“…Patients with severe traumatic brain injury are particularly prone to developing infections and sepsis because clinical symptoms and conventional markers are not always reliable indicators of infection in this patient group. Adding to this, patients with Glasgow Coma Scale scores less than nine (as is the case in severe TBI) have relatively higher rates of upper airway microbial colonisation (Feasal, El Azab, Mashhour, & El Hadidy, ), possible attributed to the aspiration of high inoculum oropharyngeal secretions immediately following brain injury, during resuscitation and as a result of intubation. The presence of long‐term invasive devices such as urinary catheters or intravenous cannulae compounds this risk (McClelland & Moxon, ).…”
