This research aims to understand how cannula configurations affect recirculation during veno-venous ECMO.
Assess recirculation fraction using a saturations-based formula in 24 patients
Collect relevant factors during recirculation assessment
Perform univariate and multivariate regression to evaluate clinical outcomes
Recirculation was non-significantly lower in femoro-jugular cannulation compared to femoro-femoral configurations
No significant differences in clinical outcomes were found between cannula configurations
Higher rates of tracheostomy and awake ECMO were noted with femoro-jugular cannulation.
