[History and definition of sepsis--do we need new terminology?].

The history of sepsis demonstrates that despite current knowledge about its pathogenesis the definition of sepsis is more contested than ever. However, a definite terminology is necessary to define the entrance criteria for future clinical studies concerning patients with sepsis or septic shock. For this purpose, in 1991 a consensus conference was held in the US, but its recommendations have not found unequivocal acceptance. These recommendations and their historical background are presented and their consequences discussed.
