The use of Hypertonic Saline in the Treatment of Post-Traumatic Cerebral Edema: A Review.
Effective methods for treating cerebral edema have recently become a matter of both extensive research and significant debate within the neurosurgery and trauma surgery communities. The pathophysiologic progression and outcome of different forms of cerebral edema associated with traumatic brain injury have yet to be fully elucidated. There are heterogeneous factors influencing the onset and progress of post-traumatic cerebral edema, including the magnitude and type of head injury, age, co-morbid conditions of the patient, the critical window for therapeutic intervention and the presence of secondary insults including hypoxia, hypotension, hypo/hyperthermia, degree of raised intracranial pressure (ICP), and disruption of blood brain barrier (BBB) integrity. ⋯ More recently, fluid resuscitation strategies using hyperosmolar agents such as pentastarch and hypertonic saline (HS) have achieved some success. HS treatment is of particular interest due to its apparent advantageous action over other types of hyper-osmotic solutions in both clinical and laboratory studies. In this review, we provide a summary of recent literature concerning the pathogenesis and mechanisms involved in the various types of cerebral edema, and the possible mechanisms of action of HS for the treatment cerebral edema.

An estimated 300,000 sport-related traumatic brain injuries, predominantly concussions, occur annually in the United States. Sports are second only to motor vehicle crashes as the leading cause of traumatic brain injury among people aged 15 to 24 years. ⋯ Sport-related injury surveillance systems can provide scientific data to drive targeted injury-prevention projects. Developing effective sport-related concussion preventive measures depends upon increasing our knowledge of concussion rates, patterns, and risk factors.

Early Placement of Optional Vena Cava Filter in High-Risk Patients with Traumatic Brain Injury.
Patients sustaining severe trauma are at high risk for the development of venous thromboembolic events (VTE). Pharmacologic VTE prophylaxis may be contraindicated early after trauma due to potential bleeding complications. The purpose of this study was to evaluate safety and feasibility of early prophylactic vena cava filter (VCF) placement and subsequent retrieval in multiple injured patients with traumatic brain injury (TBI). ⋯ Early VCF placement may be of benefit for multiple injured patients with TBI when pharmacologic VTE prophylaxis is contraindicated. VCF retrieval is safe and feasible. Filter placement- and retrieval-related morbidity is low.

Cervical spine injury occurs in 5-10% of patients with traumatic brain injury (TBI) and the consequences of missing significant cervical injuries in unconscious blunt trauma patients are potentially devastating. An adequate cervical spine clearance protocol for unconscious patients must avoid missed injuries, but must also avoid unnecessary cervical immobilisation and the associated morbidity. Existing protocols include various combinations of plain X-rays, helical CT, dynamic flexion-extension X-rays and MRI. ⋯ Nevertheless, recently at The Alfred Hospital, extremely high-risk TBI patients have had unstable cervical injuries detected solely by MRI. Current generation multi-slice CT with reconstructions may obviate the need for MRI even in these patients. The current Alfred Hospital cervical clearance protocol for unconscious patients, and the evolutionary steps in its development, will be discussed.

Neurorehabilitation and cognitive-behaviour therapy of anxiety disorders after brain injury: An overview and a case illustration of obsessive-compulsive disorder.
Survivors of acquired and traumatic brain injuries may often experience anxiety states. Psychological reactions to neurological trauma may be caused by a complex interaction of a host of factors. We explore how anxiety states may be understood in terms of a biopsychosocial formulation of such factors. ⋯ We show how CBT plus CR allows a biopsychosocial formulation to be developed of the survivor's concerns for guiding a goal-based intervention. The survivor made significant gains from intervention in terms of goals achieved and changes on clinical measures. We argue that large-scale research is needed for developing an evidence base for managing emotional disorders in brain injury.
