Abstract

One hundred eight observations of fetal breathing movement(FBM) and the nonstress test(NST) were made. The presenceof FBM was noted in a significantly higher proportion of tests with a reactive NST(77.9%) than a nonreactive NST(69.2%). Conversely, a significantly higher proportion of tests were reactive when FBM was present(90.5%) than when FBM were absent(83.3%). A significant relationship existed between either test and the outcome of pregnancy as judged by the five-minute Apgar score or the incidence of fetal distress in labor. Combining two normal tests did not improve the accuracy in predicting outcome; but the combination of both tests, when abnormal, produced a significant improvement in predicting fetuses likely to have an abnormal outcome. The combination of the normal with the abnormal test had a predictive accuracy similar to a single normal test in predicting a normal five-minute Apgar score. This combination was associated with an incidence of fetal distress in labor intermediate between that seen with either the normal or abnormal test when alone. Neither a single test nor the combination of tests as helpful in identifying the small- for gestational age(SGA) infants. These data indicate that antepartum fetal evaluation may be improved when more than one biophysical variable is used.
