[The antepartum oxytocin fetal assessment challenge test 1,827 case histories. Significance of "prepathological testing". "Results" (author's transl)].

We carried out the Oxytocin Challenge Test (or OCT as American authors call it) by injecting 5 m.U. per minute into pregnant women who are suspect of having high fetal risk from the 34th week of pregnancy onwards. The material that we have examined is from 1,366 cases with 1,827 tests. The perinatal mortality over all was 13.17 per thousand of the cases. We have described three types of response: normal (87.44%), pre-pathological (7.77%) and pathological (6.78%). We have concluded that the test has a good prognostic value and point out the significance of the pre-pathological results, which we think have up till now not been accorded sufficient attention.
