[Development of operative therapy in a public hospital 1910 to 1980].

An analysis of the operation records for the years from 1910 to 1980 shows a considerable increase in the indication for surgical treatment. While the average age of the groups of patients does not increase in general, an increase in the number of patients operated on in higher age can be proved. This paper gives an outline of problems of preparation for operations, the application of narcosis techniques and postoperational care for these groups of patients.
