摘要: Objective: To determine predictors and behavioral outcomes of preoperative anxiety in children undergoing surgery. Design: A prospective, longitudinal study. Setting: university children's hospital. Participants: One hundred sixty-three children, 2 to 10 years age (and their parents), who underwent general anesthesia elective Main Outcome Measures: In the holding area, level child parents was determined using self-reported independent observational measures. At separation operating room, rated again. Postoperative responses were evaluated 3 times (at weeks, 6 months, 1 year). Results: multiple regression model (R =0.58, F=6.4, P =.007) revealed that older anxious parents, received low Emotionality, Activity, Sociability, Impulsivity (EASI) ratings for activity, with a history poor-quality medical encounters demonstrated higher levels area. similar =0.42, F=8.6, =.001) EASI previous hospitalization, not enrolled day care, did undergo premedication more at room. Overall, 54% exhibited some negative 2-week follow-up. Twenty percent continued demonstrate behavior changes 6-month follow-up, and, 7.3% these behaviors persisted 1-year Nightmares, anxiety, eating problems, increased fear physicians most common problems Multivariate analysis child's age, number siblings, immediate mother predicted later problems. Conclusions: Variables such as situational mother, temperament child, quality predict anxiety. Although develop relatively large young following surgery, magnitude is limited, long-term maladaptive only small minority. Arch Pediatr Adolesc Med. 1996;150:1238-1245
