    Cefazolin antibiotic prophylaxis significantly reduced infection rates in vascular surgery patients compared to placebo. Povidone-iodine skin preparation was also more effective than hexachlorophene-ethanol.

    Area of Science:

    • Surgical Infection Prevention
    • Vascular Surgery
    • Pharmacology

    Background:

    • Antibiotic prophylaxis is common in peripheral vascular surgery, but evidence from controlled studies is limited.
    • Infection prevention strategies require rigorous evaluation to optimize patient outcomes.

    Purpose of the Study:

    • To evaluate the efficacy of cefazolin versus placebo in preventing surgical site infections.
    • To compare the effectiveness of different skin antisepsis methods in vascular surgery.

    Main Methods:

    • A randomized, prospective, double-blind study involving 565 arterial reconstructive operations.
    • Comparison of cefazolin prophylaxis against placebo in patients undergoing abdominal aorta and lower extremity vascular surgery.
    • Retrospective analysis of skin antisepsis methods: hexachlorophene-ethanol vs. povidone-iodine.

    Main Results:

    • Significantly lower infection rates in the cefazolin group (0.9%) compared to placebo (6.8%) (p < .001).
    • Four vascular graft infections occurred exclusively in the placebo group.
    • Povidone-iodine skin preparation resulted in significantly lower infection rates than hexachlorophene-ethanol (p < .01).

    Conclusions:

    • Perioperative cefazolin administration and povidone-iodine skin antisepsis are recommended for vascular reconstructive surgery.
    • These interventions significantly reduce the risk of surgical site infections in the abdominal aorta and lower extremity vasculature.
    • Cefazolin demonstrated a favorable safety profile with no observed adverse effects or resistant strain emergence.
