Methods: 100 pregnant women undergoing induced abortion were randomly divided into two groups: group M was manually controlled infusion of propofol. It was administrated propofol 2mg/ Kg by intravenous injection after disinfection, and administering 0.5& 1.0mg/Kg boluses according to the patient's needs;

方法100例孕妇分为两组：M组采用丙泊酚MCI，消毒后静注丙泊酚2mg／kg，术中有体动反应时追加0.5～1.0mg／kg；

The result showed that the mean released rate of copper, cobalt and selenium in the boluses were 7.33mg/ kg, 0.33 mg/ kg and 0.21mg/ kg, respectively.

试验结果，在体外模拟条件下，Cu、Co、Se释放速度分别为7.33、0.33和0.21mg／kg；

Methods: The timing boluses were performed in twenty cases and the parameters such as effective concentration threshold of renal artery were obtained by the time-density curve.

方法：20例行同层动态增强扫描，通过时间-密度曲线获得肾动脉的有效浓度阈值。
