[Pregnancy monitoring with the Westin gravidogram. II. Symphysis-fundus measurement and the cervix score].

In 830 healthy pregnant women with delivery after the 37th week and parturation of a new-born normal for date (NFD) the Symphysis-Fundus-Measurement (SFM) was established and a standard curve was constructed. The curve is a nearly identic one with that given by the Swedish author Westin. There are significant deviations from the standard curve in patients with large for dates fetuses (LFD) and in those with small for dates fetuses (SFD). For LFD the difference is to make ensure statistically in the 24th and for SFD in the 31th week of pregnancy. Both parameters leave the +/- 1s--Standard-deviation in the 33th week of pregnancy. The +/- 2 s--Standard-deviation is not to be passed over. In twin-pregnancies the +/- 2 s--Standard-deviation is crossed after the 18th week of pregnancy. In obese pregnant women the SFM is to be seen significantly over that of pregnancies with normal body-weight. In conclusion we believe, that by consideration of the +/- 1 s--Standard-deviation and of the values for obese women in the curve of the SFM the distinctive sensitivity for detection of SFD-pregnancies is to be improved. By assessment of the registered dates of 308 Nulligravidae and 260 Multigravidae showing an undisturbed progress of pregnancy and a term--delivery the Westin--Score of the cervix uteri and its underlying single parameters have been ascertained and graphically recorded. The values concerning the Multiparae are a bit higher positioned than those of the Nulliparae. The inclination of both curves are otherwise similar.(ABSTRACT TRUNCATED AT 250 WORDS)
