@ES The results were as follows:
@EN 1) Total patients over 60 years of age were 3392 cases, and these were subdivided into 54.9% male and 45.1% female patients. And then the most common age group for geriatric anesthesia was 60~64 years(36.5%).
2) There were 45.3%) in general surgery, 18.8% in urology and 14.4% in orthopedic department among the 3392 cases. And the most frequent site were 25.8% in upper abdominal field and 18.9% in lower abdominal field.

decreased
tendency according to age.
