Preliminary observation of the use of sodium bicarbonate solution as an adjunct in the treatment of coronavirus 2019 disease (COVID-19): prognosis improvement in patients requiring intensive care / Observação preliminar do uso de solução de bicarbonato de sódio como coadjuvante no tratamento da doença coronavírus 2019 (COVID-19): melhora do prognóstico na necessidade de terapia intensiva

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.
