Neonatal Hypertension

Renal blood flow in high and low positions of aortal catheter in rabbits

“…The thrombosis caused by the aortal catheter appears most commonly in the aorta or in the iliac arteries [4]. Thrombosis of the renal arteries is not uncommon, either [1]. The exact mechanism of this complication is unclear.…”

“…Further, the most severe complication is thrombosis of the renal arteries [2]. Several authors have suggested that thrombus formation is more common if the tip of the catheter is above rather than below the aortal origins of the renal arteries [1]. Some reports,however, have shown that the frequency of complications is greater when the catheter is in low position [6].…”

Hypertension in Neonates: Need for Future Research

“…When compared to paediatric and adult population where there are cut-off values of blood pressure for labelling hypertension, there are no such cut-off value in the neonatal age group. There are also no management protocol defining first line and second line anti-hypertensive to be used in these hypertensive neonates, when compared to paediatric and adult population [2]. In this review article we will cover in brief about various aspects of neonatal HT and details over this issue can be read from other published reviews of the author [1,3,4].…”

Patterns of Blood Pressure in Infants who Survived from a Neonatal Intensive Care Unit

“…The recent advances in neonatal intensive care have made it possible for the evaluation, diagnosis and care of newborns with hypertension (2). Many investigators have shown that renovascular or renal parenchymal diseases are the most common causes of hypertension in the early years of infancy (3,4). It is estimated that hypertension occurs in 0.2-3% of newborns admitted to the NICU though standardization of blood pressure measurement in this age group is not completely settled (2,4).…”
