Abstract

Objectives: To study the acute hemodynamic effects of furosemide in critically ill pediatric patients, the temporal relationship between hemodynamic changes and changes in neuroendocrine axis, and the temporal relationship between hemodynamic changes and urine output. Design: Prospective study. Setting: Pediatric intensive care unit in a tertiary care university center. Patients: Fourteen critically ill pediatric patients who clinically required diuretic therapy. Interventions: Before and after furosemide administration, hemodynamic and neurohormonal measurements were taken. Measurements and Main Results: Hemodynamic and neurohormonal responses to acute diuretic therapy were measured in 14 pediatric patients treated with furosemide (1 mg/kg/dose). Cardiac index deteriorated by 10 mins after drug administration (-9.4 ± 3.9%, p < .05) and was associated with an increase in systemic vascular resistance (17.1 ± 4.8%, p < .05). There was a subsequent increase in cardiac index (20 ± 4.9%, p < .05) at 30 mins, with s decrease in systemic vascular resistance (-11.5 ± 5.2%, p < .05). These hemodynamic changes were associated with marked increases in renin and norepinephrine concentrations and an increase in urinary prostaglandin release. The hemodynamic and neurohormonal effects had their onset before maximum diuresis. Conclusion: Intravenous furosemide administration in acutely ill pediatric patients results in an acute but transient deterioration in cardiac function that appears to parallel the neuroendocrine changes rather than the acute diuresis.
