For tidlig vannavgang

For tidlig vannavgang er når fostervannet går uten at det er andre tegn til at fødselen har startet. Seks til tolv prosent av alle fødende er uten rier i inntil en time etter at fostervannet har gått.

Gravid
Flerlingesvangerskap øker risikoen for tidlig vannavgang fordi livmoren blir så stor.

Innhold i artikkelen

Hva er for tidlig vannavgang?

Inne i livmoren "bader" fosteret i fostervann på innsiden av en gjennomsiktig pose (fosterhinnen) som forhindrer lekkasje av fostervann. Fostervannet beskytter barnet. Ved fødselen går det hull på denne posen, og fostervannet renner ut. Tidlig vannavgang er når fostervannet går uten at det er andre tegn til at fødselen har startet. Seks til tolv prosent av alle fødende er uten rier i inntil en time etter at fostervannet har gått.

For tidlig vannavgang innebærer at "vannet går" tre uker eller tidligere før terminen. For tidlig vannavgang kompliserer rundt to prosent av svangerskapene og er årsak til en tredel av alle for tidlige fødsler.
