Cardiac arrest & resuscitation
Clinical state transitions in shock-refractory ventricular fibrillation: an observational study
Study context
- Population
- Emergency medical services (EMS)-treated out-of-hospital cardiac arrest (OHCA) with refractory VF/pVT (initial VF/pVT with ≥3 consecutive defibrillation attempts), Victoria, Australia, 2010–2019
- Participants
- 3,018 participants
- Exposure
- Clinical state transitions in refractory VF/pVT OHCA
- Outcome
- Clinical state transitions and their association with clinical outcomes
Methodological detailsadjusted logistic regression, EMS-treated OHCA, Victoria, Australia, 2010–2019
- Adjusted logistic regression
- EMS-treated OHCA, Victoria, Australia, 2010–2019
Main finding
As reported in the abstract
Clinical state transition
Observational data: associations, not effects.
Further findings
Discharged alive
Discharged alive
- Significantly higher in ROSC vs PEA and asystole
Secondary VF/pVT
- Secondary VF/pVT occurred
- 41.7%
- Predictors: male gender, increased resuscitation duration, adrenaline before first clinical state transition
- Transition into ROSC associated with reduced odds; transition into PEA increased odds
Predictors of achieving ROSC
- Bystander- or EMS-witnessed arrest and bystander CPR
