Comparison of Central and Peripheral Extracorporeal Membrane Oxygenation Cannulation Strategies in Postcardiotomy Shock
Authors' conclusion
Central and peripheral ECMO cannulation showed no significant differences in in-hospital mortality or major complications.
Study context
- Population
- Adults receiving extracorporeal membrane oxygenation (ECMO) for failure to wean from CPB or cardiogenic shock or cardiac arrest <24 hours after weaning from CPB, tertiary academic center, 2010–2023
- Participants
- 241 vs 78
- Exposure
- Central vs peripheral ECMO cannulation
- Centraln = 241reference
- Peripheraln = 78
- Outcome
- In-hospital mortality, bleeding requiring reoperation, stroke, limb ischemia, mechanical ventilation >7 days, and sepsis
Methodological detailssingle-centre, stabilized inverse probability of treatment weighting (propensity scores)
- Single-centre
- Stabilized inverse probability of treatment weighting (propensity scores)
Main finding
As reported in the abstract
In-hospital mortality
- In-hospital mortality 49.8% v 44.5% after propensity score weighting (abstract does not state which group each value belongs to); no significant difference
- No significant differences in the other primary outcomes (bleeding requiring reoperation, stroke, limb ischemia, mechanical ventilation >7 days, sepsis)
- Central vs Peripheral: P = 0.416
- Stabilized inverse probability of treatment weighting based on propensity scores
Observational data: associations, not effects.
Further findings
Baseline differences (before weighting)
- Peripheral ECMO associated with higher left ventricular ejection fraction
- P = 0.016
- Peripheral ECMO associated with posttransplant indication
- P = 0.026
