Abstract: AIM: To investigate the dose-related effects of ketamine on cumulative survival in mice models of polymicrobial sepsis induced by cecal ligation and puncture (CLP).METHODS: Mice with CLP were divided randomly into four groups, received ketamine injection intraperitoneally of 0, 3, 6, and 12 mg·100 g-1, respectively, at 1 and 6 h after CLP.The survival rate was observed in each group.RESULTS: No change in mortality was observed after 72 hours among four groups.Ketamine administration was associated with significant improvement of the survival of mice with CLP (P<0.05), especially in 6 mg·100 g-1 group (P<0.05).CONCLUSION: Ketamine administration dose-independently delays lethality from sepsis in mice with CLP.
