Safety of local anesthetics in cervical nerve root injections: a narrative review

AbstractSevere neurological adverse events have been reported after fluoroscopically guided cervical nerve root injections. Particulate corticosteroids inadvertently injected intraarterially and iatrogenic vertebral artery trauma have been implicated in these outcomes. This has raised concern for the potential consequences of including local anesthetic with these injections. As a result, some providers have now discontinued the routine administration of local anesthetic with corticosteroid when performing cervical nerve root injections. At present, there is no consensus regarding whether the use of local anesthetic in this context is safe. Here, the current literature is synthesized into a narrative review aiming to clarify current perspectives of the safety of local anesthetics in cervical nerve root injections.
