Abstract | OBJECTIVES: The purpose of this study was to describe dosage regimens and treatment outcomes in critically ill children receiving ethacrynic acid continuous infusions (CI). METHODS: This retrospective cross-sectional study evaluated patients less than 18 years of age who received ethacrynic acid CI with a duration exceeding 12 hours, from January 1, 2007, through January 31, 2012. The primary objective was to determine the mean/median doses of ethacrynic acid CI. Secondary objectives were to assess surrogate efficacy markers (e.g., urine output [UOP], fluid balance) and the number of patients with electrolyte abnormalities or metabolic alkalosis. Descriptive statistics were used. A series of repeated measures analyses of variance were conducted to assess differences in surrogate efficacy markers and in adverse events that occurred pre-, mid-, and posttherapy. RESULTS: Nine patients were included. The mean ± SD initial and maximum doses (mg/kg/hr) were 0.13 ± 0.07 (median 0.1; range, 0.08-0.3) and 0.17 ± 0.08 (median, 0.16; range 0.09-0.3), respectively. The median UOP (mL/kg/hr) pre-, mid-, and postinfusions (interquartile range [IQR]) were 2.4 (1.8-3.2), 4.2 (3.5-6), and 4 (3.4-5.3), respectively. The median fluid balance (mL; IQR) was 189 (90-526), -258 (-411.7 to 249) and -113.5 (-212.5 to 80.2), respectively. There were statistically significant differences in UOP and fluid balance pre- versus mid- therapy (0.014) and pre- versus posttherapy (p=0.010). No significant differences were noted with magnesium and potassium. Five children (55.6%) developed metabolic alkalosis. CONCLUSIONS: This study provides preliminary evidence for ethacrynic acid CI in children. The median initial dose and maximum dose in this cohort were 0.13 mg/kg/hr and 0.17 mg/kg/hr, respectively. Larger prospective studies are needed to confirm these findings.
