Background
Hypertensive disorders of pregnancy including preeclampsia can be associated with preterm birth and infant mortality and morbidity. It seems that intraventricular hemorrhage (IVH) in preterm neonates born to hypertensive mothers is less common compared to the other ones. In this study, we assessed the relationship between hypertensive disorders of pregnant mothers and the incidence of intraventricular hemorrhage in preterm neonates weighing less than 1500 grams.Methods
In this case-control study, 305 singleton preterm neonates with a birth weight less than 1500 g were entered. The presence of IVH in all preterm neonates was assessed using brain ultrasonography and its correlation to hypertensive disorders of their mothers were evaluated.Results
The prevalence of preeclampsia in mothers with and without pre pregnancy hypertension was 40%, and 15.09% respectively. The prevalence of IVH in preterm neonates was 26.9% (n=82). The incidence of IVH in preterm neonates of mothers with and without preeclampsia was 16.07%, and 29.31%, respectively (p=0.028). The prevalence of IVH in preterm neonates of mothers with hypertension and without hypertension was 12.5% and 29.05%, respectively (p=0.018). Preterm neonates with IVH had a lower mean birth weight, smaller gestational age and lower Apgar scores compared to preterm neonates without IVH with p values of <0.001, <0.001 and <0.01, respectively.Conclusion
Hypertensive disorders of pregnancy increase the risk of preterm delivery, but the incidence of IVH in preterm neonates weighing less than 1500 gr is lower in infants born to mothers with hypertension including preeclampsia compared to those born to non-hypertensive mothers. And also lower gestational age, birth weight, and Apgar scores were important predicting factors for IVH in preterm neonates.Keywords:
