The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

The Transfer of Ethyl Glucuronide in the Dually Perfused Ex Vivo Placental Perfusion Model: Implications for Alcohol Screening during PregnancyMatlow, Jeremy 22 November 2012 (has links)
Alcohol consumption during pregnancy can lead to Fetal Alcohol Spectrum Disorder,
and because maternal self-reports are often unreliable, a biomarker of alcohol use during
pregnancy is needed to accurately determine fetal exposure. Ethyl glucuronide (EtG) is a
direct metabolite of ethanol that has been detected in the meconium of infants born to mothers
who consumed alcohol during pregnancy. In the current study, a method was developed and
validated for EtG detection in placental perfusate and tissue using gas chromatography-mass
spectrometry. Subsequently, the ex vivo human placental perfusion model was used to
investigate whether EtG crosses the human placenta. The validated GC-MS method showed
sufficient sensitivity in detecting EtG in placental perfusate and tissue. EtG crossed the
placenta slowly and transfer was incomplete after 3 hours of perfusion. EtG appears to cross
the human placenta and, hence, to represent both maternal and fetal exposure to alcohol.
