Introduction
We determined the impact of gestational diabetes (GDM) and pre-existing diabetes (DM) on birth/placental weight and cord oxygen values with implications for placental efficiency and fetal-placental growth and development.
Methods
A hospital database was used to obtain birth/placental weight, cord PO2 and other information on patients delivering between Jan 1, 1990 and Jun 15, 2011 with GA >34 weeks (N = 69,854). Oxygen saturation was calculated from the cord PO2 and pH data, while fetal O2 extraction was calculated from the oxygen saturation data. The effect of diabetic status on birth/placental weight and cord oxygen values …
