[Inversion of the uterus during cord traction]

Two cases of the uterine inversion during cord traction is described. Both women were primiparae, aged 26 and 19, respectively. Once there was a shorter umbilical cord and once the adherent placenta. In both cases the manual reposition of the uterus proved successful, but the patients were threatened by the shock, one of them even developed the heart arrest. The authors draw attention to the fact that the cord traction method in the third stage of labour could be exceptionally dangerous, in spite of its other advantages.
