Amniotic fluid volume as a predictor of fetal distress in intrauterine growth retardation
1Division of Maternal-Fetal Medicine, Faculty of Medicine, Chiang Mai University, Thailand.
Objective:
To determine the efficacy of sonographic assessment of amniotic fluid volume (AFV) in predicting intrapartum fetal distress in pregnancies with intrauterine growth retardation (IUGR) compared with the nonstress test (NST).
Method:
A prospective study of 242 pregnancies with IUGR who underwent antepartum assessment of AFV and NST with intrapartum continuous FHR monitoring was conducted and analyzed.
Result:
AFV was a reliable predictor of intrapartum fetal distress with sensitivity, specificity, positive and negative predictive values of 84.0%, 83.41%, 36.84% and 97.84%, respectively. The efficacy of AFV was comparable with that of the NST.
Conclusion:
Sonographic assessment of AFV is an effective predictor of intrapartum fetal distress in pregnancies with IUGR.
