Anesthetic agents, like lidocaine, that target sodium channels are widely used in the emergency department for topical and local anesthesia. Lidocaine is a local anesthetic agent with analgesic, anti-hyperalgesic, and anti-inflammatory properties. It has a short half-life (60 to 120 minutes) with often predictable adverse effects.
It has been suggested that IV lidocaine could be an alternative for pain control instead of opioids or NSAIDs when these other treatment modalities have been ineffective or associated with adverse effects.
IV lidocaine for the treatment of renal colic was covered in a recent “Skeptics’ Guide to Emergency Medicine” column (May 2018). The bottom line from that was that the study reviewed “does not provide good evidence for using lidocaine to treat patients presenting to the emergency department with renal colic.”| ← Previous | | | Next → | Single Page
