异丙酚静脉注射后起效迅速,快速分布到外周组织,且清除快、停药后病人苏醒快[1]。近年来对异丙酚在小儿的药代学和药效学方面进行了深入研究,其有效性和安全性得到证实。异丙酚靶控输注(TCI)能维持效应室或血异丙酚浓度在有效的范围,可避免有效浓度的波动而带来的麻醉不全、术 Prompt onset of rapid intravenous propofol, rapid distribution to peripheral tissues, and cleared quickly, withdrawal of patients wake up fast [1]. In recent years, propofol in pediatric pharmacokinetics and pharmacodynamics conducted in-depth study, its effectiveness and safety confirmed. Propofol target-controlled infusion (TCI) to maintain the effect of room or blood concentration of propofol in the effective range, to avoid fluctuations in the effective concentration caused by anesthesia, surgery
