Emergence Agitation and Benzodiazepines: The Outcome Definition Shapes the Association
A postoperative observational study linked benzodiazepine premedication with an agitation-based outcome, leaving causal and diagnostic uncertainty.

What the study called emergence delirium
Patients with a Richmond Agitation-Sedation Scale score of at least +1 were classified as having emergence delirium/agitation. The reported overall frequency was 31.7%, and benzodiazepine premedication was among associated factors. Pain, anxiety, blood loss, and other characteristics were also relevant.
Agitation screening is not a complete delirium diagnosis
An activity-based score captures restlessness but does not by itself establish every feature of delirium. The observational design also leaves confounding by preoperative anxiety and treatment selection. Wide confidence intervals reflected limited precision, and follow-up outside the recovery unit was incomplete. The study therefore supports an association in a defined setting, not proof that premedication caused a particular delirium episode. In record review, describe the assessment instrument, timing, baseline status, pain, and medications before equating postoperative agitation with drug-induced delirium.
