    Intra-incisional antibiotics, specifically nafcillin, significantly reduced wound infections in dermatologic surgery. This simple method offers a safe and effective way to prevent post-operative complications.

    Area of Science:

    • Dermatology
    • Surgical Infections
    • Pharmacology

    Background:

    • Wound infections are a common complication following cutaneous surgery.
    • Preventive strategies are crucial to minimize patient morbidity and healthcare costs.

    Purpose of the Study:

    • To evaluate the efficacy of intra-incisional antibiotics in reducing surgical site infections after dermatologic procedures.
    • To assess the safety and convenience of using nafcillin in local anesthesia for cutaneous surgery.

    Main Methods:

    • A prospective, blinded, randomized, placebo-controlled trial was conducted.
    • Patients undergoing Mohs or other dermatologic surgery received local anesthesia with either buffered lidocaine or nafcillin in buffered lidocaine.
    • Wound infections were assessed using a standardized chart at suture removal (5-7 days post-surgery).

    Main Results:

    • A total of 908 surgical wounds were analyzed in 790 patients.
    • The incidence of wound infection was significantly lower in the nafcillin group (0.2%) compared to the placebo group (2.5%) (P = .003).
    • No adverse effects were reported, and observers remained blinded throughout the assessment.

    Conclusions:

    • A single intra-incisional dose of nafcillin administered before dermatologic surgery is highly effective in preventing wound infections.
    • This antibiotic prophylaxis is an inexpensive, safe, and convenient adjunct to standard surgical care.
    • The findings support the routine use of intra-incisional antibiotics in dermatologic surgery to decrease infection rates.
