Medical Dictionary, © 2009 Farlex and Partners
fetal distressObservable 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.
