The Study
Bicarbonate and Other Buffer Therapies in Acute Metabolic Acidosis: A Systematic Review and Meta‐Analysis
This study looked at many different experiments where doctors gave bicarbonate to sick people with too much acid in their blood. It didn’t find strong proof that bicarbonate saves lives, but it does suggest it might help some patients need dialysis less often. We can’t say for sure it causes these benefits because the studies weren’t all perfect.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from
This study looked at whether giving baking soda (sodium bicarbonate) to very sick patients with too much acid in their blood helps them live longer or feel better.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Baking soda doesn't save lives, but it may delay dialysis and reduce dangerous infections in ICU patients, and lower complications in trauma patients — suggesting it helps the body cope, not cure the root problem.
- 2In ICU patients with kidney injury: baking soda reduced dialysis need by 28% and bloodstream infections by 54%.
- 3In heart attack patients: no survival benefit.
- 4In trauma shock: fewer complications (67% less), but didn't help them survive the initial rescue.

Diabetic ketoacidosis, alcoholic ketoacidosis, and severe dehydration cause metabolic acidosis by exceeding the body's natural ability to neutralize excess acid.
In critically ill ICU patients with acute kidney injury and metabolic acidosis, sodium bicarbonate therapy reduces the need for dialysis by 28% but does not increase survival at 28 or 90 days.
Giving sodium bicarbonate to people who have a cardiac arrest outside the hospital does not increase the chance they will survive to reach the hospital or survive for one month, whether or not they had acidosis before treatment.
In ICU patients with acute kidney injury and metabolic acidosis, sodium bicarbonate therapy reduces bloodstream infections by 54%. This reduction is not due to fewer catheters or less dialysis, suggesting sodium bicarbonate has a direct effect on infection pathways.
For patients suffering severe blood loss from trauma, fluids containing bicarbonate lower the combined risk of life-threatening complications like lung failure, blood clotting disorders, and organ failure by 67%, but do not increase the chance of successful resuscitation.
Giving sodium bicarbonate to critically ill patients with metabolic acidosis does not reduce their risk of dying within 28 or 90 days, shorten their stay in the intensive care unit, or lower the rate of organ failure.
