Swallowing, urine flow, and amniotic fluid volume responses to prolonged hypoxia in the ovine fetus.

OBJECTIVE Four days of hypoxia produce an extensive fetal polyuria with little change in amniotic fluid volume in the ovine fetus. We hypothesized that fetal swallowing and intramembranous absorption would increase with prolonged hypoxia to offset the polyuria. STUDY DESIGN After a 24-hour normoxic period, nine ovine fetuses were subjected to 4 days of… CONTINUE READING
