Evaluation of plasma thiolic groups and reactive oxygen metabolites in critically ill patients

Free thiolic group (SH) and reactive oxygen metabolite (ROM) determination could provide helpful information on the balance between oxidative damage and antioxidant capacity [1]. In previous work we reported the change of the relationship between ROMs and SHs in a group of patients with severe sepsis [2]. In this work we show the values of ROMs and SHs of patients in the ICU divided into three groups according to the gravity of sepsis to investigate a possible relationship between these parameters and the clinical state.
