Educational Pearls:
Can opioids cause cardiac arrest?
-
Opioids can cause respiratory suppression and the subsequent low oxygen levels can lead to arrhythmias and eventually cardiac arrest.
-
In 2023, 17% of out-of-hospital cardiac arrests (OHCA) were attributable to opioids.
Given that this is a rising cause of cardiac arrest, should we just treat all cardiac arrest with naloxone (Narcan)?
-
Naloxone is correlated with an increased chance of return of spontaneous circulation (ROSC)
-
Additionally, a wide variety of individuals can be exposed to opioids and therefore opioid overdose should be considered in all cases of OHCA
But does naloxone improve neurologic outcomes?
-
Yes, naloxone, especially when given early on in the resuscitation can improve neuro outcomes
What is the dose?
-
2-4 mg IN/IV depending on access.
-
High suspicion for opioid overdose consider going with an even higher dose such as 4-8 mg IN/IV
