AIM: Sepsis is a systemic infection reaction and intravascular volume therapy plays a crucial role in it's treatment. Acute respiratory distress syndrome (ARDS) occurs in the lungs, the most affected organ. This study aimed to investigate the different effects of fluid therapy on ARDS caused by sepsis.
METHOD: To form a sepsis model, cecal ligation and puncture (CLP) procedure were performed on 44 adult rats. Divided into six groups; normal, CLP group, those treated with 40 ml/kg 0.9 % NaCl, 3 % NaCl (hypertonic saline), Ringer Lactate and Hydroxyethyl starch. After 24 hours treatments, histopathological examination of the lungs were done, and the plasma levels of CRP, TNF-alpha and IL-6 and paO(2) were measured.
RESULTS: The scores of all histological parameters of the group treated with hypertonic saline were significantly lower than of the other groups (p < 0.001). Likewise, according to the arterial blood gas results, paO(2) was significantly higher (p < 0.01) in the hypertonic saline group compared to the other groups, and paCO(2) was significantly lower (p < 0.01). CRP, TNF-alpha and IL-6 levels of inflammatory markers were also significantly lower in hypertonic saline groups compared to other groups (p < 0.001).
CONCLUSIONS: Our study shows that treatment with hypertonic saline reduces the progression of ARDS in sepsis (Tab. 3, Fig. 4, Ref. 49).
