fetal distress

A nonspecific clinical diagnosis indicating pathology in the fetus. The distress, which may be due to lack of oxygen, is judged by fetal heart rate or biochemical changes in the amniotic fluid or fetal blood.

fetal distress

Observable changes in the fetus during pregnancy or, more often, labour, caused mainly by an insufficient oxygen supply via the placenta. The signs are a sustained rise in the heart rate to above 160/min, slowing of the fetal heart rate after each contraction of the womb, persistent slowness below 120/min, heart irregularity and contraction of the fetal bowel with the passage into the uterine fluid of greenish stools (meconium). These signs do not necessarily indicate lack of oxygen and fetal distress is difficult to evaluate. Fetal blood sampling, through an ENDOSCOPE, may be more useful.

That conclusion, from Australian studies with sheep, supplies a physiologic basis for the link between fetal stress and adult hypertension that has been suggested by several studies of human populations.
Your veterinarian may want to examine the placenta and determine the fetal heart rate, which can be an indicator of fetal stress.
Fetal weight was not compromised by exercise and there were no obvious signs of fetal stress in rats with hypertension that exercised, Gilbert said.
