Estimation of gestational age at birth. Comparison of two methods.

Abstract

Seventy-three low birthweight babies were independently assessed for gestational age using the scoring system of Dubowitz et al. (1970) and 5 neurological reflexes described by Robinson (1966). The results obtained by the 5 reflexes were compared with those obtained by the scoring system and were found to be accurate estimations of gestational age. The 5 reflexes may be used for babies of gestational ages 29 to 37 weeks, but above 37 weeks the scoring system must be used.
