Objective:To evaluate the value of tinidazole (TNZ) injection in the prevention and treatment of obstetrical and gynecological patients with anaerobic infecitons in comparison with metronidazole (MNZ) injection.Method:A dose of 800 mg/200 ml TNZ or 1 000 mg/200 ml MNZ were intravenously infused daily. The gynecological patients received the treatment for 5 days, and the obstetric patients for 3 days. The isolation and culture for anaerobes were performed before and after treatment. At the same time, antibacterial activity in vitro of TNZ against 3 reference strains and 107 anaerobes isolated from patients was examined and compared with the activity of MNZ.Results:The eradication rate or obvious reduction rate of anaerobic bacteria in TNZ group and MNZ group were 91.0% and 44.0%, respectively. The total clinical effective rate of both injections were 94.0% and 82.0%, respectively. The results showed that the clinical efficacy of TNZ against anaerobes was higher than that of MNZ (P<0.01). The both activities in vitro were confirmed also that TNZ was better than MNZ, MICs and MBCs were 0.3950.00 mg/L and 0.78100.00 mg/L, respectively.Conclusion:TNZ is more effective than MNZ in the prevention and treatment of anaerobic bacterial infection in female genital tract.
