Interleukin (IL)-8 (A) and tumor necrosis factor-α (TNF-α) (B) serum concentrations in rabbits with Enterobacter aerogenes unilateral pneumonia submitted to the “protective” mechanical ventilation according to the position (i.e., supine position [SP] or prone position [PP]). Results are presented as median ± IQR. A statistically nonsignificant increased of the IL-8 levels within the blood compartment in the animals in PP compared to those kept supine. IQR = interquartile range.
