Brief Summary

Hyperkalemia is a common electrolyte disorder, especially among patients with chronic kidney disease, diabetes mellitus, or heart failure. Globally, the reported incidence of hyperkalemia varies from 1.1 to 10 per 100 hospitalizations, depending on the patient cohort and comorbidities. Hyperkalemia is a potentially life-threatening electrolyte disturbance that can be fatal if left untreated. Several studies have established the association between hyperkalemia and all-cause mortality. Because of the deleterious cardiac effects of hyperkalemia, its management is an emergency intervention. However, robust evidence is lacking to guide the emergency management of patients with hyperkalemia. Emergency treatment approaches are largely based on small studies, anecdotal experience, and traditionally accepted practice patterns within institutions. Therefore, a rigorous evaluation of the first-line treatments of hyperkalemia in emergency departments is needed and a large scale randomized clinical trial is warranted before robust recommendations for clinical practice can be made. Our clinical trial will improve the safety of patients with acute hyperkalemia and will help clinicians in their day by day practice to choose the treatment that significantly reduces morbidity and mortality during acute hyperkalemia management. Our results will be delivered in a timely fashion, owing to the high prevalence of hyperkalemia in the emergency department setting and to the commitment of the INI-CRCT network of Excellence, along with ED specialists used to work jointly. the primary objective of our trial is to compare insulin/dextrose intravenous infusion, nebulized salbutamol or combination of nebulized salbutamol and insulin/dextrose intravenous infusion to reduce serum potassium concentration at 60 minutes, as first-line treatment, in emergency departments.

Outcome Measures

Primary Outcomes (1)

  • Mean change in the absolute serum potassium level from baseline to 60 minutes

    The primary outcome of our trial will be mean change in the absolute serum potassium level from baseline to 60 minutes (measured in mmol/l), and will be aggregated using median and interquartile.

    60 minutes

Secondary Outcomes (7)

  • Mean change in the serum potassium level from baseline to 180 minutes and 24 hours

    180 minutes and 24 hours

  • Proportion of patients who had a serum potassium level of 4 mmol/l to less than 4.9 mmol/l at 60, 180 minutes and 24 hours

    60 minutes, 180 minutes and 24 hours

  • Proportion of patients who require re-treatment or dialysis at 60, 180 minutes and 24 hours

    60 minutes, 180 minutes and 24 hours

  • Proportion of patients with adverse effects at 60 and 180 minutes

    60 minutes and 180 minutes

Study Arms (3)

Salbutamol

EXPERIMENTAL

Patients in this experimental group will receive : 10 mg of salbutamol nebulized in 30 minutes (with oxygen 8 liters per minute or with air);

Drug: Salbutamol

Insuline + dextrose

ACTIVE COMPARATOR

Patients in the experimental group will receive : 10 units of regular insulin (rapid-acting, insuline asparte, intravenous injection) as an intravenous bolus with 500 ml of 10% dextrose in water administered over a 30-minute period

Drug: Insulin Aspart

Insuline + Dextrose + Salbutamol

EXPERIMENTAL

Patients in the experimental group will receive either: 1. 10 mg of salbutamol nebulized in 30 minutes (with oxygen 8 liters per minute or with air); OR 2. 10 units of regular insulin (rapid-acting, insuline asparte, intravenous injection) as an intravenous bolus with 500 ml of 10% dextrose in water administered over a 30-minute period plus 10 mg of salbutamol nebulized in 30 minutes (with oxygen 8 liters per minute or with air). The nurse will start by giving the 10 units of insulin and the dextrose, and then, immediately, she will start the nebulization of salbutamol.
