[Synchronous cardiotocographic registration of fetal body and respiratory movements in placenta insufficiency].
The extent of fetal movements and their reflections in the cardiogramme were studied in 44 normotrophic and 39 hypotrophic fetuses under standardized conditions using real time ultrasound examination of fetal body and respiratory movements and synchronous registration of fetal cardiogrammes from a uterus without labour. Altogether, hypotrophic fetuses exhibited fewer movements than normotrophic fetuses did. Numbers and parameters of accelerations in fetal heart rate occurring in connection with fetal body movements were less marked, too. The acceleration amplitude was particularly significant. Further comparisons between fetuses born with pHa greater than or equal to 7.20 and less than 7.20 or 1- and 5-minute Apgar scores greater than or equal to 8 points and less than or equal to 7 points revealed statistically significant (alpha = 0.05) differences in the frequency of movements and movement-associated accelerations in fetal heart rate only in fetuses with a body weight less than or equal to the 5th weight percentile according to Kyank (n = 21). Fetuses with a body weight between the 6th and the 10th weight percentiles (n = 18) and normotrophic fetuses did not, or did only faintly, reveal these differences. A ratio calculated from the acceleration amplitudes and the durations of associated body movements differed significantly between impaired and unimpaired born fetuses during defined intervals of the duration of fetal body movements.
