Randomized Controlled Trial
Abnormal coagulation tests are associated with progression of traumatic intracranial hemorrhage.
Intracranial hemorrhage (ICH) is common in traumatic brain injury (TBI) and a major determinant of death and disability. ICH commonly increases in size and coagulopathy has been implicated in such progression. We investigated the association between coagulopathy diagnosed by routine laboratory tests and ICH progression. ⋯ This study demonstrates an association between coagulopathy, diagnosed by routine laboratorial tests in the first 24 hours, with ICH progression; and ICH progression with mortality in patients with severe TBI. The causal relationship between coagulopathy and ICH progression will require further studies.

Multicenter Study
Relative bradycardia in hypotensive trauma patients: a reappraisal.
The inability to mount tachycardia (T) after trauma-related hypotension is labeled relative bradycardia (RB). The objective of this study was to examine RB incidence and prognosis in a large cohort of patients. ⋯ RB was common in hypotensive adult trauma patients; overall, it was associated with increased mortality. Patients older than 55 years and with a higher Glasgow coma scale score demonstrated decreased mortality with RB. When RB was further divided, a HR between 60 and 90 demonstrated a significant lower mortality compared with a HR <60 and to T.

Blunt cerebrovascular injuries (BCVI) in trauma patients are rare but potentially devastating injuries, particularly if the diagnosis is delayed. Conventional angiography (CA) has been the screening and diagnostic modality of choice for identifying BCVI. With the advent of high-resolution computed tomography (CT), CT angiography has become a common modality for the screening of BCVI. A liberalized screening approach has suggested that cerebrovascular injuries are missed in many patients; however, no standard BCVI screening protocol exists. Early diagnosis of the BCVI can prevent long-term sequelae. ⋯ Neither 16- nor 64-slice CT angiography is as accurate as CA as a screening tool for BCVI.
