The hypothesis that inadvertent IV injection is related to adverse events seems odd to me. I was explicitly taught not to aspirate for IM injections in nursing school. I don't think it's a widespread practice anymore (though I believe it used to be) and I have never seen anyone aspirate for a IM injection. Before we jump to this conclusion I'd like to see some evidence about the actual likelihood of an inadvertent IV injection.
My understanding—and I’m stating this partly because I think you can correct me if I’m wrong—is that they stopped teaching people to aspirate because it is uncomfortable for the patient and the consequences of an inadvertent IV injection were thought to be low. I agree that inadvertent IV injection is probably rare; myocarditis with mRNA vaccination is also super rare. I honestly don’t know what the recommendation for practice would be if this hypothesis turns out somehow to be correct. Aspirate in certain demographically at-risk patients?
