Abstract
OBJECTIVE: This study aimed to systematically analyze the effectiveness and safety of the local application of vancomycin powder to prevent surgical site infection (SSI) after spinal surgeries and provide guidance for clinical practice. METHODS: Two researchers independently searched PubMed, Web of Science, Elsevier, and China National Knowledge Infrastructure using the MeSH terms "spinal surgery," "vancomycin," "local," "topical," "prophylactic," "surgical site infection," and "SSI" to identify studies published between January 2010 and January 2020 on the local application of vancomycin powder for preventing SSI after spinal surgeries. The outcome assessment indicators were analyzed using RevMan 5.3 software. RESULTS: Three randomized controlled trials, two prospective studies, and 26 retrospective studies were included in the current research. The results of the meta-analysis revealed significant differences between the vancomycin and control groups (non-vancomycin group) concerning the incidence of SSI (risk ratio = 0.39, 95% confidence interval = 0.28-0.55, Z = 5.46), indicating that local application of vancomycin powder can significantly reduce the incidence of SSI. CONCLUSION: Local application of vancomycin powder is an effective and safe method to prevent SSI after spinal surgeries.
