VSE: Evidence about vasopressin, steroid, and epinephrine
V-E: Evidence about vasopressin and epinephrine
S-E: Evidence about steroid and epinephrine
S: Theoretical basis for steroid in post-arrest shock
Summary of all evidence
Putting evidence into practice
In-hospital cardiac arrest (IHCA) vs. out-of-hospital cardiac arrest (OHCA)
European 2015 Guidelines
- VSE is the only pharmacotherapy that has ever been shown to improve survival with good neurologic outcome. The AHA/ACC weakly recommends VSE (Class IIb) for inpatient cardiac arrest.
- The addition of vasopressin alone to epinephrine has not improved outcomes, leading the AHA/ACC to recommend against adding vasopressin alone to epinephrine.
- In a context where VSE cannot be implemented, a reasonable approach might be to simply add 40 mg of methylprednisolone during CPR with epinephrine. The AHA/ACC weakly supports this, with a Class IIb recommendation to use steroid for out-of-hospital arrest.
- The occurrence of post-cardiac arrest shock is common, with some similarities to septic shock (i.e. excessive inflammation causing vasodilation). Stress-dose steroid may be considered for these patients.
- More evidence is needed, but in the interim it seems reasonable to utilize therapies where the benefit appears to outweigh the risks.
