BACKGROUND: Intravenous (IV) hydralazine is frequently used for the treatment of elevated blood pressure (BP) in hospitalized children. Its safety and efficacy have not been examined.
METHODS: This is a retrospective chart review of IV hydralazine use in hospitalized children (birth to 17 years) over a 3-year period. Demographic data and data on adverse effects (AE), BP, and heart rate (HR) prior to and after each first dose were collected.
RESULTS: The patient cohort comprised 110 children admitted to the hospital during the study period, of whom 77 received the recommended dose. Mean age of the children was 8.5 ± 5.4 years; 33 % were male, and 32.5 % were white. Pre-dose systolic and diastolic BP indexes were 1.3 and 1.2, respectively. The median reduction in systolic and diastolic BP was 8.5 and 11.5 %, respectively. Sixteen (21 %) children achieved a 25 % reduction in systolic or diastolic BP, and BP increased in 30 % of patients; 10 % of children had a BP of <95th percentile for age, sex, and height after one dose. Seven (9 %) children had a documented AE. HR increased by a median of 3.5 %. In the multivariable models examining percentage change in systolic and diastolic BP, male gender was significantly associated with a change in systolic BP.
CONCLUSIONS: In hospitalized children, IV hydralazine was well tolerated, BP response was variable, and 21 % of the patients achieved a ≥25 % reduction of systolic or diastolic BP. Further studies are needed to compare the safety and efficacy of IV hydralazine to other short-acting antihypertensive agents.
