Objective:

To determine the degree of depression in elderly adults after surgery and its relation with the duration of anesthesia.

Method:

We conducted an observational, comparative, prospective and longitudinal study. We included 73 elderly adults aged 60 scheduled for different surgical procedures. Their degree of depression was evaluated prior to and after the surgery with the short version of the Yasavage Geriatric Depression Scale. They were classified according to the score: no depression (0-5), mild depression (6-9) and established depression (10-15). The relation of depression with anesthesia duration was determined. The sample size was calculated for proportions. Descriptive statistics were used as well as χ2 (p < 0.05).

Results:

In the first evaluation 47 patients (64%) were not depressed, 21 (29%) had mild depression and 5 (7%) had established depression. In the second evaluation, we found that 44 patients (60%) were not depressed, 21 (29%) had mild depression and 8 (11%) had established depression. The relation between depression and anesthesia duration was χ2 = 0.81.

Conclusions:

We did not establish a relation between depression and anesthesia duration in surgically intervened elderly adults.
