Drug Order in Rapid Sequence Intubation
Driver BE et al. Drug Order in Rapid Sequence Intubation.
Question they asked
Does drug order administration affect the time to successful first intubation attempt?
A secondary analysis of a previously published randomised trial(1), that compared bougie and stylet for intubation.
The primary outcome was intubation time. ie., the time from administration of first RSI drug, to removal of laryngoscope blade(end of attempt).
n = 562
153 patients had induction agent given first and 409 had neuromuscular blocker given first.
- 99% of the patients received Etomidate as the sedating age. Not everyone has etosidate.
- There was a large proportion receiving paralytic first. There was an obvious sample size difference.
- Apnoea time measured was not true time, but a surrogate marker.
The study concludes that there is a small decrease in total intubation time, however not statistically significant.
We certainly need more work on this. It sensibly appears that if the paralytic agent is given first followed by the sedating agent, it may decrease time to intubation, as compared with giving sedation and waiting and then giving paralytic.
