Infection Prevention in Dermatologic Surgery

Overview / Definition Infection prevention in dermatologic surgery encompasses the measures taken to reduce the risk of infection during and after surgical procedures on the skin. This includes preoperative preparation, intraoperative techniques, and postoperative care aimed at safeguarding patients from potential infectious complications. Epidemiology Infections are among the most common complications following dermatologic surgeries, with reported rates ranging from 1% to 5% depending on the type of procedure and patient factors. Factors influencing infection rates include the surgical site, underlying comorbidities, and adherence to sterile techniques. Common procedures at risk include excisional biopsies, Mohs micrographic surgery, and skin grafting. Patients with diabetes, obesity, or immunosuppression are at higher risk. Pathophysiology / Mechanism Infections occur when bacteria or other pathogens enter the skin through surgical incisions or compromised barriers. The body’s immune response is typically activated to combat these pathogens, but factors like poor wound healing or underlying conditions can impair this response. Normal skin flora includes Staphylococcus epidermidis and other non-pathogenic bacteria. Pathogenic organisms, such as Staphylococcus aureus or Streptococcus species, can lead to surgical site infections (SSIs). Clinical Presentation Infections can present with a variety of symptoms, including: Redness and swelling around the surgical site. Pain that is disproportionate to the surgical procedure. Purulent discharge or foul odor. Fever and systemic symptoms in severe cases. Diagnosis / Workup Diagnosis of surgical site infections typically involves a thorough clinical evaluation. Key steps include: Assessing the patient's history and risk factors. Performing a physical examination to identify signs of infection. Obtaining cultures of wound exudate if indicated. Utilizing imaging studies in cases of suspected deeper infections or abscess form
