A sequential dose-finding study estimated a remimazolam bolus associated with 90% prevention of rated emergence delirium. That model estimate is not a universal pediatric dose recommendation.
A narrow clinical setting
Xue and colleagues studied children aged two to twelve undergoing laparoscopic inguinal hernia repair with sevoflurane anesthesia. Fifty-six children were enrolled in the analyzed dose-finding sequence, which used a biased-coin up-and-down allocation method.
The estimated ED90 was 0.114 mg/kg, with a 95% confidence interval of 0.098–0.128. The total emergence-delirium incidence across the tested sequence was 14.3%. These figures describe the endpoint and accompanying anesthetic protocol.
How dose finding differs from a comparative trial
The design concentrates observations around a target response level. It does not supply the same evidence as a large randomized comparison against placebo or another sedative. An ED90 estimate also does not mark the boundary between safe and unsafe exposure.
No adverse events were observed within the tested range, but the small selected sample cannot exclude uncommon complications. Emergence ratings, procedure duration, and analgesic context further limit extrapolation.
Practical meaning
If the statistic is used in an expert report, attach the population, surgery, endpoint, and confidence interval. Do not apply it to different procedures or assume that a patient outside the estimate necessarily received an inadequate or excessive dose.
