Summary
Orthopedic surgeries are considered to be discomfortable and the sense of fear and anxiety of
patients who already have preoperative anxiety may be aggravated by intraoperative
stimulation, which may contribute to postoperative complications. Previous studies have found
that high anxiety predicts increased sedative requirements. Therefore, the investigators
explored the relationship between anxiety and intraoperative butorphanol requirements and the
investigators evaluated the specific sedative requirement which can keep satisfactory
sedative state for patients by preoperative anxiety score
