Comparative Study
Treatment of clavicular aseptic nonunion: comparison of plating and intramedullary nailing techniques.
The aim of this retrospective study was to investigate and compare the effects of plating and intramedullary nailing in the treatment of clavicular aseptic nonunion. ⋯ Intramedullary nailing may have a higher union rate with a lower complication rate than plating (p > 0.05). At least in common situations, it is not inferior to plating. Whenever possible, therefore, intramedullary nailing should be used preferentially to treat clavicular aseptic nonunion without previous operative treatment. Nevertheless, both techniques have relatively higher nonunion rates in the treatment of clavicular nonunion than in the treatment of other long-bone nonunions. Gentle handling of surrounding soft tissues to reduce bony fragments should be strictly executed.

Tachycardia is considered a physiologic response to traumatic hypotension. The inability of the heart to respond to shock with tachycardia has been described as paradoxical bradycardia or relative bradycardia. The incidence and clinical significance of this condition in major trauma is not known. The objective of this study was to examine the incidence and prognostic significance of tachycardia and relative bradycardia in patients with traumatic hypotension. Relative bradycardia is defined as a systolic pressure < or = 90 mm Hg and a pulse rate < or = 90 beats per minute. ⋯ Relative bradycardia in hypotensive trauma patients is a common hemodynamic finding. Mortality among tachycardic patients was more predictable than among bradycardic patients using commonly used demographic and injury indicators. The presence of relative bradycardia in some subgroups of patients with severe injuries seems to be associated with better prognosis than the presence of tachycardia.

Trauma patients with multiple extremity injuries (MEI) make heavy demands on hospital resources and face long-term difficulties in rehabilitation, yet the literature contains little about their treatment as a distinct group. ⋯ The study emphasizes the need for injury scoring systems that better predict the needs of patients with MEI and that will serve as a basis for equitable funding of trauma centers.

It is essential to identify patients at high risk of death and complications for future studies of interventions to decrease reperfusion injury. ⋯ Hemorrhage-induced hypotension in trauma patients is predictive of high mortality (54%) and morbidity. The requirement for large volumes of crystalloid was associated with increased mortality.

Hemoglobin-based blood substitutes may cause vasoconstriction, which could limit organ perfusion during trauma resuscitation. We investigated the effect of two hemoglobin solutions on regional blood flow and mucosal perfusion in the gastrointestinal tract in a hemorrhagic shock model. ⋯ PHP was efficacious in restoring CI and small-bowel flow, but the pHi remained low, indicating possible continued mucosal ischemia. Alpha(alpha)Hb led to limited recovery of CI and small-bowel blood flow but restored pHi close to baseline. Shed blood was efficacious in restoration of pHi, gastrointestinal blood flows, and systemic hemodynamics.
