| Preoperative anxiety is one of the most common clinical problems in perioperative patients. Numerous studies have confirmed that preoperative anxiety is closely related to the occurrence of adverse events, such as insomnia, postoperative pain, postoperative nausea and vomiting and postoperative delirium. However, its mechanism is not completely clear, which may involve multiple systems dysfunctions. Appropriate intervention or treatment for preoperative anxiety will contribute to reduce the incidence of perioperative adverse events. In this paper, typical perioperative adverse events, such as insomnia, postoperative pain, postoperative nausea and vomiting, and postoperative delirium, were selected to review the relationship between preoperative anxiety and perioperative adverse events, their mechanisms and intervention strategies. |
