“…Beta blockers may need to be avoided in chronic therapy of neonatal hypertension, particularly in infants with chronic lung disease. In such infants, diuretics may have a beneficial effect not only in controlling BP but also in improving pulmonary function [125]. On the other hand, it should be noted that propranolol is available commercially as a suspension, which makes it convenient to use when beta blockade is not contra-indicated.…”

Hypertension in infancy: diagnosis, management and outcome

2011

View full text Add to dashboard Cite

Advances in the ability to identify, evaluate, and care for infants with hypertension, coupled with advances in the practice of Neonatology, have led to an increased awareness of hypertension in modern neonatal intensive care units. This review will present updated data on blood pressure values in neonates, with a focus on the changes that occur over the first days and weeks of life in both term and preterm infants. Optimal blood pressure measurement techniques as well as the differential diagnosis of hypertension in the neonate and older infants will be discussed. Recommendations for the optimal immediate and long-term evaluation and treatment, including potential treatment parameters, will be presented. We will also review additional information on outcome that has become available over the past decade.

ABSTRACT. Babies with chronic bronchopulmonary dysplasia (BPD) can sometimes develop pallor, systemic and pulmonary edema, oliguria, and hyponatremia not attributable to cardiopulmonary or renal impairment. These signs and symptoms might, however, be explained by inappropriate control of vasopressin secretion. To test this hypothesis, we measured plasma vasopressin and osmolality, serum sodium and potassium concentrations, urine output and osmolality, and free water clearance in 26 normoxic infants with BPD aged 1-4 months. All of these infants required supplemental oxygen (FiOz 0.41 2 0.03, mean -C 1 S E ) to maintain O 2 saturation of >88%, and six infants also required mechanical ventilation. As controls, 1 0 infants of similar age but without B P D were also studied. None of the infants had been discharged from the nursery and was receiving any medications, and all were clinically stable when studied. Compared to control infants, infants with BPD had significantly elevated plasma vasopressin concentrations (control 5.2 2 0.9 pg/ml; BPD 42.4 k 5.1; mean k SE, p < 0.05). Moreover, infants with B P D had hyponatremia and hypotonic plasma, and both urine output and free water clearance were significantly reduced. These data suggest that some infants with chronic BPD have elevated vasopressin levels that are functionally significant. W e speculate that excessive stimulation of vasopressin secretion may explain some of the pulmonary and nonpulmonary signs and symptoms in infants with chronic BPD.

In some infants with BPD, treatment with diuretics has resulted in improvement in lung function and in systemic edema (1, 2). Some of these signs and symptoms are
