Abstract
Postoperative wound infections represent the most common complication in dermatosurgery. Given the low incidence and heterogeneous data, no standards for perioperative antibiotic prophylaxis (PAP) have been established in clinical practice. To summarize the current evidence on risk factors for postoperative wound infection in dermatosurgery and the new recommendations on PAP. Relevant study data and current recommendations were summarized descriptively. Current evidence suggests that the following factors are associated with an increased risk of wound infection after dermatosurgical procedures: surgery to the lower extremity or the ear, postoperative hemorrhage, defect closure by flap or skin graft, large wound defect, immunosuppression, and male sex. Probably not affecting the risk of infection are diabetes, obesity, age, smoking, use of ablood thinner, multiple surgeries, or wound healing by second intention. Not all risk factors affect the risk of infection equally. They must be weighted differently and only in combination do they increase the risk of wound infection in aclinically relevant way. According to acurrent position paper of the German Society for Dermatosurgery, the indication for PAP should be made individually and only if multiple factors are present. Furthermore, patients with increased risk for bacterial endocarditis or hematogenic endoprosthesis infection should receive PAP prior to septic skin surgery. In dermatologic surgery, PAP should be restricted to patients at high risk for wound infection. Further indications are the prevention of bacterial endocarditis and hematogenic endoprosthesis infection in high-risk individuals prior to septic surgery.
