Does subclavian vein cannulation improve safety or reduce complications in patients supported with peripheral VV ECMO compared to non-SCV sites?
Subclavian vein cannulation is a safe and viable alternative for venovenous ECMO access, with complication rates comparable to other sites.
OBJECTIVE: Venovenous (VV) extracorporeal membrane oxygenation (ECMO) cannulation may pose venous access challenges. Subclavian vein (SCV) cannulation is an alternative site. This study hypothesizes that SCV access is a safe alternative in VV ECMO. METHODS: This is a single-center, retrospective study of peripheral VV ECMO that was stratified by SCV cannulation. Each site was considered as a separate cannulation event. Descriptive statistics, groupwise comparisons, and mixed-effects logistic regression were used. Primary endpoints included cannulation-specific complications and ECMO-related adverse events. RESULTS: < 0.001) when compared with all non-SCV sites. Mixed-effects logistic regression showed no site-related differences in adverse events or complication rates. CONCLUSIONS: Between the SCV and non-SCV groups, there was no difference in site-related adverse events or complications. This study supports the use of SCV cannulation as a viable alternative in patients supported with VV ECMO.
