The placement of external ventricular drain (EVD) is a common neurosurgical procedure to drain cerebrospinal fluid (CSF) in many acute neurosurgical conditions that disrupt the normal CSF absorption pathway. Infection is the primary complication with infection rates ranging between 0% and 45%, and this is associated with significant morbidity and mortality, prolonged hospital stay and increased hospital costs.This article compares and discusses the differences in rates of EVD CSF infection between clinical neurosurgical practice and the infection rates in a group of research patients where EVDs were sampled frequently as part of the study. ⋯ Sampling or irrigating ventricular drainage systems does not increase the risk of CNS infection providing the operator has appropriate experience and has used theatre standard aseptic technique.
