The emergence of COVID-19 worldwide in an unprecedented
pandemic. COVID-19 has a signi icant mortality, mostly from
acute lung injury. We reviewed the available literature from
China and Europe in regard to the behavior of SARS-Cov2 and
ability to adhere to the cell wall [1,2]. The evidence based
literature describes three component for the virus to grant
entry to the target cells including Cathepsin B/L (the viral cap
protein needed for initial connectivity to the cell wall), the
angiotensin converting enzyme 2 and a low PH environment
to allow the irst connectivity of the virus to the cell wall [3].
The goal of our Case study was to prevent SARS- SARS-Cov2
from entering target cells by raising the airways PH using
sodium bicarbonate inhalation. The sodium Bicarbonate
inhalation (4.2% concentration) has been used safely in Cystic
ibrosis (CF) patients with inspissated mucoid impaction [3,4]
and in chloride inhalation toxicity by opposing the effect of the
low PH induced by the insulting agent [4,5]. It has not been
administered for COVID -19 patients particularly prior to this
study.
Methods
Four patients required mechanical ventilation due to
COVID-19 pneumonia. All patients have proven positive
COVID-19 RNA collected from the airway’s secretions. Each
one of the patients received inhaled 4.2% sodium bicarbonate
as a salvage therapy. All four patients had severe adult
respiratory distress syndrome (ARDS) and required 100 %
Fraction of inspired oxygen (FIO2). Due to severe hypoxia
despite 100% FIO2, these patients were placed on Positive
end expiratory pressure (PEEP) of 15 to maintain their Oxygen
saturation at 87% at minimum. Also, a standard PEEP of 15
was used throughout the process to keep the alveoli patent to
