Fetal Hemodynamic Response to Maternal Oxygenation in Normal and Complicated Pregnancies

Abstract

Maternal oxygenation (MO) is widely applied in obstetrics. Scholars have conducted numerous studies on maternal hyperoxygenation and have reported many theoretical and applied achievements and a number of different points of view. The main purpose of this article is to discuss the effect of maternal oxygenation on fetal circulation during normal and complicated pregnancies and to ascertain its potential side effects and research gaps in this field. In complicated pregnancies, the fetus may benefit from oxygen therapy. However, large randomized controlled trials and longitudinal studies are necessary to support the widespread application of maternal oxygenation in this context.

Zusammenfassung

Die maternale Oxygenierung (MO) findet in der Geburtshilfe breite Anwendung. Wissenschaftler haben zahlreiche Studien zur maternalen Hyperoxygenierung durchgeführt sowie über viele Errungenschaften in Theorie und Praxis und über einige unterschiedliche Auffassungen berichtet. Das Hauptziel dieses Artikels besteht darin, den Einfluss der maternalen Oxygenierung auf den fetalen Kreislauf bei normalen und komplizierten Schwangerschaften zu diskutieren und potenzielle Nebenwirkungen sowie Forschungslücken auf diesem Gebiet zu ermitteln. Bei komplizierten Schwangerschaften kann der Fötus von einer Sauerstofftherapie profitieren. Allerdings sind große randomisierte kontrollierte Studien und Langzeitstudien notwendig, um den allgemein verbreiteten Einsatz der maternalen Oxygenierung in diesem Zusammenhang zu befürworten.
