Response to intravenous midazolam sedation in general dental practice

The object of this study was to grade the response of patients undergoing a variety of dental procedures with the aid of intravenous midazolam sedation in general dental practice and to explore any relationships between the patients preoperative anxiety assessment and the clinician's assessment of co-operation whilst under sedation. One hundred consecutive patients aged between 18 and 58 years (mean 32 years; sd 10 years) and in ASA Class I or II were prospectively studied. Results showed that despite attempts to grade patient's behaviour it was not possible to reliably predict patient's responses under intravenous sedation. In addition to these findings, the great individual variation in sensitivity to midazolam was confirmed.
