Trauma-related morbidity and mortality are a growing burden in the developing world. However, usable injury data in resource-poor and developing settings is lacking. Trauma registries can improve injury surveillance to enhance trauma care, outcomes, and prevention. This article provides, by example from Haiti, an approach to developing a hospital-based trauma registry in a resource-poor setting. ⋯ Trauma registries in developing settings are plausible tools for injury surveillance. Successful trauma registries will be resource- and setting-specific in design and can potentially be the means by which trauma care and outcomes are improved, prevention programs are developed, and capacity-building goals realized.

Comparative Study
Range-of-motion restriction and craniofacial tissue-interface pressure from four cervical collars.
Occipital pressure ulcers are well-known complications for trauma patients wearing cervical collars. We assessed the effects of four commercial cervical collars (Aspen, Philadelphia, Miami J, and Miami J with Occian back [Miami J/Occian]) on cervical range of motion (CROM) and mandibular and occipital tissue-interface pressure (TIP). ⋯ Miami J and Philadelphia collars restricted CROM to the greatest extent. Miami J and Miami J/Occian back had the lowest levels of mandibular and occipital pressure; these collars may markedly reduce the risk of occipital pressure ulcers without compromising immobilization.

To measure the combined contribution of change in velocity (Deltav), principal direction of force (PDOF), and restraint use on mortality after vehicular trauma. ⋯ A Deltav 40 km/h to 80 km/h, lack of restraint use, and lateral impact significantly affects mortality. A synergistic effect was found between Deltav 40-80 km/h and lateral PDOF.

It is widely accepted that all-terrain vehicles (ATVs) can be dangerous to operators. Understanding the mechanisms of ATV crashes, especially rollovers, can provide important insight to consumers, legislators, and manufacturers on ATV safety and protection of the users. ⋯ These findings suggest that nonrandom, modifiable factors are likely involved. Our data provide unique insight into specific mechanisms of ATV crashes, particularly rollovers, and those involving children. Findings may be applicable to changes in ATV design and education of users.

Comparative Study
In vitro effect of activated recombinant factor VII (rFVIIa) on coagulation properties of human blood at hypothermic temperatures.
Recombinant activated factor VII (rFVIIa) is currently administered off-label to control diffuse coagulopathic bleeding of patients with traumatic injuries. These patients are often cold, acidotic, and coagulopathic upon arrival and each responds differently to rFVIIa therapy. This study investigated the effects of hypothermia on clotting and the potential benefit of rFVIIa administration on blood coagulation at different hypothermic temperatures. ⋯ Mild to moderate hypothermia delayed the initial clot reaction and reduced clot formation rate without affecting ultimate clot strength. FVIIa effectively compensated for the adverse effects of hypothermia except in severe cases. These results suggest that administration of FVIIa should be beneficial in enhancing hemostasis in hypothermic trauma patients without the need for prior correction of the patient's body temperature.
