Prehospital flumazenil: 69 doses, no seizures
Prehospital Flumazenil: Five-Year Review of Use, Indications, Outcomes, and Adverse Events in Suspected Benzodiazepine Overdose
The Western Journal of Emergency Medicine · 2026-07-31 · Added 22 October 2026
A five-year Kansas review of 69 prehospital flumazenil administrations for suspected benzodiazepine overdose found clinical improvement with no seizures or adverse events recorded, even where possible contraindications existed.
- Study type
- Cohort
- Design
- Retrospective observational cohort
- Participants
- 69 prehospital flumazenil administrations over five years
- Main finding
- No seizures or adverse events were associated with flumazenil use (0/69; 95% CI 0–4.3%), with GCS improvement in the treated cases
- Caveat
- A tiny retrospective sample with a confidence interval wide enough to hide a real 4% adverse-event rate
- Bottom line
- Context only
Why it matters in Australia (Medium relevance). No Australian ambulance service carries flumazenil, so adoption would need a guideline change — the value here is challenging the reflex that the antidote is too risky for the road.
Learning goal
Weigh the risks and benefits of benzodiazepine reversal in overdose, given flumazenil is not carried by Australian services.

Ice-water immersion wins for drug hyperthermia
A systematic review of 71 studies (1,932 patients) comparing cooling methods for drug-induced (and exercise-induced) hyperthermia found ice-water and cold-water immersion fastest at ~0.16–0.17 °C/min and clearly superior to passive cooling.
