Episode notes
Pre-Hospital Pain Management Challenges
- Treating pain pre-hospitally is crucial, but challenging.
- Challenges include pain assessment and medication downsides (e.g., opioid risks, NSAID/acetaminophen limitations).
Ideal Pre-Hospital Analgesics
- Ideal pre-hospital analgesics should be safe, easy to use, and physician-free administrable.
- IVs are difficult in challenging settings, while intranasal medications have inconsistent dosing.
Inhaled Medications: Options and Downsides
- Two inhaled medications exist: nitrous oxide (Entinox) and methoxyflurane.
- Entinox has downsides: bulky tanks, hypoxia risk, cold-weather challenges.
