importance of maternal ischemia modified albumin, non stress test and doppler ultrasonography in foreseeing perinatal asphyxia

Background: The aim of this study is to evaluate the importance of ischemia changed albumin, in foreseeing fetal asphyxia and comparing it between normal and preeclamptic pregnant.Method: We planned our study as a prospective case-controlled study between May 2011 and June 2013. We recruited 104 pregnant women complicated by preeclampsia and 110 healthy pregnant women in the study. Doppler ultrasonography, non-stress test and fetal biometric measurements were performed. Venous blood samples taken to measure ischemia modified albumin (IMA). The presence of fetal hypoxia/acidosis was analyzed by conducting post-natal cord blood gas examination and 1.-5. minutes APGAR scoring.Results: Women with preeclampsia had higher IMA compared to controls. The correlations between umbilical artery doppler systolic/diastolic (S/D) ratio, brain sparing effect, non stress test and IMA analyzed. We have found IMA statistically high when S/D ratio is above 2 standard deviations (preeclampsia; 11.83±1.33 vs 19.62±1.56 p<0.001, control; 10.28±1.57 vs 18.09±2.13 p<0.001) or brain sparing effect started (preeclampsia; 25.59±2.48 vs 9.16±1.99 p<0.001, control; 16.37±1.97 vs 6.72± 1.53 p<0.001) or abnormal NST findings occurred (preeclampsia; 10.69±1.92 vs 20.72±1.15 p<0.001, control; 7,42±1,94 vs 9,72±2,19 p<0.001).Conclusions: Maternal IMA levels are found high in preeclamptic pregnant women and it can be used as a biomarker for determining fetal wellbeing.
