Full Definition
Very Low Birth Weight (VLBW) is a classification for infants who weigh less than 1,500 grams at birth, regardless of gestational age. These infants face significant medical challenges due to their size and often premature organ development. VLBW infants typically require intensive medical care in a NICU and are at higher risk for complications such as respiratory distress, feeding difficulties, temperature instability, and long-term developmental issues. The survival rates for VLBW infants have improved dramatically over recent decades due to advances in neonatal care, but they still require careful monitoring and specialized interventions.
Usage
Usage note: Spelled out as V-L-B-W, not pronounced as a word. Distinguish from ELBW (extremely low birth weight, <1000g) and LBW (low birth weight, <2500g).
