We question the validity of this approach. We compared the two sedation regimens used in our general ICU in a trial structured to mimic clinical practice as closely as possible. Results Forty patients were randomised to intermittent diazepam or continuous midazolam and sedation monitored with hourly sedation scores 31 patients completed the study. Scores indicating undersedation were more common with diazepam P overall adequate sedation midazolam diazepam P . No patient exhibited inappropriately prolonged sedation. Cost was midazolam AUS h diazepam AUS h. Conclusion Both regimens produced rapid onset of acceptable sedation but undersedation appeared more common with the cheaper diazepam regimen. At least 140 patients should be studied to provide evidence applicable to the general ICU population. Used alone a sedation score may be an inappropriate outcome measure for a sedation trial.
