Overview
Introduction:
One of the risks of diuretic therapy for pulmonary edema is the development of hyponatremia and hypokalemia with pro-arrhythmic potential. The aim of our study was to analyze the incidence of hyponatremia and hypokalemia after the first day of treatment in a real clinical practice.
Methods:
We performed a retrospective analysis of data obtained from medical records. We included all patients with pulmonary edema admitted to the coronary care unit, only patients which died within the first day of treatment were excluded. Absolute dose of administered furosemide, total fluid intake and urine output, saline and pottasium intake were analyzed. Nonparametric paired Wilcoxon test was used to compare natrium and pottasium levels changes.
Results:
37 patients were included into analysis. The median dose of furosemide administered during the first day of treatment was 120 mg (IQR 20–300 mg). Median diuresis was 2 400 ml (IQR 1 425–3 225 ml). The median of difference between diuresis and total fluid intake was 315 ml (IQR 538–1 380 ml). Wilcoxon test confirmed a prevailing statistically significant trend of slight rise in serum sodium within the first day of treatment (serum sodium 138.0 IQR 132.8–139.6 vs 138.1 IQR 134,0–141,7 mmol/l, p = 0.0046). The difference in serum potassium was not statistically significant (serum potassium 4.2 IQR 3.9–4.8 vs 4.2, IQR 3.8–4.8 mmol/l).
Conclusion:
Results did not confirmed the need for a substitution of sodium and potassium losses during the first day of diuretic therapy to prevent hyponatriemia and hypokalemia in patients with pulmonary edema.
