Changes in potassium level and renal function with balanced crystalloid administration in the emergency department

Abstract

A common reason that often makes clinicians hesitate to use balanced crystalloids in the emergency department is the risk of unexpected hyperkalemia in patients with decreased renal function. In this single-center retrospective cohort study, we compared the change in potassium levels before and after administrating a balanced crystalloid, Plasma Solution A, in patients with normal and decreased renal function. Patients who were administered Plasma Solution A and had an electrolyte follow-up potassium test within 24 hours were included. Decreased renal function was defined as an estimated glomerular filtration rate (eGFR) of less than 90 mL/min/1.73 m2. A total of 1134 patients were included, comprising 376 patients with normal renal function (an eGFR >90 mL/min/1.73 m2) and 758 patients with decreased renal function. In patients with decreased renal function, the mean administered Plasma Solution A volume (mL/kg, mean (SD)) was 34.0 (20.1). The mean administration duration (hr, mean (SD)) was 13.9 (4.7). The eGFR (mL/min/1.73 m2, mean (SD)) increased from 52.6 (24.4) to 68.0 (37.6) (p < 0.05), and the potassium level (mmol/L, mean (SD)) decreased from 4.4 (0.6) to 4.1 (0.6) (p < 0.05). Altogether, we found that the potassium level and renal function may not be worsened in patients with decreased renal function within 24 hours after the intravenous administration of approximately 2 L of a balanced crystalloid in the emergency department.
