Dubowitz examination
Pronunciation: DUE-bow-itz
Comprehensive neurological and physical assessment tool used to estimate gestational age in newborns, particularly when maternal dates are uncertain.
Full Definition
The Dubowitz examination is a standardized assessment combining neurological criteria and external physical characteristics to estimate gestational age in newborns. Developed by Lilly and Victor Dubowitz, this examination evaluates neurological signs such as posture, square window sign, arm recoil, and popliteal angle, along with physical criteria including skin texture, plantar surface creases, breast development, and genital maturation. The assessment is most accurate when performed within the first 48 hours of life and can estimate gestational age within 1-2 weeks. While the Ballard examination (a modification of Dubowitz) is more commonly used today, the original Dubowitz examination remains important for understanding neonatal assessment principles.
Usage
Usage note: Often replaced by the Ballard examination in current practice but remains historically and educationally important.
