predictive accuracy of nonstress test in high risk pregnancies
نویسندگان
چکیده
there are now several tests available that can assess fetal status. a series of 164 cases of high risk pregnancies were studied in order to assess predictive value of a nonstress test. the majority (36%) of patients complained about postdate pregnancy. a nonreactive test was identified in 24 of the patients (14.6%). fetal distress, low apgar score in 1 and 10 minutes after birth and mean of apgar score in 5 minutes, cesarean section due to fetal distress, congenital anomalies, need of neonatal care, iugr, abnormal presentation and perinatal death were much more common in the group of pregnancies with a nonreactive nst than in the group with reactive test. the difference was statistically significant. a reactive test was found to be a good predictor of the healthy fetus. negative predictive value and specifity of the test were found 80% and 91.9%, respectively. the nonreactive test could identify a population at risk but it was not helpful as a stand alone modality in decision making, because of the low sensitivity and positive predictive value rates (33.3% and 58%).
