ELBW
Also written as: ELBW — Extremely Low Birth Weight
Extremely low birth weight - birth weight less than 1000 grams (2.2 pounds).
Full Definition
ELBW stands for extremely low birth weight, a classification used for infants born weighing less than 1000 grams or approximately 2.2 pounds. These infants represent the most vulnerable population in neonatal intensive care, often born before 28 weeks gestation. ELBW infants face significant risks including respiratory failure, intraventricular hemorrhage, necrotizing enterocolitis, and long-term developmental delays. The survival rates for ELBW infants have improved dramatically over recent decades due to advances in surfactant therapy, gentle ventilation strategies, and improved nutritional management. These infants typically require prolonged NICU stays, often until their original due date or beyond.
