Analysis of 76 ICU patients in Brazil, 44 treated with bronchoalveolar lavage using 3% sodium bicarbonate, showing significantly lower mortality with treatment.
Bronchoalveolar lavage with 10ml of sodium bicarbonate solution directly into the tube (closed circuit), 500μl for each lung segment, followed by aspiration of the solution, performed every 6 hours for 7 days.
risk of death, 75.8% lower, RR 0.24, p < 0.001, treatment 6 of 44 (13.6%), control 18 of 32 (56.2%), NNT 2.3.

Introduction: This study aimed to evaluate the use of sodium bicarbonate solution as an adjunct in the treatment of critically ill patients in an intensive care unit (ICU). Methods: A group of 76 patients were followed up, of which 44 received treatment with a sodium bicarbonate (NaHCO3) solution along with the conventional treatment, and 32 patients used only the conventional treatment. Results: In patients treated, there was an improvement in radiological findings, a decrease in opacity and bilateral consolidations, as well as reduced length of stay in the ICU, and mortality. Conclusion: The use of NaHCO3 solution as an adjunct in the treatment of COVID-19 improved prognosis compared to conventional treatment.
