Abstract |
Hypercapnic acidosis is commonly permitted in patients with acute respiratory distress syndrome during the use of protective ventilation strategies. Hypercapnic acidosis is also a common complication of multiple lung diseases and is associated with a poor prognosis, although the mechanisms by which it leads to increased mortality is not known. Previous studies using noninfective models of lung injury show that acute (<6 hrs) hypercapnic acidosis reduced lung damage by an anti-inflammatory effect. We hypothesized that this anti-inflammatory effect would be detrimental in vivo in the presence of untreated bacterial infection and sustained hypercapnia (>48 hrs) and, furthermore, that if bacterial reproduction were controlled by antibiotic therapy, then the anti-inflammatory effects of hypercapnic acidosis would no longer prove detrimental. |
