• Conditions: Elective Surgery; Intravenous Anesthesia; Preoperative Anxiety

• Registration Number: NCT03162692
• Lead Sponsor: Xuzhou Medical University

Brief Summary

Preoperative anxiety is often described as an uncomfortable, tense unpleasant mood before surgery, an emotional response to a potential challenge or threat to reality. Data show that adult patients with preoperative anxiety rate of 30-40%. The main reason for the occurrence of patients for surgery, anesthesia and other factors of fear. Preoperative anxiety itself is not a mental illness, but studies have confirmed that the occurrence of preoperative anxiety and postoperative complications were positively correlated, and the existence of preoperative anxiety in patients with conventional postoperative analgesic effect is poor. At present, there are still few studies on the relationship between preoperative anxiety and postoperative complications and analgesia. At the same time, there is a lack of large sample size to study the incidence of preoperative anxiety and its related predictors.

Detailed Description

Surgical patients often have varying degrees of preoperative anxiety.The aim of this study was to determine the incidence of preoperative anxiety and related predictors, and to evaluate the effect of anxiety on anesthesia and postoperative pain and prognosis. The study also showed that prostaglandin, catecholamines, cortex Effects of alcohol and inflammatory cell level on postoperative pain in patients with preoperative anxiety.
