Read the first 6 ECMO Indications & Patient Selection flashcards as text
Which pediatric condition most commonly requires VA ECMO support?
Answer: Congenital heart disease post-surgery
Congenital heart disease following surgical repair is the most common indication for VA ECMO in the pediatric population.
The SAVE score is used to predict survival in which ECMO population?
Answer: Adults on VA ECMO for refractory cardiogenic shock
The SAVE (Survival After Veno-Arterial ECMO) score predicts survival in adults with refractory cardiogenic shock on VA ECMO.
Persistent pulmonary hypertension of the newborn (PPHN) refractory to iNO is an indication for which ECMO modality?
Answer: VV ECMO if cardiac function is preserved
VV ECMO is preferred for PPHN when cardiac function is preserved, reserving VA ECMO for cases with concurrent cardiac failure.
Which pre-ECMO factor is associated with worse outcomes in respiratory ECMO candidates?
Answer: Mechanical ventilation > 7 days before cannulation
Prolonged mechanical ventilation before ECMO initiation (>7 days) is associated with significantly worse survival outcomes.
An awake ECMO strategy (ECMO without intubation) is primarily used to achieve what goal?
Answer: Avoid ventilator-induced lung injury and preserve respiratory muscle function
Awake ECMO avoids ventilator-induced lung injury and preserves diaphragmatic function, improving rehabilitation potential.
Which echocardiographic finding would most strongly support transitioning from VV to VA ECMO?
Answer: Severely reduced left ventricular systolic function with hemodynamic instability
Severely reduced LV systolic function causing hemodynamic instability requires cardiac support that only VA ECMO can provide.
