Higher cumulative sedative exposure can reflect both treatment and the severity or duration of critical illness.
The prospective cohort assessed ventilated patients in five Peruvian ICUs. Deep sedation was common, and higher cumulative benzodiazepine exposure was associated with higher ninety-day mortality. The reported dose comparison contrasted the seventy-fifth with the twenty-fifth percentile, rather than each additional milligram.
Treatment was not randomized, and the analysis did not fully account for the primary illness when evaluating practice. Longer or more severe illness can affect both dose accumulation and outcome. Associations involving other medicines likewise cannot establish protection or harm causally.
For testimony, state the exact dose contrast and distinguish cumulative exposure from a toxic concentration. Examine sedation targets, illness trajectory and treatment duration. The source supports scrutiny of sedation practice but cannot quantify the mortality caused by a benzodiazepine in one patient.
