[Possibilities to influence the duration of labor through decompression treatment during the third trimester]

Comparative examinations of labour duration in primipara and multipara of the age groups: before 20, between 20 and 25, 25 and 30, and over 30 (so called "old primipara") were performed. Equal numbers of women with and without abdominal decompression treatment during the III. trimenon were analysed, altogether 1312 patients. In the groups before 20 and between 20 and 25 years of age only an insignificant decrease in duration in treated cases against the control group was found objectively, despite the almost subjectively reported easing and shortening of labour.--On the other hand in 30 year old patients a clear and in over 30 year old women (so called "old primipara") a highly significant decrease was recognizable, which demonstrates the value of prenatal preparations by abdominal decompression treatment in these age group.
