Abstract To explore the clinical value of fetal heart monitoring combined with color Doppler flow imaging for predicting fetal intrauterine growth restriction (IUGR). Methods: A retrospective analysis was performed on the clinical data of 356 pregnant women during the third trimester of pregnancy between March 2017 and December 2020. According to the IUGR comfirmed after delivery, these women were divided into group A (31 cases with IUGR) and group B (325 cases without IUGR). The results of fetal heart monitoring, and the values of umbilical artery blood flow parameters measured by color doppler flow imaging, such as pulsatility index (PI), resistance index (RI), and S/D, of the women were compared between the two groups. The predictive value of fetal heart monitoring combined with color Doppler flow imaging was analyzed by receiver operating characteristic (ROC) curve. Results: The abnormal rate of fetal heart monitoring (83.9%) of the women in group A was significantly higher than that (19.7%) of the women in group B. The values of PI (0.90±0.30), RI (0.75±0.22), and S/D (3.28±0.45) of the women in group A were significantly higher than those (0.77±0.24, 0.65±0.17, and 2.85±0.39) of the women in group B (all P＜0.05). The area under curve, the sensitivity, and the specificity of the fetal heart monitoring combined with the umbilical artery S/D value for predicting IUGR were 0.869, 93.6%, and 80.3%, respectively. Conclusion: Fetal heart rate monitoring combined with color doppler flow imaging has high predictive value for IUGR of the women.
