Abstract:
Three different dosages (0.25, 0.35, and 0.45 mg/kg) of rectally administered midazolam were compared with each other and with placebo for preanesthetic medication in children undergoing dental extractions. Eighty patients between the ages of 2 and 10 years were randomly allocated into four groups in this double-blind study. The results from this trial show that 30 minutes after rectal administration of all doses of midazolam, good anxiolysis, sedation, and cooperation were obtained in most patients. A high prevalence (23%) of disinhibition reactions was observed, particularly in the 0.45 mg/kg group. For this reason, 0.25 or 0.35 mg/kg appears to be the dose of choice when rectal midazolam is used for premedication in children.
