[Clinical assessment of utility of computerized system for cardiotocographic analysis in patients with pregnancy-induced hypertension].
OBJECTIVE
Authors decided to study the utility of computerised system for cardiotocographic analysis within the patients with pregnancy induced hypertension (PIH).


METHODS
186 cardiotocograms (average time of registration--1 hour) were thoroughly analysed with special consideration of Dawes-Reedman's criteria. The patients were divided into 2 groups: group I (115 persons) in which cardiotocograms fulfilled Dawes-Reedman's criteria and group II (71 persons) in which cardiotocograms did not fulfil Dawes-Reedman's criteria. Members of each group were in a similar, medium stage of PIH (assessed by gestosis index) according to Klimek, had similar gestational age and gynaecological past. Cardiotocograms were analysed by Computerised System for Perinatal Superintendence AXIS-Sonicaid provided by OXFORD (Great Britain).


RESULTS
Fetal heart rate (FHR) was significantly higher while number of contraction was significantly lower in group II which cardiotocograms did not fulfil Dawes-Reedman's criteria in comparison to group which fulfilled them. In group I which cardiotocograms fulfilled Dawes-Reedman's criteria the number of acceleration up to both 10 and 15 bpm were significantly higher. The number of high variability episodes was significantly higher in group I while number of low variability episodes was significantly higher in group II. Moreover, short term variability was significantly higher in group which cardiotocograms fulfilled Dawes-Reedman's criteria. However, there were no differences between patients in both groups, considering delivery and the state of newborns (assessed by Apgar in 5th minute after birth with similar birth mass and age).


CONCLUSIONS
In conclusion we state that computerised analysis of cardiotocograms plays a crucial role in decision about further treatment in final phase of pregnancy complicated by PIH.
