A Citrullinated histone 3 (H3Cit): preoperative and postoperative serum concentrations in each anaesthetic group (represented as median [25–75% interquartile range]). All patient groups show a decrease in H3Cit concentrations postoperatively. B Myeloperoxidase (MPO): preoperative and postoperative serum concentrations in each anaesthetic group (represented as median [25–75% interquartile range]). lidocaine in volatile sevoflurane or propofol intravenous anesthesia effectively reduces the postoperative increase in MPO expression. C Neutrophil elastase (NE): preoperative and postoperative serum concentrations in each anaesthetic group (represented as median [25–75% interquartile range]). lidocaine in volatile sevoflurane or propofol intravenous anesthesia effectively reduces the postoperative increase in NE expression. D matrix metalloproteinase-9 (MMP-9): preoperative and postoperative serum concentrations in each anaesthetic group (represented as median [25–75% interquartile range]). All patient groups show a increase in MMP-9 concentrations postoperatively
