Comparative Study
Evaluation of hyperviscous fluid resuscitation in a canine model of hemorrhagic shock: a randomized, controlled study.
Enhancing plasma viscosity during fluid resuscitation results in vasodilation and improved microvascular perfusion in rodents subjected to hemorrhagic shock. We hypothesized that resuscitation with hyperviscous lactated Ringer's solution (hyperLRS) would result in improved tissue oxygenation and acid-base values in hemorrhaged dogs. ⋯ A hyperviscous balanced electrolyte solution did not improve hemodynamic parameters, tissue oxygen tension, or acid-base values despite evidence for viscosity-induced vasodilation.

Acute shortening is reported to be an effective method for the treatment of open fractures with bone and soft tissue defects. Little is known about primary skin closure with angulation to the side of the defect and distraction at the fracture site. ⋯ Angular compression to the side of the defect is a safe and reliable method of treatment for asymmetrical bone or soft tissue defects of tibia. It eliminates the need for complex soft tissue reconstruction procedures. Unnecessary debridement of bone is prevented by angular adaptation of edges. Definitive treatment of complex injuries is possible with a circular external fixator.

The treatment of unstable fractures of the distal radius remains controversial between nonoperative and operative management and between different methods of internal and external fixation. The aim of the study is to evaluate the early functional and radiologic outcomes of using Association for the Study of Osteosynthesis (AO) (Synthes) distal radius volar locking plate for unstable dorsally displaced distal radius fractures. ⋯ This report supports the view of using volar plating for the unstable dorsally displaced distal radius fractures.
