✍️ Sample ECMO Questions & Answers

1. The ELSO (Extracorporeal Life Support Organization) registry reports the highest survival rates among which ECMO patient group?
Neonatal respiratory ECMO

Neonatal respiratory ECMO has the best outcomes, with survival to discharge approximately 73% according to ELSO registry data.

2. A neonate on femoral VA-ECMO develops progressive ipsilateral lower extremity ischemia. The most appropriate intervention is:
Insert a distal perfusion catheter into the superficial femoral artery

A distal perfusion catheter (DPC) inserted antegrade into the superficial femoral artery restores distal limb perfusion while maintaining ECMO support.

3. The primary goal of ECMO support in pediatric myocarditis is:
Bridging to myocardial recovery or cardiac transplantation

Myocarditis can cause fulminant cardiac failure, and ECMO provides hemodynamic support while awaiting spontaneous recovery or listing for transplantation.

4. What is the minimum gestational age generally accepted as a criterion for neonatal ECMO candidacy?
34 weeks

Most centers require ≥34 weeks gestational age because premature neonates face prohibitively high rates of intracranial hemorrhage on ECMO anticoagulation.

5. How does ECMO most significantly alter zinc and selenium homeostasis?
Adsorption of trace elements onto the circuit and oxygenator leads to reduced plasma levels

Selenium and zinc are adsorbed onto circuit components and consumed by the inflammatory response during ECMO, leading to clinically significant depletion requiring supplementation.

6. Fentanyl is significantly sequestered in ECMO circuits primarily because it is:
Highly lipophilic with high protein binding

Fentanyl's high lipophilicity and protein binding cause it to adsorb onto ECMO tubing and the oxygenator, reducing effective plasma concentrations.
