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.
