(1) Direct fetal digitalization led to a reduction in umbilical artery resistance, a decline in the abdominal circumference from 20.3 to 17.8 cm, and resolution of the ascites within 72 h. Despite this dramatic response to therapy, fetal death occurred on day 5 of treatment.
(2) This trend appeared to reverse itself in the low dose animals after 3 hr, whereas in the high dose group, cardiac output continued to decline.

(15) The last stems from trends such as declining birth rate, an increasingly mobile society, diminished importance of the nuclear family, and the diminishing attractiveness of professions involved with providing maintenance care.
