Intraventricular hemorrhage (IVH) is one of the leading causes of mortality and disability in premature newborns, leading to motor disorder, paralysis, long-term cognitive impairment, mental retardation, and seizure.

Several studies conducted worldwide during the past five years have reported the incidence rate of IVH to be between 20%-40% in preterm infants. The frequency of IVH is 10–20% in preterms born before the 30^th gestational week, and rates of serious IVH increase up to 35–45% in babies born with a birth weight below 750 grams. Post-hemorrhagic ventricular dilatation develops in approximately half of these babies and a permanent ventriculo-peritoneal (VP) shunt is needed in 20–40%.

The incidence of IVH has decreased significantly over the last decade due to the global improvements in neonatal care, which seems to be because of improving practices such as the use of antenatal corticosteroids, practical resuscitation skills, appropriate handling of infants, better infrastructure, and the judicious use of ventilation. However, an increase in preterm delivery resulting from the enhancement of assisted reproductive technology-mediated pregnancy has highly affected the incidence rate of IVH.

IVH is the extension of hemorrhage into the lateral, third, and fourth ventricles and is less prevalent among full-term neonates because they have a more complex germinal matrix. The risk factors for GMH(Germinal Matrix Hemorrhage)-IVH are acute inflammation of the placenta, increased number of leukocytes in the first 72 h after birth, increased white blood cell count, and masculinity. The other risk factors for IVH include prematurity, low birthweight (LBW), long term mechanical ventilation, low 5-minute Apgar score, hypoxia-induced damage, hypothermic ischemia, Pneumothorax, and thrombocytopenia, antenatal maternal hemorrhage, maternal infection/ inflammation, sepsis, hypotension, hypoxia, hypercapnia, seizures, patent ductus arteriosus (PDA), infection, and respiratory distress, genetic factors.

About 15-20% of premature newborns are exposed to IVH, and this is associated with serious complications and mortality in the absence of timely diagnosis and intervention. Since preterm newborns’ brain is sensitive to blood pressure fluctuations, routine care measures seems to be essential among this population

Recently, a series of measures (namely cesarean delivery, delayed cord clamping, minimal handling of infants, avoiding head down position, midline head positioning for 72h, keeping head of the bed up at 15 - 20 degrees, slow infusion of fluids, and antenatal corticosteroids for IVH prevention) have been adopted in different NICUs.

Given the high complication of IVH and its high mortality rate in preterm newborns, and the lack of sufficient research in this regard, the present study aimed to determine the frequency of IVH and its risk factors in the premature neonates admitted to NICU at our Govt. run tertiary care center.
