This study tests whether the hemostatic action of poly-N-acetyl glucosamine (p-GlcNAc) fiber material involves vasoconstrictor release leading to closure of an aortic laceration. ⋯ The mechanism of hemostasis by poly-N-acetyl glucosamine involves endothelin release independent of formed elements of blood.

Comparative Study
Application of the poly-N-acetyl glucosamine-derived rapid deployment hemostat trauma dressing in severe/lethal Swine hemorrhage trauma models.
The Rapid Deployment Hemostat (RDH) Bandage was developed for the rapid control of bleeding caused by trauma. ⋯ The RDH Bandage was superior to a commercially available fibrin bandage in controlling hemorrhage, decreasing blood loss, and increasing survival.

General mediastinal width, left mediastinal width, and mediastinal width ratio were compared as radiographic predictors of aortic injury. ⋯ Both an LMW of 6 cm or more and an MWR of 0.60 or more are better radiographic criteria than an MW of 8 cm or more for predicting blunt aortic injury. Trauma patients with positive test results based on the combined LMW and MWR criteria should proceed immediately to aortography or helical computed tomography.

Air transport of burn patients is plagued by frequent "overtriage." We examined the use of air transport and the feasibility of using alternative methods such as telemedicine to assist in evaluation and treatment of burn patients within our region. ⋯ Frequent discrepancies in burn assessment contribute to overuse of air transport. The ability to evaluate burn patients by telemedicine may have the potential to assist decisions regarding transfer, avoid errors in initial care, and reduce costs. We are currently attempting to develop and test such a system.

Nonmotorized scooters have increased rapidly in popularity over the past year. However, the morbidity associated with this new type of recreational vehicle is poorly defined. This study examined the pattern of scooter-related injuries sustained in children admitted to a level 1 pediatric trauma center. ⋯ Scooters are an increasingly popular form of recreational vehicle among children. However, they can result in serious injury, particularly to the head and extremities. The authors recommend that all children riding scooters wear protective equipment and avoid riding in areas that have moving motor vehicles.
