Comparative Study
Midterm effects of fluid resuscitation strategies in an experimental model of lung contusion and hemorrhagic shock.
This study compared three different fluid resuscitation strategies in terms of respiratory tolerance and hemodynamic efficacy in a pig model of blunt chest trauma with lung contusion and controlled hemorrhagic shock. We hypothesized that the choice of fluid resuscitation strategy (type and amount of fluids) may impact differently contused lungs in terms of extravascular lung water (EVLW) 20 h after trauma. ⋯ This study demonstrated the impact of fluid resuscitation on contused lungs. Twenty hours after the trauma, all three resuscitation approaches showed modest clinical consequences, with moderate lung edema and reduced compliance in response to the infused volume.

Traumatic asphyxia is a rare condition in children that usually occurs after severe compression to the chest or abdomen. We report 3 cases in patients 18, 20, and 36 months of age who presented signs and symptoms of traumatic asphyxia after car accidents. ⋯ In children, the number of clinical manifestations that should be evident to diagnose traumatic asphyxia has not been ascertained. However, in any history of trauma with compression of the chest or abdomen and signs of increased intravenous craniocervical pressure, traumatic asphyxia should be suspected.

Equine-associated maxillofacial injuries: retrospective 5-year analysis.
We explored the relation between the causes of facial injuries in equestrians and the presence or absence of associated injuries. Over a 5-year period we retrospectively reviewed all patients who presented to the John Hunter Hospital, New South Wales, with facial injuries that had resulted from activity with horses. We analysed the rates of hard and soft tissue injuries, and of associated injuries by sex and mechanism. ⋯ Women who had been kicked by a horse were more likely to sustain bony injuries than men (p<0.05). Our data confirm the association between kicks and facial fracture, and this may provide an impetus for the development of appropriate protective equipment. Patients who sustain facial injuries when falling from a horse often present with associated injuries and this has practical implications for clinicians involved in their management.

Anatomical manifestations of primary blast ocular trauma observed in a postmortem porcine model.
We qualitatively describe the anatomic features of primary blast ocular injury observed using a postmortem porcine eye model. Porcine eyes were exposed to various levels of blast energy to determine the optimal conditions for future testing. ⋯ These data provide evidence that primary blast alone (in the absence of particle impact) can produce clinically relevant ocular damage in a postmortem model. The blast parameters derived from this study are being used currently in an in vivo model. We also propose a new Cumulative Injury Score indicating the clinical relevance of observed injuries.

Case ReportsPosttraumatic superior ophthalmic vein thrombosis in a 2 year old.
Superior ophthalmic vein thrombosis (SOVT) usually results from inflammatory, infectious, or malignant causes. This case describes a 2-year-old boy with severe prolapsing chemosis and proptosis due to thrombosis of the right superior ophthalmic vein resulting from midfacial and right orbital fractures 1 week after the initial trauma. Magnetic resonance imaging and internal carotid artery angiogram are essential in the diagnosis of SOVT. The literature on issues surrounding this case was reviewed with emphasis on the diagnostic evaluation, differential diagnoses, and management of posttraumatic SOVT.
