title: Correlation between the placental and fetal body weight and size of the rat fetuses affected by intra-uterine administration of neuromuscular blocking agents.
abstract: The data from previous experimental work were analysed and indicated a positive correlation between the placental weight and fetal weight and placental size and fetal size of the rat fetuses affected by intra-uterine administration of neuromuscular blocking agents. Various factors capable of affecting the fetal size and weight were considered. The results tend to support the view that a transient period of reduction in placental blood flow, during the temporary paralysis of affected fetuses, caused their growth retardation and corresponding decrease in the size and weight of their placentae.
