If your point is that these drips typically cross over into induction of general anesthesia and deep sedation, then I tend to agree.
I like prop for certain procedures and believe that it should be part of the EP armamentarium. However, I feel like EPs are being poorly served by hospitals that make it available but restrict EP privileges to ASA “moderate sedation” which does not fit the reality of the typical ED patient who needs prop.
IMHO, prop (and similar barbiturate anesthetics) is often the ideal agent for proximal joint reductions that require complete relation that can only be achieved by deep sedation or even general anesthesia - for 1 minute. In these patients, you are best to give a single, larger dose of prop that is typically 1-1.5 mg/kg. However, in doing this the EP will often blow right through moderate sedation and land, at least for a minute or two, in deep sedation or even general anesthesia territory. As long as the EP is prepared for this and the period is brief, this is safe in the ED. By prepared, I mean the EP has pre-oxygenated the patient, has appropriate ETCO2 monitoring, and is physically positioned to support the patient when they briefly lose their airway and respiratory reflexes for a minute or two. The EP cannot be trying to simultaneously tug a leg, jaw thrust, and bag a patient when doing this - multiple operators are necessary.
Where EPs get into trouble is when they slowly “titrate” prop for longer procedures such as EGDs, or get roped into repeated reduction attempts by ortho residents who want every upper level to tug on a leg before waking their attending up to book an OR case. This is where EPs can and do rarely MJ a patient (I’ve seen 2 cases in 20 years of bad, bad outcomes from prop shenanigans). There are a lot of strategies to avoid this that depend on local environment, but a common starting place is recognizing when our colleagues are asking us to do something dumb because they or the hospital are too cheap to properly staff the anesthesia department.
