Plasma concentrations of catecholamines and cytokines at the end of the experiment. LPS = lipopolysaccharide, TEA = thoracic epidural anesthesia. IL-1β = interleukin-1β, TNF-α = tumor necrosis factor-α. Data are median [quartiles], # p < 0.05 vs. LPS - TEA – and LPS + TEA +; * p < 0.05 vs. LPS - TEA -.
