A simplified method for diagnosis of gestational age in the newborn infant.
concept that conversion of T4 to T~ depends upon a 5'monodeiodinase enzyme system that is immature at birth? The 3,3'T2 is thought to be derived at least in part from the peripheral conversion of T~Expand

Effects on fetal heart rate and fetal pO2 of oxygen administration to the mother.
Abstract In 21 full-term pregnant women during labor, the administration of oxygen to the mother caused a rise in fetal muscular pO 2 . Oxygen administration had no effect on normal fetal heart rate.Expand

A quantitative study of the action of synthetic oxytocin on the pregnant human uterus.
The effect on uterine contractility of synthetic oxytocin given by continuous infusion at the rates of 1, 2, 4, 8, 16 and 32 mU/mm. has been quantitatively studied on pregnant women. The record ofExpand

Relationship between blood pH and heart rate in the human fetus during labor.
Abstract In 9 labors at term pregnancy, fetal heart rate (FHR) and amniotic pressure were recorded electronically from the onset of labor until delivery. The actual pH was periodically determined inExpand

Aortocaval compression by the uterus in late pregnancy. 3. Unreliability of the sphygmomanometric method in estimating uterine artery pressure.
Abstract In late pregnancy sphygmomanometry of the brachial artery does not give a reliable estimate of the simultaneous pressure in the arteries which are distal to compression exerted on the aortaExpand
