Nutritional considerations in the care of conjoined twins.

Conjoined twins represent an interesting nutritional challenge as nutrient delivery and absorption is greatly affected by anatomy and, therefore, unique to each twin pair. Nutritional support is essential to optimize growth and development in the neonatal period; however, very little data exists on the topic in this population. Conjoined twins require individualized nutritional assessment that focuses on the interaction between the metabolic rate, nutrient uptake, and nutrient delivery of each twin in the dyad. This report describes one center's experience with monitoring growth, establishing nutrient requirements, and determining substrate utilization in three sets of conjoined twins.
