Purpose

Purpose: This study aimed to find a quick and timely way to investigate the individual variation of efficacy of opioid analgesic in Chinese patients undergoing elective surgeries. Methods: 120 female patients receiving elective surgery under general anesthesia were recruited into this study. At the time of routine intravenous anesthetic induction we observe the efficacy of opioid analgesic including analgesic effect, effects on Narco-trend index, sedative effect, effects on respiratory system, and aslo effects on cardiovascular system.

Primary Outcome Measures:

Mean Pressure Pain Threshold [ Time Frame: 10 minutes after the procedure ]
According to the measurement of pressure pain threshold after intravenous injection of opioid analgesics
Mean Value of Narco-trend Index [ Time Frame: 10 minutes after the procedure ]
According to the measurement of Nacro-trend index after intravenous injection of opioid analgesics. Narco-trend index is from 0 to 100 which 0 represent deep sedation, and 100 represent waking state.

Secondary Outcome Measures:

Mean Arterial Pressure [ Time Frame: 10 minutes after the procedure ]
According to the measurement of mean arterial pressure before and after intravenous injection of opioid analgesics
Mean Heart Rate [ Time Frame: 10 minutes after the procedure ]
According to the measurement of heart rate before and after intravenous injection of opioid analgesics
Mean Respiratory Frequency [ Time Frame: 10 minutes after the procedure ]
According to the measurement of respiratory frequency after intravenous injection of opioid analgesics
