Summary
Infants born to mothers with HELLP syndrome face significantly higher risks of neonatal complications like intraventricular hemorrhage and sepsis compared to severe preeclampsia. Early, high-quality management is crucial for improving outcomes in these high-risk pregnancies.
Area of Science:
- Obstetrics and Gynecology
- Neonatology
- Perinatal Medicine
Background:
- Hypertensive disorders in pregnancy, including HELLP syndrome and severe preeclampsia, pose significant risks to both mothers and neonates.
- Preterm delivery is a common complication in pregnancies affected by these hypertensive disorders.
- Neonatal outcomes in pregnancies complicated by HELLP syndrome require careful evaluation and comparison with other hypertensive conditions.
Purpose of the Study:
- To compare neonatal outcomes in preterm infants born to mothers with HELLP syndrome versus severe preeclampsia (PS).
- To evaluate the incidence of specific neonatal morbidities, including intraventricular hemorrhage, sepsis, and respiratory distress syndrome, across different hypertensive conditions.
- To establish the necessity of timely and high-quality medical management for improving maternal and neonatal health in complicated pregnancies.
Main Methods:
- Retrospective chart review of 71 pregnancies complicated by hypertensive disorders (21 HELLP syndrome, 50 PS) and 50 normotensive controls.
- Matching of gestational age and maternal age at delivery among the three groups.
- Statistical analysis using chi-square test and ANOVA to compare neonatal outcomes.
Main Results:
- HELLP syndrome group showed significantly higher rates of intraventricular hemorrhage (IVH), sepsis, and mechanical ventilation (MV) compared to the severe preeclampsia group.
- Compared to normotensive controls, the HELLP syndrome group had increased incidence of neonatal death (ND), respiratory distress syndrome (RDS), IVH, sepsis, intensive care (IC), and MV.
- Severe preeclampsia group also exhibited significantly higher rates of ND, RDS, IVH, sepsis, IC, MV, and low 5-min APGAR scores compared to normotensive controls.
Conclusions:
- Pregnancies complicated by HELLP syndrome are associated with substantially increased neonatal morbidity.
- Neonatal outcomes in severe preeclampsia are also significantly worse than in normotensive pregnancies.
- Early, regular, and high-quality management is essential for improving both maternal and neonatal outcomes in pregnancies with HELLP syndrome and severe preeclampsia.
