ABSTRACT
Infections associated with neurosurgical procedures are serious complications that contribute to the morbidity and mortality of neurocritical patients, as well as to the prolongation of the stay in the ICU and the hospital. The diagnosis is complex since there is no gold standard, so it is based on clinical suspicion, CSF physical-chemical examination, and microbial isolation. Treatment should be initiated early, guided by local epidemiology. The duration will depend on the causative microorganism, its sensitivity and the availability of antibiotic treatments that are effective at the site of infection. The implementation of preventive measures with proven efficacy minimizes the risk of infection. This SADI-SATI intersociety update reviews relevant data recently published on this area at the national at international level regarding epidemiology, diagnostic methodologies, therapeutic approaches, and prevention guidelines.
Las infecciones asociadas a procedimientos neuroquirúrgicos son complicaciones graves que contribuyen a la morbimortalidad de los pacientes neurocríticos, así como también a la prolongación de la estancia en la UTI y/o en el hospital. El diagnóstico es complejo ya que no se dispone de gold standard y se apoya en la sospecha clínica, las alteraciones físico-químicas del líquido cefalorraquídeo y el aislamiento microbiano. El tratamiento debe ser precoz y guiado por la epidemiología local. La duración dependerá del microorganismo causal, su sensibilidad y la disponibilidad de tratamientos antibióticos efectivos en el sitio de la infección. La implementación de medidas de prevención con evidencia demostrada minimiza el riesgo de infección. Esta puesta al día intersociedades SADI-SATI presenta datos epidemiológicos (internacionales y locales), métodos diagnósticos, tratamiento, y pautas de prevención, considerando las publicaciones más relevantes de los últimos años sobre el tema.

UNLABELLED: A common (5%) complication of cerebrospinal fluid (CSF) shunt systems is infection. CSF cytochemical findings have been used to choose the initial empirical antimicrobial treatment. The objective was to evaluate the results of cytochemical and microbiological analyses of CSF samples obtained from children with pyogenic ventriculitis associated to ventriculoperitoneal shunt systems. This was a retrospective, descriptive and analytical study. Thirty-two cases of pyogenic ventriculitis were included; Gram-positive bacteria were predominant in 26 cases (81.25%); the rest corresponded to Gram-negative bacteria. There were no statistically significant differences for the studied outcome variables (CSF cellularity, glucose and protein levels). CONCLUSION: Gram-positive bacteria were widely predominant as a cause of pyogenic ventriculitis associated to the surgical procedure. CSF characteristics show a high heterogeneity and were not associated to the type of microorganism in this studied sample.

BACKGROUND: Infection is a major complication in patients undergoing external ventricular drainage (EVD). Our study aimed to evaluate the incidence of infection in a series with the monoblock EVD system. MATERIAL AND METHODS: 46 patients treated with EVD at our emergency department were analyzed prospectively to research the incidence of infections with a new EVD system. RESULTS: The average rate of infection was 8.7%. When we stratified the patients according to the exclusive use of EVD without craniotomies, we identified a reduction in the overall incidence of ventriculitis from 8.7% to 2.3%. Age, etiology, and the presence of ventricular bleeding were not statistically significant risk factors. CONCLUSIONS: Despite the small sample examined in this study, we believe that the monoblock system is a simple, inexpensive device that reduces accidental disconnection of the system.
