Ever since the days of Hippocrates the womb has been regarded as a privileged sanctuary in which the fetus was protected against most kinds of harm. Any disturbance promised a premature birth, and doctors did not dare to attempt direct treatment of the unborn. But the more they learned about anemia from Rh incompatibility and the more certain they became of saving nine babies out of ten who are threatened by this disease, the more frustrated they became about the tenth...
...showed the extent to which the baby's Rh-positive cells were being destroyed by antibody from the Rh-negative mother. If the damage was moderate, obstetricians delivered the baby prematurely and gave it transfusions of Rh-negative blood. But if the fluid showed severe damage when the fetus was still too premature for delivery, the obstetrician could only sit back and wait for a malign nature to take its course...
...better-"You couldn't possibly do any harm to the baby, because it couldn't be worse off than it already was." And if it was all right to push a hypodermic needle into the bag of waters, why not keep going and push it into the fetus' abdomen? At National Women's Hospital in Auckland, he did just that. Through the bore of the heavy-gauge needle, he then inserted a thin plastic tube. And through this he injected red cells, Rh-negative like the mother's, to replace the baby...
...Cooke was careful to point out that for the vast majority of women and their babies, the prevailing intake of vitamin D does no harm. But in unpredictable cases, any excess over normal requirements causes unnatural calcium deposition in the fetus: its bones, especially the base of the skull, grow unusually dense, and chalky deposits narrow the aorta. Sometimes the aorta is narrowed around the origin of the renal arteries so that the kidneys are starved of blood and the affected baby suffers from extremely high blood pressure...
...next 60 to 70 days in its mother's pouch, firmly and continuously attached to her breast. During that period, it grows and behaves much as a human embryo in normal gestation. Marquardt researchers are already well acquainted with the opossum, having learned how to detach the tiny fetus from the mother's breast to feed it artificially. Mixing drugs with the food, the researchers should be able to observe firsthand their effects on a growing fetus...
