Abstract
Aim
The purpose of this study was to evaluate the clinical and surgical variables that may be associated with wound infection and meningitis/ventriculoperitoneal (VP) shunt infection in newborns diagnosed with meningomyelocele (MMC), as well as the efficacy of antibiotic prophylaxis in reducing these complications.
Material and methods
The data of 91 neonates diagnosed with MMC, who underwent surgical intervention between May 2012 and December 2014, were retrospectively evaluated. Multivariant logistic regression analysis was used to determine the possible clinical and neurosurgical variables associated with meningitis/VP shunt infection and surgical wound infection. Spearman’s test was performed for the correlation analysis.
Results
Following MMC closure, of the 91 neonates, 18 (16.4 %) developed meningitis/shunt infection and 12 (11 %) developed surgical wound infection. The operation time was not a significant independent risk factor for the development of meningitis (RR 0.618 [0.199–1.922], p = 0.406). Open neural placodes that were not covered by any pseudomembrane (myeloschisis), external ventricular drainage (EVD) use, and flap transposition were determined as significant relative risk factors for the development of meningitis (RR 8.655 [2.329–32.157], p = 0.001; RR 9.404 [1.183–74.743], p = 0.034; RR 8.125 [2.496–26.448], p = 0.001; and RR 3.150 [1.963–10.308], p = 0.048, respectively). Deep surgical wound infection was not correlated with the operation time or wound surface area. However, there was an intermediate but very significant positive correlation between meningitis and cerebrospinal fluid (CSF) leakage, length of hospitalization, and flap transposition (r = 0.377, 0.420, 0.357, and 0.503, respectively; for all values, p < 0.001).
Conclusions
There was no association between MMC closure and development of infection. Since it carries a high risk for the development of meningitis, the EVD system should be avoided unless necessary. Routine prophylactic antibiotic use did not reduce the infection risk in MMC repair surgery. Thus, antibiotics should not be used if there are no risk factors predisposing to infection.
