A comparison of two sedation techniques for neuroradiology.

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.
