• Status: Completed
• Trial end date: 2019-03-05
• Target enrollment: 0
• Participant gender: All

Summary

Pre-operative anxiety usually lead to increased anesthetics during the surgery. The precise sedative requirement which can keep adequate sedative state and avoid adverse effects caused by excessive drugs still needs further study. Therefore, our purpose was to confirm the sedative effect of butorphanol and to explore the relationship between pre-operative anxiety and intra-operative butorphanol requirement to evaluate the precise sedative requirement which can keep adequate sedation for patients by pre-operative anxiety score.
