Frequency of Intraventricular Haemorrhage (IVH) in Early Preterm Neonates Born at DHQ Teaching Hospital Gujranwala

Abstract

Objective: The reported frequency of intraventricular hemorrhage in preterm neonates varied greatly. We determined the frequency of IVH in premature neonates in the pediatric unit of DHQ Hospital Gujranwala. Materials & Methods: This cross-sectional study involved 282 very low birth weight neonates (birth weight <1500 gm.) delivered very preterm (gestational age <32 weeks). These neonates were assessed for intraventricular hemorrhage which was diagnosed on cranial ultrasound performed on 3rd day of life. The frequency of IVH was compared across various attributing factors i.e., gestational age at delivery, gender, birth weight, mode of delivery, and maternal antenatal steroids. Results: The mean gestational age at delivery was 27.5±2.3 weeks while the mean birth weight was 1120.5±190.2 grams. 172 (61.0%) neonates were delivered vaginally while C-section was performed in 110 (39.0%) cases. 263 (93.3%) mothers received antenatal steroids. Intraventricular hemorrhage was diagnosed in 64 (22.7%) early preterm neonates. The frequency of IVH increased significantly with increasing prematurity; 24-27 weeks vs. 28-31 weeks (28.9% vs. 17.0%; p-value=0.017), decreasing birth weight; <1 kg vs. ?1kg (31.8% vs. 18.6%; p-value=0.014) and lack of antenatal steroids (52.6% vs. 20.5%; p-value=0.001). Conclusion: The intraventricular hemorrhage was observed in 22.7% of early preterm neonates which advocates routine screening of preterm neonates for IVH so that timely identification and anticipated management may improve the outcome of such neonates. We also identified increasing prematurity, decreasing birth weight, and lack of antenatal steroids as potential attributing factors that can be used for risk stratification and management planning of such cases.
