Abstract:
PURPOSE: The objective of this study is to compare the difference of each fetal heart rate (FHR) variables between each categorized group according to birth weight and fetal sex using computerized analysis system of fetal heart rate. METHODS: Non stress test (NST) of four hundred normal pregnant women were grouped based on birth weight to 4 groups, <2,500 g, 2,500~<3000 g, 3,000~<3,500 g and above 3,500 g. Fifty male and 50 female babies entered to each group. So, 100 normal pregnant women entered for the study in each group. For collection and analysis of data and values of each variables, our own FHR interpretation sofware, HYFM-II (Windows version 1.0) was used. RESULT: From the comparison between each group classified by each criteria, there were no specific significant differences in baseline FHR, FHR variability (amplitude & mean minute range), signal loss rate, number of fetal movements, the number of FHR acceleration & the number of FHR deceleration those were obtained by our computerized FHR analysis system. CONCLUSION: We confirm that there were no specific differences in each FHR varibles according to birth weight and fetal sex at least in term normal pregnancy.
