Abstract
To assess the impact of intrawound vancomycin on surgical site wound infections in non-spinal neurosurgical operations, we conducted a meta-analysis. A thorough review of the literature up to September 2022 showed that 4286 participants had a non-spinal neurosurgical operation at the start of the investigations; 1975 of them used intrawound vancomycin, while 2311 were control. Using dichotomous or contentious methods and a random or fixed-effect model, odds ratios (OR) and mean difference (MD) with 95% confidence intervals (CIs) were estimated to evaluate the impact of intrawound vancomycin on surgical site wound infections in non-spinal neurosurgical operation. The intrawound vancomycin had significantly lower surgical site wound infections (OR, 0.28; 95% CI, 0.19-0.40; P < .001) with low heterogeneity (I2 = 32%) compared with the control in non-spinal neurosurgical operation. The intrawound vancomycin had significantly lower surgical site wound infections compared with control in non-spinal neurosurgical operation. The low sample size of 2 out of 13 researches in the meta-analysis calls for care when analysing the results.
