Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the present study is to compare the adjunct treatment of metabolic or mixed severe acidosis in the critically ill using Sodium Bicarbonate as a buffer to increase the plasma pH vs no buffering therapy.

The study is a randomized multiple center clinical trial with the outcome as a primary endpoint.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

* Design: randomized multiple center clinical trial, open label
* Arms: intravenous 4.2% Sodium Bicarbonate vs no additional treatment
* Inclusion: age of 18 yo or above, critically ill patient with a SOFA score of 4 or above, lactatemia of 2mmol/l or above, with pH of 7.20 or below and PaCO2 of 45mmHg or below and bicarbonatemia of 20mmol/l or below
* Exclusion: single respiratory disorder (PaCO2 \> 50 mmHg, Bicarbonatemia equal or higher than (PaCO2-40)/10 + 24 ; acute diarrhea, ileostomy or biliary drainage ; stage IV kidney failure or chronic dialysis ; tubular acidosis, ketoacidosis, high anion gap acids poisoning (PEG, aspirin, methanol) ; PaCO2 equal to 45mmHg or above and spontaneous breathing, pregnancy, protected patients, moribund patient (life expectancy of 48h or below)
* Randomization: website randomization with stratification on age, presence of sepsis at inclusion, renal failure
* Intervention: experimental arm: intravenous 4.2% Sodium Bicarbonate 125 to 250ml in 30min up to 1000ml/24h. The target is a plasma pH of 7.30 or above.
* An interim statistical analysis is planned when 200 patients will be included
