Plasma-Lyte 148 versus saline for treating moderate to severe diabetic ketoacidosis

Balanced Multi-electrolyte Solution Versus 0.9% Sodium Chloride as Fluid Therapy for Patients Presenting With Moderate to Severe Diabetic Ketoacidosis

Phase 3 Interventional The George Institute · NCT05752279

This trial tests whether giving Plasma-Lyte 148 instead of standard saline helps adults with moderate to severe diabetic ketoacidosis be alive and out of the hospital for more days by day 28.

What this trial studies

This is a blinded, cluster cross-over, randomized controlled Phase 3 trial comparing Plasma-Lyte 148 to 0.9% sodium chloride for initial fluid therapy in adults presenting to the emergency department with moderate to severe diabetic ketoacidosis who require admission to a critical care area. Patients meeting biochemical criteria for DKA (blood glucose >14 mmol/L, pH <7.25, bicarbonate <15 mmol/L, elevated anion gap, positive ketones) are enrolled and receive whichever study fluid is assigned for their cluster period. The primary outcome is days alive and out of hospital to day 28, with secondary outcomes including resolution of acidosis and usual safety measures. The trial is conducted at several New South Wales hospitals and is designed to provide definitive phase 3 evidence on fluid choice in DKA.

Who should consider this trial

Good fit: Adults in the ED with moderate to severe DKA who need admission to an ICU or high-dependency unit and meet biochemical criteria (glucose >14 mmol/L, pH <7.25, bicarbonate <15 mmol/L, elevated anion gap, positive ketones) are ideal candidates.

Not a fit: People under 18, those with hyperosmolar hyperglycaemic non-ketotic syndrome, major sodium abnormalities, a contraindication to either fluid, or who have already received >2000 mL of non-study fluid before enrolment are unlikely to benefit from joining this trial.

Why it matters

Potential benefit: If successful, using Plasma-Lyte 148 could shorten recovery from acidosis and increase the number of days patients are alive and out of the hospital within 28 days.

How similar studies have performed: Smaller studies in DKA have suggested Plasma-Lyte may lead to faster acidosis resolution with similar glucose control, but definitive large randomized phase 3 evidence has been limited.
