OBJECTIVE: The purpose of this study was to determine the effect of birth weight discordance (BWD) and @entity3465 on twin neonatal outcome by measuring Apgar scores and blood @entity413 concentrations at birth. METHODS: This was a retrospective cross-sectional study. All twins born at NY Methodist Hospital between January 1998 and December 2001 were eligible. Excluded were @entity5617 , maternal @entity262 , @entity600 , neonates with birth weight < 500 g and multiple gestation greater than 2. BWD was defined as intrapair difference in birth weight expressed as percentage of the larger twin greater than 20% and @entity3465 as gestation of less than 37 weeks. @entity4053 was defined as blood @entity413 concentration < 40 mg/dl. RESULTS: There were 75 (48%) preterm and 80 (52%) term twin pairs. Nineteen (12%) of the preterm and 15 (9.6%) of the term showed BWD. Mean Apgar scores at 1 and 5 minutes were higher for the term twins as expected. Neither @entity3465 nor @entity4053 was present predominantly in BWD twins. Twelve of the preterm and six of the term BWD twins showed evidence of @entity4053 . CONCLUSION: @entity4053 in the early hours of postnatal life is relatively common in preterm BWD twins. Blood @entity413 measurement using reagent strips is an efficient way of monitoring blood @entity413 concentrations in these @entity1 .
