Preoperative anxiety: Clinical manifestations, evaluation and prevention

Preoperative anxiety consists of physiological and psychological discomfort that manifests itself at the possibility of a surgical intervention. When the anxiety is weak or moderate, it is considered to be an adaptive response to a potentially anxiety producing situation. Prior research has established that high levels of preoperative anxiety increase the risk for postoperative complications as well as emotional and behavioral difficulties. Despite these sometimes severe medical and psychological consequences, very little literature exists aimed at French health care workers on the subject. The goal of this article is to synthesize the existing knowledge on preoperative anxiety, including its clinical manifestations and methods of evaluation and prevention. (C) 2010 Elsevier Masson SAS.
