Do we really need 24-h observation for patients with minimal brain injury and small intracranial bleeding? The Bernese Trauma Unit Protocol

Traumatic brain injury is one of the most common reasons for admission to hospital emergency departments. However, optimal diagnosis and treatment protocols remain controversial. The aim of this study is to assess whether a specific group of patients can be discharged from the hospital without 24-h neurological observation.

Increasing hematocrit above 28% during early resuscitative phase is not associated with decreased mortality following severe traumatic brain injury

To prevent iatrogenic damage, transfusions of red blood cells should be avoided. For this, specific and reliable transfusion triggers must be defined. To date, the optimal hematocrit during the initial operating room (OR) phase is still unclear in patients with severe traumatic brain injury (TBI). We hypothesized that hematocrit values exceeding 28%, the local hematocrit target reached by the end of the initial OR phase, resulted in more complications, increased mortality, and impaired recovery compared to patients in whom hematocrit levels did not exceed 28%.

Long-Term outcome in patients with mild traumatic brain injury: A prospective observational study

Mild traumatic brain injury (MTBI) is common; up to 37% of adult men have a history of MTBI. Complaints after MTBI are persistent headaches, memory impairment, depressive mood disorders, and disability. The reported short- and long-term outcomes of patients with MTBI have been inconsistent. We have now investigated long-term clinical and neurocognitive outcomes in patients with MTBI (at admission, and after 1 and 10 years).

Co2-dependent vasomotor reactivity of cerebral arteries in patients with severe traumatic brain injury: time course and effect of augmentation of cardiac output with dobutamine

Failing cerebral blood flow (CBF) autoregulation may contribute to cerebral damage after traumatic brain injury (TBI). The purpose of this study was to describe the time course of CO(2)-dependent vasoreactivity, measured as CBF velocity in response to hyperventilation (vasomotor reactivity [VMR] index). We included 13 patients who had had severe TBI, 8 of whom received norepinephrine (NE) based on clinical indication. In these patients, measurements were also performed after dobutamine administration, with a goal of increasing cardiac output by 30%. Blood flow velocity was measured with transcranial Doppler ultrasound in both hemispheres. All patients except one had an abnormal VMR index in at least one hemisphere within the first 24 h after TBI. In those patients who did not receive catecholamines, mean VMR index recovered within the first 48 to 72 h. In contrast, in patients who received NE within the first 48 h period, VMR index did not recover on the second day. Cardiac output and mean CBF velocity increased significantly during dobutamine administration, but VMR index did not change significantly. In conclusion, CO(2) vasomotor reactivity was abnormal in the first 24 h after TBI in most of the patients, but recovered within 48 h in those patients who did not receive NE, in contrast to those eventually receiving the drug. Addition of dobutamine to NE had variable but overall insignificant effects on CO(2) vasomotor reactivity.

Diagnosis and treatment of an obsessive-compulsive disorder following traumatic brain injury: A single case and review of the literature

A 27-year-old patient with traumatic brain injury and neuropsychiatric symptoms fitting the obsessive-compulsive disorder was investigated. Brain CT-scan revealed left temporal and bilateral fronto-basal parenchymal contusions. Main Outcome Measure was the Yale-Brown Obsessive Compulsive Scale at pre- and post-treatment and at 6 months follow-up. The combination of pharmacotherapy and psychotherapy resulted in lower intensity and frequency of symptoms. Our case illustrates the importance of a detailed diagnostic procedure in order to provide appropriate therapeutic interventions. Further studies are needed to guide the clinician in determining which patients are likely to benefit from a psychotherapeutic intervention in combination with pharmacotherapy.

Trunk sway in patients with and without, mild traumatic brain injury after whiplash injury

This study assessed the addition effect of mild traumatic brain injury (MTBI) on the balance control of patients who simultaneously suffered a whiplash associated disorder (WAD).
