Placental transfer of 10 per cent ethanol infused at a rate of 15 ml.
Abstract
Placental transfer of 10 per cent ethanol infused at a rate of 15 ml. per kilogram per 2 hours (0.125 ml. per kilogram per minute) was investigated in pregnant sheep. Fifty-four paired uterine arterial and umbilical vein blood alcohol levels from 15 sheep were analyzed. The lag in umbilical vein alcohol levels below maternal arterial is 15 to 30 mg. per cent. Umbilical artery versus umbilical vein and uterine vein versus maternal artery levels are also discussed.
