Conclusion
Our research showed that six identified factors associated with fetal
distress and four independent predictors were selected for admission to
NICU of patients with FGR. The application of LMWH during pregnancy
could reduce the incidence of fetal distress. The delivery method of
cesarean section increased the above risks. Two nomograms were the first
to developed and verified which had good discrimination and good
calibration respectively. They are valuable for clinical prediction and
practicality. Establishing effective predictive models based on
independent predictors could help early diagnosis and evaluation of
fetal distress and admission to NICU in patients with FGR.
