Abstract
Background: The intrawound application of vancomycin powder in addition to intravenous administration of antibiotics has been reported to be an easy and cost-efficient technique for reducing the deep infection, which is a serious complication of spinal surgeries. The aim of the present meta-analysis was to derive a preliminary estimation on the clinical performance of this technique.
Hypothesis: The intrawound application of vancomycin powder in addition to intravenous administration of antibiotics may significantly reduce the risk of deep infection after spinal surgeries.
Materials and methods: Studies were identified from PubMed and EMBASE searches. After comprehensive review, data were extracted from eligible studies. A meta-analysis was performed to generate pooled odds ratio (OR) of this technique.
Results: Eight studies (4592 patients) were included. The pooled OR (95% CI) was 0.22 (0.07-0.63). I(2) value was 65.2% (P=0.005). The pooled ORs were stable in sensitivity analyses. No analysis of subgroup, meta-regression or publication bias was performed because of inadequate included studies.
Discussion: The intrawound application of vancomycin powder in addition to intravenous administration of antibiotics may significantly reduce the risk of deep infection after spinal surgeries. Further studies with large sample size and high quality are needed to provide more evidences.
Level of evidence: II.
Keywords: Deep infection; Intrawound; Spine; Vancomycin.
