Abstract
Childhood hypertension is defined as average SBP or DBP that is greater than or equal to the 95th percentile for sex, age, and height on at least three separate occasions. Neonatal Hypertension is defined as systolic BP more than 95% for infants of similar size, gestational age and postnatal age, the incidence of neonatal hypertension ranges from 0.2% to 3% and is more common in the term or preterm neonates who are admitted in the neonatal intensive care units or undergo umbilical catheterization. Renal vascular and renal parenchymal diseases are the two common etiologies of neonatal hypertension Thromboembolic occlusion of renal artery, following umbilical artery catheterization, is the most common cause of neonatal hypertension. Symptoms of neonatal hypertension are often non-specific and are frequently masked by concurrent medical illness including cardiopulmonary symptoms, neurologic disorders, apnea, tachypnea, lethargy, irritability and feeding difficulties.
