External ventricular drainage (EVD)-related infection (ERI) represents an important condition with potential high morbidity with significant impact on patient outcomes. Prophylactic systemic antibiotics are routinely administered to patients with EVD, but they do not significantly lower the incidence of ERIs. Intraventricular treatment with vancomycin appeared to be safe and effective, but most reports are case-reports/-series and retrospective studies. ⋯ In this first prospective study on this topic, we found that intrathecal Vancomycin administration in EVDs does not reduce the occurrence of ERI compared with intravenous cefazolin prophylaxis, but induces selection of gram-negative bacteria.

External ventricular drainage (EVD) is required to resolve acute hydrocephalus associated with intraventricular hemorrhage (IVH). The correlation of scoring systems of IVH with indications for EVD for acute hydrocephalus related to IVH is currently unknown. ⋯ The LeRoux score is better for identifying patients with IVH who are more likely to have EVD.

Intracranial pressure waveform morphology reflects compliance, which can be decreased by ventriculitis. We investigated whether morphologic analysis of intracranial pressure dynamics predicts the onset of ventriculitis. ⋯ Intracranial pressure waveform morphology analysis can classify ventriculitis without cerebrospinal fluid sampling.

Diagnostic criteria of CNS infection in Patients with External Ventricular Drainage after Traumatic Brain Injury: a pilot study.
Ventriculostomy-related infection (VRI) is a common complication in patients with traumatic brain injury (TBI) treated with an external ventricular drain (EVD). The aim of this study was to investigate incidence and characteristics of patients with VRI, and to explore diagnostic criteria to confidently rule out VRI in patients with TBI. ⋯ In this pilot study of patients after severe, a combination of biomarkers within reference limits ruled out VRI (PPV 0, CI: 0-0.14). Hypoglycorrhachia was a sensitive marker of VRI (NPV 0.97, CI: 0.85-1). Systemic signs and markers of infection did not predict VRI.

Risk factors of ventriculostomy-associated infection (VAI) reported in the literature are variable owing to heterogeneity of external ventricular drainage (EVD) procedures and management. This study aimed to assess the rate of VAI and its risk factors. ⋯ Intraoperative ventriculostomy was independently associated with VAI. Prophylactic EVD exchange at 12.6 days did not lower VAI rate.
