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；
