Sometimes, the most trusted remedies in medicine crumble under the weight of hard evidence, forcing us to confront uncomfortable truths about what truly saves lives.
Quick Take
- Large-scale study finds sodium bicarbonate infusion fails to reduce mortality in critically ill patients with severe metabolic acidaemia and moderate-to-severe acute kidney injury.
- Medical practice must adapt as assumptions about bicarbonate’s life-saving potential are overturned.
- Clinicians face renewed pressure to reevaluate treatment protocols for acidosis and AKI.
- Patients and families should ask deeper questions about treatment choices during critical illness.
Bicarbonate: The Miracle That Wasn’t
Physicians have long reached for intravenous sodium bicarbonate as a reflexive answer to severe metabolic acidaemia in acute kidney injury (AKI), believing it could tip the scales toward survival. This practice, embedded in critical care protocols, draws on decades of conventional wisdom. If acid builds up and kidneys fail, neutralize it—simple, logical, and persuasive. Yet, a sweeping new study throws a wrench into this narrative, showing no reduction in 90-day all-cause mortality for patients given bicarbonate compared to those who were not. The findings shake the bedrock of intensive care medicine, challenging doctors to reconsider not just a tool, but an entire approach to life-threatening acidosis.

Critical Care Under the Microscope
Acute kidney injury with severe metabolic acidaemia occupies some of the most harrowing real estate in modern hospitals. The standard response has been aggressive: neutralize acidity and stabilize the patient. Sodium bicarbonate, with its familiar fizz and promise, has been the go-to for decades. Yet, the new findings reveal that mortality rates remain stubbornly unchanged despite this intervention. The study’s rigor—spanning a diverse population of critically ill patients—leaves little room for denial. Doctors must ask if their efforts are truly moving the needle or simply maintaining the status quo.
What This Means for Patients and Families
Patients and loved ones, often overwhelmed by medical jargon and the urgency of critical illness, have depended on clinicians to make the best decisions. The new evidence demands that hospitals and families reconsider what “best” really means. When sodium bicarbonate is recommended, it should be backed by clear reasoning, not just old habits.
This is not about denying care, but about ensuring every intervention stands on the solid ground of science. For families, the takeaway is clear: Engage in conversations about treatment choices. Don’t hesitate to ask if a recommended intervention truly improves survival, or if it’s just part of the routine.
