Abstract

Aim: The purpose of the present study was to compare and analyze differences in antepartal fetal heart rate (FHR) parameters during pregnancy and pregnancy outcomes in normal fetuses and fetuses with nuchal cord (NC). Material and Methods: We surveyed all non-stress test (NST) data acquired using a computerized FHR analysis system at Hanyang University Hospital between 2005 and 2008, and selected 150 cases that had NC. NSTs were performed between 37 and 42 weeks of gestation. Subjects were divided into three groups by the number of NCs: No NC and normal (n = 300), single (n = 124) and multiple NCs (n = 26). Neonatal outcomes were compared, and FHR parameters analyzed using computerized fetal monitoring system. Results: FHR variability, with respect to amplitude (AMP) and mean minute range (MMR), was lower in the multiple NCs group than in the normal group (18.04 ± 0.38 vs 14.54 ± 1.10 bpm, P = 0.0207; 55.69 ± 1.22 vs 44.35 ± 3.41 ms, P = 0.0145, respectively). There were no other statistically significant differences of FHR parameters between the three groups. Baby weight was significantly lower in the multiple NCs group than in the normal group (3317 ± 24 vs 3054 ± 55; P = 0.0008), and there were no other significant differences between the groups. Conclusion: Computerized analysis of FHR would be helpful to assess fetal status, especially in cases of multiple NCs. Multiple NCs may be a subliminal risk factor for the babies even though they present no complications at delivery.
