Methods: Forty rabbits were randomized into five groups to include eight rabbits in each group: group N: normal group, group T: tracheotomized group, group A: ARDS group, group S1: spironolactone group, group S2: surfactant group. Lungs of the rabbits were dissected and examined histopathologically.
Results: HMGB1, CRP, IL-1ß and TNF-α levels were statistically significantly increased in group A. There was a statistically significant decrease in HMGB1, CRP, IL-1ß and TNF-α levels in S1 and S2 groups (p<0.05). While PO2, SpO2, pH and PO2/FIO2 levels were statistically significantly decreased in group A, they were increased in the treatment groups (p<0.05).
Conclusion: As in many studies, our study suggests that surfactant is effective in the treatment of ALI and ARDS, and spironolactone also has a similar effect as surfactant. Spironolactone may be used as a cost effective and efficient agent in ALI and ARDS. Further comprehensive studies are required regarding this subject.
