Antibiotic prophylaxis in clean and clean-contaminated plastic surgery: A critical review

Abstract

Antibiotic prophylaxis is frequently used in plastic surgery procedures, despite the generally low rates of infection and few guidelines on the practice. The increasing prevalence of bacterial resistance to antibiotics calls for a reduction in unnecessary antibiotic use. The aim of this review was to create an updated summary of the available data on the effectiveness of antibiotic prophylaxis in reducing the postoperative infection in clean and clean-contaminated plastic surgery. A systematic literature search was performed on the databases Medline, Web of Science, and Scopus, limited to articles published January 2000 onward. Randomized controlled trials (RCTs) were included in the primary review, whereas older RCTs and other studies were sought if 2 or fewer relevant RCTs were identified. Overall, 28 relevant RCTs, 2 nonrandomized trials, and 15 cohort studies were identified. Although the number of studies for each type of surgery is limited, the data suggest that prophylactic systemic antibiotic may be unnecessary in noncontaminated facial plastic surgery, reduction mammaplasty, and breast augmentation. In addition, no benefit is apparent from extending the antibiotic prophylaxis over 24 h in rhinoplasty, aerodigestive tract reconstruction, and breast reconstruction. No studies assessing the necessity of antibiotic prophylaxis in abdominoplasty, lipotransfer, soft tissue tumor surgery, or gender affirmation surgery were identified. In conclusion, limited data are available on the effectiveness of antibiotic prophylaxis in clean and clean-contaminated plastic surgery. More studies on this topic are needed before strong recommendations can be made on the use of antibiotics in this setting.
