A 3.6-fold longer length of hospital stay
What is the concern regarding enteral feeding in patients on ECMO?
Theoretical risk of increasing intestinal ischemia or bacterial translocation
What was the outcome of the retrospective study comparing EN to PN in pediatric ECMO patients?
EN was well-tolerated and without complication
What is the nutritional issue that neonates on ECMO support may experience beyond discharge?
All of the above
What is the recommended protein intake for neonates on ECMO support?
3 g/kg/d
What is the goal of protein provision in neonates on ECMO support?
To promote nitrogen balance and optimize growth
What is the consequence of negative protein balance in neonates on ECMO support?
All of the above
What is the recommended energy intake for neonates on ECMO support?
100-120 kcal/kg/d
Why is excess protein administration not recommended in neonates on ECMO support?
It can cause toxicity, particularly in patients with marginal renal or hepatic function
What is the consequence of excess calorie administration in neonates on ECMO support?
Increased carbon dioxide production with exacerbation of respiratory failure
When should enteral feedings be initiated in neonates on ECMO support?
When the patient has clinically stabilized
What is the effect of insulin infusion on protein balance in neonates on ECMO support?
It decreases protein catabolism
What is the significance of measuring nitrogen balance in neonates on ECMO support?
It measures nitrogen balance, which is a surrogate for protein balance
Study Notes
Extracorporeal Membrane Oxygenation (ECMO)
- ECMO is a modified heart-lung machine used in cases of profound cardiorespiratory failure.
- It has been used successfully in pediatric and adult applications, with the most frequent indication being neonatal respiratory failure.
- Common conditions that require ECMO include persistent pulmonary hypertension, congenital diaphragmatic hernia, congenital heart disease, and meconium aspiration.
Nutritional and Metabolic Burden in ECMO Patients
- ECMO patients have high rates of protein catabolism, with neonates demonstrating some of the highest rates reported.
- ECMO does not provide a "metabolic rest," and nutritional support is crucial to enhance growth and development.
Nutrition Support in ECMO Patients
- Nutrition support should be initiated expeditiously in neonates treated with ECMO, with a goal of 100-120 kcal/kg/d and protein up to 3 g/kg/d.
- Neonates on ECMO have protein requirements of up to 3 g/kg/d, with a goal of promoting nitrogen balance and optimizing growth and development.
- Energy requirements in neonates treated with ECMO are equivalent to healthy subjects, with a goal of 100-120 kcal/kg/d.
Enteral Feedings in ECMO Patients
- Enteral feedings should be initiated when the patient on ECMO has clinically stabilized, with caution advised prior to starting EN in patients who have not yet stabilized.
- Enteral nutrition (EN) is generally well-tolerated in ECMO patients, despite intestinal dysfunction, and may be beneficial when provided in addition to PN support.
- Neonates who have slow tolerance to EN have a longer length of hospital stay than those who are feeding optimally.
