Der Einfluss einer modifizierten Gebärhaltung auf die pulsoxymetrisch gemessene Sauerstoffsättigung des Feten

Die Überwachung der Sauerstoffversorgung des Feten unter der Geburt stellt - auch aus forensischer Sicht - eine der wichtigsten Aufgaben im Bereich der Geburtshilfe dar. In diesem Gebiet ist die Pulsoxymetrie eine der neueren Möglichkeiten der kontinuierlichen Überwachung der Sauerstoffversorgung d...

Table of Contents: The evaluation of the birth position and its effects on maternal and fetal wellbeing has been a topic of perinatal research over the last decades. The aim of our observational study was to determine the effects of a modified and vertical maternal position on fetal oxygen saturation measured by pulse oximetry. METHODS: Fetal oxygen saturation was measured by pulse oximetry in 142 labouring women adopting the supine position, the sitting position, the standing position and the prone position. The statistical analysis addressed the integrated 10 minutes period of SpO2 registrations before versus after adopting the modified position. Furthermore the mean values and the standard deviation (SD) for the total registration periods of different birth position was calculated. RESULTS: While the supine position induced a reduction in oxygen saturation, sitting and prone position were favorable for fetal oxygenation as compared to horizontal position. DISCUSSION: These findings implicate a clinical benefit of the modified birth position.
