The combined use of ultrasound examination of hemodynamics in the umbilical artery and urine microalbumin levels can predict adverse pregnancy outcomes in patients with severe preeclampsia

Abstract

The aim of this study was to elucidate the application of ultrasound examination of umbilical artery (UA) hemodynamics with urine microalbumin (UmA) determination in evaluating the outcomes of sPE patients. Altogether 80 sPE patients and 75 healthy pregnant women were recruited. UmA, RI (resistance index) and PI (pulsatility index) were separately measured by ELISA and the ultrasonic Doppler flow detector. The correlation between parameters was analysed using Pearson’s coefficient method. The independent risk factors of sPE were identified using the Logistic regression model. sPE patients had increased UmA, RI and PI (all p < 0.05). UmA level was positively correlated with RI and PI in sPE patients. RI, PI and UmA were independent risk factors of sPE (all p < 0.05). sPE can predict adverse pregnancy outcomes. High UmA levels may increase the risk of poor prognosis. Overall, ultrasound examination of UA hemodynamics with UmA determination can predict the adverse pregnancy outcomes of sPE patients. IMPACT STATEMENT What is already known on this subject? Doppler ultrasound and urine microalbumin (UmA) measurement are important tools in assessing the clinical severity of severe preeclampsia (sPE). What do the results of this study add? This study aims to unravel the application of ultrasound examination of hemodynamics in the umbilical artery (UA) combined with the determination of UmA in evaluating the outcomes of sPE patients. What are the implications of these findings for clinical practice and/or further research? Ultrasound examination of hemodynamics in UA combined with the determination of UmA can predict the adverse pregnancy outcomes of sPE patients.
