographic crisis in Bulgaria has been widely debated. According to the National Statistical Institute (NSI), the proportion of people aged 65 and over is increasing, despite the general population decline in the country. To investigate whether the age structure of patients operated on has changed during the past 10 years and assess the need to reorganize the training of anesthetists,aretrospective study in the anesthesia electronic database of the University Hospital in Rouse was carried out. The data of anesthesia performed by anesthesiologists in 2005, 2010 and 2015 in patients aged 65 and over were summarized.
