Two groups of 25 patients were sedated during neuroradiological investigation. The first group was sedated with fentanyl and midazolam while the other was given fentanyl and a two-stage infusion of propofol in a subanaesthetic dose. Both techniques resulted in satisfactory sedation and recovery, although those who received propofol were more likely to recall their journey from the X-ray department back to the ward. Sedation in both groups resulted in unacceptable PaO2 values in some patients which could subsequently be corrected by administration of supplementary oxygen.
两组各25名患者在神经放射学检查期间接受了镇静。第一组使用芬太尼和咪达唑仑进行镇静，而另一组则给予芬太尼和亚麻醉剂量的丙泊酚两阶段输注。两种技术均产生了令人满意的镇静和恢复效果，尽管接受丙泊酚的患者更有可能回忆起从X光科室返回病房的过程。两组的镇静在一些患者中导致了不可接受的动脉血氧分压（PaO2）值，随后可通过补充氧气予以纠正。
