Geburtsüberwachung

  • J. Gnirs

Zusammenfassung

Die Kardiotokographie (CTG) ist heute das Standardverfahren für die Überwachung des Fetus sub partu. Dem Vorteil einer hohen Sensitivität bezüglich der Azidoseerkennung stehen allerdings eine hohe Inter- und Intra-Observer-Variabilität sowie eine nur begrenzte Spezifität gegenüber. Letztere ist vor allem durch die ebenfalls hohe Rate falsch-positiver Befunde erklärbar. Würde man die geburtshilfliche Entscheidung alleine von den Ergebnissen der CTG-Beurteilung abhängig machen, so würden etwa 50% aller wegen drohender fetaler Asphyxie indizierten operativen Entbindungen erfolgen, obwohl der Fetus tatsächlich gar nicht beeinträchtigt war.
