OBJECTIVE: This study was performed to evaluate the application of fetal middle cerebral artery peak systolic velocity (MCA-PSV) for prediction of newborn anemia with umbilical cord blood hemoglobin concentration at birth (UCB-Hb) < 10.0 g/dL among infants born at gestational week (GW) ≥ 36 to unselected women. MATERIALS AND METHODS: We reviewed the medical charts of 699 women giving birth to singleton infants at GW ≥ 36 with available data on MCA-PSV measured at GW ≥ 25 at the discretion of the attending physician. Multiple of the median (MoM) MCA-PSV (MCA-PSV MoM) > 1.5 was defined as a positive MCA-PSV test result. RESULTS: The MCA-PSV test was applied 2309 times (313 and 1996 times during second and third trimesters, respectively) in 699 women. The results were positive in 4.4% (102/2309) of tests and at least once in 9.9% (69/699) of women. Anemic infants were born to one (1.4%) and six (1.0%) of 69 and 630 women with and without at least one positive test result, respectively. MoM determined 4, 3, and 2 weeks before birth showed significant weak negative correlations with UCB-Hb at birth (correlation coefficient: 0.298-0.325). CONCLUSIONS: Among unselected women giving birth at or near term, the MCA-PSV test was unsatisfactory for prediction of newborn anemia in this retrospective observational study.
