title: [Characteristics of uterine contraction curve registered by external tocography in imminent premature delivery with tocolytic treatment being given special consideration].
abstract: Characteristics of uterine contraction curve was evaluated from recordings obtained by means of external topography in imminent premature delivery, as well as from comparative analysis of changes of the said characteristics in the course of tocolytic therapy. The study covered 19 pregnant women with imminent premature delivery symptoms and 12 giving birth "at term", in whom respectively 433 and 142 uterine contractions were recorded topographically. After digital processing of the records with the aid of original software, 10 features of curves for changes in the uterine wall tonus, registered in the course of tocolytic therapy by using magnesium sulphate, salbutamol and fenoterol, were subjected to retrospective computer analysis. It has been disclosed that fenoterol caused the earliest and most strikingly expressed changes in the area of analyzed features of the uterine contraction curves, while applying higher doses there was a significant shortening of overall contraction length, and of the time at respective levels of amplitude. Contractions registered in patients with imminent premature pregnancies before the onset of tocolytic treatment were characterized by higher values of features reflecting changes in intrauterine pressure, but by lower values of features associated with the duration of contraction in confrontation with the recordings, accomplished for comparison purposes, of delivery "at term" in the latent phase.
