    Study Notes

    Surgical Site Infections (SSI)

    • Definition: Bacterial infection that occurs within 30 days after surgery or within 1 year if an implant is left in place.
    • Subtypes: Superficial incisional SSI, Deep incisional SSI, Organ/space SSI.

    Types of Surgical Wounds

    • Clean wound: No intrusion into the gastrointestinal, genitourinary, or respiratory tract, e.g., skin lesion excision.
    • Clean-contaminated wound: Entry into the gastrointestinal, genitourinary, or respiratory tract, but without significant spillage, e.g., elective cholecystectomy.
    • Contaminated wound: Gross spillage from the gastrointestinal, genitourinary, or respiratory tract, or inflammatory response, e.g., bowel perforation.
    • Dirty wound: Traumatic wound with retained devitalized tissue, or a surgical wound with a significant amount of non-viable tissue.

    Antibiotic Use and Infection Prevention

    • Prophylactic antibiotic use is recommended for surgeries with high risk of infection, such as contaminated or dirty wounds.
    • Primary objective of aseptic surgery is to prevent infection.
    • Factors affecting a patient's ability to fight off infection during surgery: Age, nutrition, underlying disease, and medication.
    • Methods for reducing infections during surgery: Aseptic technique, prophylactic antibiotics, and proper wound care.

    Antibiotic Choices for Animals

    • Preferred method for choosing antibiotics for small animals: Culture and sensitivity testing.
    • Preferred antibiotic for anaerobic organism coverage in small animals: Amoxycillin.
    • Preferred method of administering antibiotics for horses: Local administration.
    • Oxytetracycline is used for its broad-spectrum coverage in horses.

    Infection Rates and Risk

    • Infection rate range for contaminated wounds: 3.1-11.8%.
    • Highest risk of infection development: Contaminated wounds.
    • Most common subtype of Surgical Site Infections (SSI): Superficial incisional SSI.
