I totally agree with a
previous email that the people who make the rules ought to have to demonstrate
what the procedure is actually proving or helping. But here's a link to a study
more generally that also deals with weighing.

Midwifery. 1991 Mar;7(1):31-9. Related Articles, Links A contemporary view of the human placenta. Fox H. Our current knowledge of the human placenta is briefly reviewed. Particular stress is placed upon the considerable functional reserve capacity of the placenta, the unimportance of most visible abnormalities of the placenta, the lack of any evidence that the placenta ages during gestation and the lack of significance of placental weight. The effects on the placenta of infection and of maternal cigarette smoking are considered and the concept of placental insufficiency critically discussed. It is concluded that most cases of 'placental insufficiency' are, in reality, examples of maternal vascular insufficiency resulting from inadequate placentation during the early stages of pregnancy. |
