Surgical procedures in patients during the tenth decade of life

The purpose of this study was to determine the outcome of major surgical procedures in patients 90 years of age or older. The records of 46 patients in this age group who underwent surgical procedures were reviewed to determine the outcome and the postoperative quality of life. Overall, the perioperative mortality was 20%. Mortality was not influenced by such risk factors as diabetes mellitus, chronic obstructive pulmonary disease, renal failure, quantity of blood loss, duration of procedure, or total number of hospital days. However, patients with heart disease had a significantly higher mortality rate (78%). Overall, 39% of the patients experienced a subjective deterioration in their mental status after surgery. Of those patients who were ambulatory before surgery, 73% were ambulatory after surgery. Although this study indicates that the perioperative mortality is high and mental status changes frequent in this very elderly age group, the quality of life and longevity of the majority of these patients are good, and vigorous surgical intervention appears warranted.
