Comparison of Preemptive Versus Conventional Distal Perfusion in Peripheral VA-ECMO
Study Details
Study Description
Brief Summary
Peripheral VA-ECMO is widely used in refractory cardiogenic shock patients as a salvage therapy. In most cases, the femoral artery and vein are used for the vascular approach. Large cannulas are usually used for proper oxygenation, which may cause peripheral limb ischemia. Distal perfusion catheterization (DPC) at the ipsilateral arterial cannula site is recommended to prevent distal limb ischemia. However, there is no consensus on the proper timing of DPC and additional invasive procedures may cause complications during VA-ECMO support. In this analysis, the investigators compare the clinical outcomes of distal limb ischemia complications between the conventional DPC group (DPC at the time of limb ischemia sign) and the preemptive DPC group (DPC at the time of VA-ECMO application).

Experimental: Preemptive distal perfusion group Distal perfusion catheterization will be done within 1 hour after VA-ECMO application. |
Procedure: Distal perfusion catheterization
Distal perfusion catheterization will be done within 1 hour after the VA-ECMO application in the preemptive DPC group. The conventional DPC group will undergo distal perfusion catheterization at the time of limb ischemia sign.

Active Comparator: Conventional distal perfusion group The conventional group will undergo distal perfusion catheterization at the time of limb ischemia sign. |
