ABSTRACT
Objective To investigate the correlation between preoperative anxiety and intraoperative anesthetic requirements,and to determine the proper anxiety evaluation scale.Methods Sixty ASA I patients undergoing knee arthroscopy were enrolled.The anxiety level of the patients was assessed by using the State-Trait Anxiety Inventory(STAI),Zung Self-Rating Anxiety Scale(SAS),and Visual Analogue Scale(VAS) 30 min before the surgery.The low frequency(LF) and low frequency/high frequency(LF/HF) of the heart rate variability were recorded before the surgery.Target controlled infusion(TCI) of propofol was started to provide a blood concentration of 1.5 ?g/ml,and was increased by 0.5 ?g/ml every 30 s until OAA/S value reached 4,which was defined as the point of consciousness loss.BIS value and propofol requirements were recorded.TCI of propofol was maintained for 30 min to keep a BIS value at 50,LF and LF/HF of heart rate variability and maintenance dose of propofol were recorded during this period.Results Propofol requirements at the point of consciousness loss were significantly liner correlated with the SAI,TAI,and Zung scores,as well as LF and LF/HF(r=0.362,0.285,0.315,0.274,0.411,P
