Abstract
Aim: The association between the growth deficit and the occurrence of adverse outcome was analyzed in a cohort of small-for-gestational age fetuses delivered at term.
Methods: A cohort of consecutive singleton fetuses suspected of being SGA during the late third trimester and delivered beyond 37 weeks was selected. Growth deficit area was calculated as that between the individual 10th centile curve of the customized optimal fetal weight and the individual fetal growth curve.
Results: A total of 55 women were included. Of these, 16 had 28 adverse events: eight cases of umbilical artery pH<7.15, 9 cases of caesarean section for fetal distress and 11 cases of admission to neonatal intensive care unit. Whereas the mean area of growth deficit was 8.8 kg×week units (SD 7.6) for cases with normal outcomes, it was 13.9 (SD 8.04) for cases with adverse outcomes (P=0.03). A growth area deficit >10 units, predicted the occurrence of adverse outcome with a sensitivity and specificity of 62% and 68%, respectively.
Conclusion: In term growth restricted fetuses the degree of growth deficit from the optimal customized growth may be used to identify a subgroup of fetuses at high-risk for adverse outcomes.
