Fig. 3From: Effect of sevoflurane and propofol on tourniquet-induced endothelial damage: a pilot randomized controlled trial for knee-ligament surgeryHeparan sulfate and thrombomodulin differences between sevoflurane and propofol groups. Endothelial damage measured by heparan sulfate (a) did not show differences in the serum concentration at any time point. The endothelial cell integrity was similar in both groups as thrombomodulin did not show serum elevation (b)Back to article page
