[Changes in psychological features in patients for anesthesia and operation during perioperative period]

Abstract

The purpose of this study was to assess perioperative changes in psychological features of patients receiving anesthesia and operation. Anxiety level and desire for obtaining information were evaluated in 37 patients using the Amsterdam preoperative anxiety and information scale (APAIS) at three points: before and after the preanesthetic examination, and 3 to 5 days after the operation. Anxiety scale (4-20) and information scale (2-10) scores decreased postoperatively from 9.8 +/- 3.8 to 7.3 +/- 3.4 and from 6.1 +/- 2.1 to 4.1 +/- 1.9, respectively. There was a significant but weak correlation (rs = 0.35) between the anxiety scale and information scale before the preanesthetic examination. The postoperative information scale score correlated well with preoperative anxiety scale score (rs = 0.61), and this correlation was higher than with preoperative information scale score (rs = 0.37). When patients were divided into two subgroups, namely patients with (U, n = 12) or without (non-U, n = 25) an increase in postoperative information scale score, anxiety scale score before the preanesthetic examination tended to be higher and the postoperative anxiety scale score was significantly higher in the U group than in the non-U group. We conclude that we should provide more information to the patients who have higher anxiety scale score before the preanesthetic examination regardless of their degree of desire for information.
