The use of etomidate and rocuronium for rapid sequence intubation (RSI) results in a duration of paralysis that exceeds the duration of sedation. The primary objective of this study was to compare the number of analgosedative (AGS) interventions early versus late post-RSI, with this drug combination. The secondary objective was to descriptively assess time to first AGS intervention.

This was a retrospective cohort study conducted in an academic ED in the United States between January 2015 and June 2016. The study was conducted after a pharmacy-led education program. Consecutive adult patients who received the combination of etomidate and rocuronium for RSI were included. The primary outcome measure was the number of AGS interventions post-RSI. An AGS intervention was defined as initiation of an opioid or sedative, or a dose increase of an infusion rate. Interventions were categorized as early (0–30min post-RSI) or late (60–90min post-RSI).

The sample (n=108) had a mean age of 58±19years, and the majority was male (n=62, 57%). The mean rocuronium dose was 1.1±0.3mg/kg. There was a median of 2 interventions (IQR 1–3) that occurred early versus 0 interventions (IQR 0 to 1) that occurred late post-RSI (p<0.001). The median time to first AGS intervention was 7min (IQR 3 to 13min).

When rocuronium was used for RSI in the ED there was no delay in provision of post-intubation sedation or analgesia, after a pharmacy-led educational program.
