    Insights

    A single preoperative dose of metronidazole significantly reduced surgical wound infections in a trial of 203 patients. This antibiotic also shortened hospital stays, making it a recommended preventive measure.

    Area of Science:

    • Surgical infection prevention
    • Clinical pharmacology
    • Antibiotic prophylaxis

    Background:

    • Surgical site infections (SSIs) are a significant cause of morbidity and prolonged hospitalization.
    • Effective prophylactic strategies are crucial for improving patient outcomes in surgery.

    Purpose of the Study:

    • To evaluate the efficacy of a single preoperative intravenous dose of metronidazole in preventing surgical wound infections.
    • To assess the impact of metronidazole prophylaxis on hospitalization and convalescence duration.

    Main Methods:

    • A prospective trial involving 203 patients undergoing surgery.
    • Comparison of wound infection rates between a control group and a group receiving metronidazole.
    • Statistical analysis to determine the significance of observed differences (p < 0.001).

    Main Results:

    • Wound infection occurred in 17.5% of the control group versus 3.4% in the metronidazole group.
    • A statistically significant reduction in wound infections was observed with metronidazole use.
    • The metronidazole group experienced significantly shorter average hospitalization and convalescence periods.

    Conclusions:

    • A single preoperative intravenous dose of metronidazole is highly effective in preventing surgical wound infections.
    • Metronidazole prophylaxis is associated with reduced patient recovery times.
    • The study recommends the use of metronidazole for surgical wound infection prevention.
