Recording placental size.

It is routine practice in obstetric hospitals to record the weight of the placenta after each delivery, but the practical usefulness of this measurement has been much debated. Theoretically attractive and more accurate estimations of placental size, such as volume, show no better correlation with birth weight; the usefulness of such relationships is in doubt. Although the variations in size appear interesting, our findings add weight to the suggestions of earlier and recent workers that traditional routine measurements which have virtually no significance should be abandoned until some more meaningful procedure can be found.

The influence of maternal factors on placental weight.

The influence of maternal factors on placental weight has been studied. Their effect may be partially masked as it was not possible to eliminate the effect of fetal factors. For a narrow range of birthweights placental weight correlates increasingly closely with maternal pregnant weight, non-pregnant weight, and weight-for-height; it correlates more closely with all of these than with the baby's birthweight. Maternal obesity has a significant effect on placental weight independent of the possible fetal effect. Maternal height and weight gain in pregnancy share no such effect. Pregnancy weight gain is a poor indicator of feto-placental development.

Further clinical evaluation of the selenomethionine uptake test.

A review of the selenomethionine uptake ratio as a measure of placental function is presented. Attempts at the early identification of the poorly growing fetus were unsuccessful, and the previously published close correlation of results with clinical findings in later pregnancy has not been confirmed. The theoretical basis of the test has been re-examined. Although modification much reduced the incidence of technically unsatisfactory readings, other difficulties prevented the test from being clinically useful. To some extent the aim of the test has been superseded by concurrent developments and advances in care of the premature baby.
