A pediatric ICU analysis associated even low benzodiazepine exposure with next-day delirium, without proving that every small dose causes delirium.
The secondary analysis used 10,644 patient-days from 1,006 children across seven PICUs. Higher previous-day benzodiazepine dose was associated with delirium, with an adjusted odds ratio of 1.12 per midazolam-equivalent mg/kg. A nonlinear model showed its steepest increase near the lowest exposure range. Dexmedetomidine and restraint use were also associated with delirium.
The parent mobility project was randomized, but individual sedative doses were not. Illness, agitation and changing treatment needs can confound dose associations. Modeled absence of a safe threshold does not establish inevitable injury or an experimentally verified causal threshold. Equivalent-dose conversions add further assumptions.
For pediatric review, identify the prior-day exposure, indication, baseline delirium risks and timing of assessments. Do not infer negligence from any nonzero dose or assume another sedative would necessarily eliminate risk. The paper supports cautious dose and outcome review, with patient-specific clinical justification remaining essential.
