Intrawound vancomycin powder in orthopaedic surgery as surgical site wound infection prophylaxis: A meta-analysis

A meta-analysis research was executed to appraise the consequence of intrawound vancomycin powder (IWVP) in orthopaedic surgery (OPS) as surgical site wound infection (SSWI) prophylaxis. Inclusive literature research till March 2023 was carried out and 2756 interconnected researches were revised. Of the 18 picked researches enclosed 13 214 persons with OPS were in the used researches' starting point, 5798 of them were utilising IWVP, and 7416 were control. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to appraise the consequence of the IWVP in OPS as SSWI prophylaxis by the dichotomous approaches and a fixed or random model. IWVP had significantly lower SSWIs (OR, 0.61; 95% CI, 0.50-0.74, P < .001), deep SSWIs (OR, 0.57; 95% CI, 0.36-0.91, P = .02), and superficial SSWIs (OR, 0.67; 95% CI, 0.46-0.98, P = .04) compared with control in persons with OPS. IWVP had significantly lower SSWIs, deep SSWIs, and superficial SSWIs compared with control in persons with OPS. However, when interacting with its values, caution must be taken and more research is needed to confirm this finding.
