“…If GA is known accurately and NBIs present intrauterine growth restriction, it is better to use an appropriate BW for GA reference or standard. Villar et al 10 define two different altered fetal growth phenotypes, which are analogous to those proposed by the WHO, to define malnutrition in NBIs: stunting and wasting. These phenotypes are defined based on length (stunting) and body mass index (wasting) measurements at birth lower than the P3 of the INTERGROWTH-21 st .…”

“…The new consensus should also include recommendations regarding the most suitable anthropometric curves to use at birth, including the possible use of the recently published international newborn standards [23,24], and outline a uniform way to obtain measurements, especially for infant length. It is also important that an etiology-based separation of infants born SGA be developed, as the risk of complications may vary secondary to the cause of SGA.…”

“…According to a recently published study, the average weight gain for preterm infants at the limit of viability is approximately 15 g per day [12] . Therefore, we did an additional analysis of our data by adding 15 g per day between ultrasound and birth to the EFW for each infant.…”

Introduction: To determine the accuracy of estimated fetal weight (EFW) at the limit of viability in a delivery room setting and its impact on the prediction of neonatal outcome. Material and Methods: In this retrospective, single-center cohort study we included patients with preterm birth between 23⁰/₇ and 26⁰/₇ weeks of gestation. Neonates were divided into 3 groups according to birth weight at delivery (accuracy index 90-110%, <90%, >110%). Neonatal outcome for each group was categorized into survival with and without impairment and death, with a follow-up period of 6 weeks. Results: Eighty-seven newborns were included, with 62.1% accurately estimated. Gestational age at birth, fetal sex, maternal body mass index, and time interval between birth and ultrasound affected the accuracy of EFW. Chances of survival were significantly higher in the underestimated group for birth weight at delivery compared with estimated weight (p < 0.001), with risk of death being significantly lower (p < 0.001). The reverse was true for overestimated infants, for both risk of death and chances of survival. At 6 weeks' follow-up, there were significantly more deceased overestimated infants (p = 0.041). Discussion: Our study shows that inaccuracy of EFW at the limit of viability occurs frequently in a delivery room setting with a potential impact on neonatal outcome.
