[Computer-assisted analysis of cardiotocographic recordings in the course of fetal hemolytic disease].

OBJECTIVES

The aim of this study was to assess the usefulness of computerized cardiotocography in the diagnostics of fetal hemolytic disease.

STUDY

DESIGN

50 invasive diagnostic and therapeutic procedures proceeded by computer assisted CTG recording were analysed. The values of particular parameters of CTG were compared with adequate values obtained in uncomplicated pregnancy. The correlation between both cardiotocographic and hematological parameters was estimated. The common relationship between all analyzed features was examined using multidimensional analysis of variancy.

RESULTS

The most significant correlation was determined in case of short-term variation and hematocrite of fetal blood. The five-feature algorhythm, containing short- and long-term variation, number of accelerations, fetal movements and gestational age, was established for the prognosing of the most probable level of fetal hematocrite.

CONCLUSION

Computerized cardiotocography seems to be the useful diagnostic method which enable to decrease the number of invasive intrauterine procedures in case of fetal hemolytic disease.
