Randall M. Chesnut, M.D., from the University of Washington in Seattle, and colleagues conducted a multicenter trial involving 324 patients aged 13 years or older with severe TBI. The participants were randomly allocated to receive guidelines-based management, in which a protocol for monitoring intraparenchymal intracranial pressure was used, or a treatment protocol based on imaging and clinical examination.
The researchers observed no significant difference between the groups in the primary outcome, a composite measure based on 21 assessments of functional and cognitive status, and six-month mortality was also not significantly different between the groups (P = 0.60). There was no significant difference in the median length of stay in the intensive care unit between the groups, although the imaging-clinical examination group had a higher number of days of brain-specific treatments (4.8 versus 3.4; P = 0.002). There was a similar distribution of serious adverse events between the groups.
