Rapid Agitation Review Found a Speed–Adverse-Event Tradeoff Against Benzodiazepine Combinations

Faster sedation was the clearest comparative finding; it did not establish the best regimen for every emergency presentation.

What the supplied source reports

The systematic review identified three emergency-department studies: two randomized trials and one cohort. Ketamine achieved sedation sooner than haloperidol combined with a benzodiazepine in all three reports. Two studies also reported more adverse effects in the ketamine groups.

Limits of the evidence

The synthesis was qualitative, involved few studies and mixed observational with randomized evidence. The studies came from the United States and Canada. Differences in route, patient selection and sedation definitions constrain generalization, and the comparator was a combination rather than a benzodiazepine alone.

Implications for forensic interpretation

For a behavioral-emergency reconstruction, distinguish time to adequate control from respiratory complications, rescue treatment and recovery. Document co-intoxicants, physiological disturbance and monitoring. A shorter time to sedation can matter clinically without proving lower overall risk or identifying which component of a multi-drug regimen produced an adverse effect.
