    Area of Science:

    • Pharmacokinetics
    • Thoracic Surgery
    • Infectious Disease

    Background:

    • Antibiotic prophylaxis is crucial in preventing surgical site infections.
    • Cefoperazone is a cephalosporin antibiotic with broad-spectrum activity.
    • Understanding drug distribution in target tissues is essential for optimizing therapeutic efficacy.

    Purpose of the Study:

    • To determine lung tissue concentrations of cefoperazone following a single intravenous dose.
    • To compare lung tissue concentrations with concurrent serum levels.
    • To evaluate the suitability of cefoperazone for perioperative prophylaxis in lung surgery.

    Main Methods:

    • Twenty patients undergoing lung surgery received a single 2g dose of cefoperazone.
    • Lung tissue concentrations were measured at one and two hours post-administration.
    • Serum levels were measured in parallel using high-pressure liquid chromatography (HPLC).

    Main Results:

    • Mean lung tissue concentrations were 45.3-113.3 mg/kg at one hour and 20.5-68.1 mg/kg at two hours.
    • HPLC analysis confirmed rapid and sustained cefoperazone presence in lung tissue.
    • Drug concentrations in lung tissue exceeded those typically required for antibacterial activity.

    Conclusions:

    • Cefoperazone achieves significant and persistent concentrations within lung tissue.
    • The pharmacokinetic profile supports the use of cefoperazone for perioperative prophylaxis in thoracic procedures.
    • Cefoperazone is a viable option for reducing infection risk in lung surgery patients.
