The Frequency of Intraventricular Hemorrhage and its Risk Factors in Premature Neonates in a Hospital's NICU.

objectiveIntra-ventricular hemorrhage (IVH) is the leading cause of mortality and disability in premature neonates. The present study aimed to determine the frequency of IVH and its risk factors in the premature newborns admitted to the Neonatal Intensive Care Unit (NICU)at Fatemieh Hospital in Hamadan, Iran, in 2016. METHODS & MATERIALS: This retrospective cross-sectional study was conducted on178 neonates with a gestational age of ≤ 32 weeks admitted to Fatemieh Hospital affiliated to the Hamadan University of Medical Sciences, Hamadan, Iran, in 2016. The study population was selected using the census method. The newborns were subjected to cranial ultrasound on the seventh day of life, and they were assigned into two case and control groups (namely neonates with IVH and those without IVH, respectively). Intra- ventricular hemorrhage was classified into four grades regarding Papile classification. The patients' demographic specifications, including 1- and 5-minute Apgar scores, type of delivery, birth weight, use of mechanical ventilation, prenatal corticosteroid, gestational age, and some complications (e.g., Pneumothorax), were collected using a checklist. The data were analyzed using SPSS software version 16.

resultsAccording to the results, the prevalence of IVH in premature infants admitted to NICU was approximately 20%, and 61.2% of the neonates were male. The participants' mean gestational age was 30.39 weeks. The comparison of delivery type between the case and control groups revealed no significant difference (

conclusionAccording to the findings, the premature newborns admitted to the NICU revealed a relatively high prevalence of IVH. The condition is aggravated in preterm neonates by some factors such as low birth weight, 5-minute Apgar score, gestational age, and the need for mechanical ventilation.
