In this study, we evaluated scaphoid X-series, Carpal Box radiographs (longitudinal and transverse), planar tomography, computed tomography (CT), and magnetic resonance imaging (MRI) in the diagnosis of scaphoid fracture. The aim of this study was to evaluate the planar technique in the diagnosis of scaphoid fracture. The use of planar tomography, CT, and MRI was to see whether these methods are useful in the diagnosis of scaphoid fracture when other diagnostics modalities remains negative. ⋯ From the planar investigated methods, the 15-degree Carpal Box posterior-anterior, longitudinal and transverse views were most accurate in recognizing scaphoid fracture with also the highest agreement between the observers.

Comparative Study
Use of recombinant hemoglobin solution in reversing lethal hemorrhagic hypovolemic oxygen debt shock.
To compare recombinant hemoglobin solution (rHb1.1) with colloid/blood (CB) resuscitation in a hemorrhagic shock (HS) model based on oxygen debt (O2D). ⋯ Lactate and BEA accurately quantify O2D in HS and resuscitation. rHb1.1 replacement is as good as CB with regard to survival, but leads to a more uniform reperfusion and produces a more complete resolution of ischemic acidosis.

To asses the feasibility and success rate of vascular access through intraosseous infusions in adults, in elective and emergency situations using a novel, automatic device, the bone injection gun. ⋯ This study emphasizes the importance and feasibility of the intraosseous route for infusion of fluids and medications in emergency situations in adults. The use of an impact, high speed automatic needle insertion device provides a higher success rate of vascular access via the intraosseal route in adult patients.

To test the hypothesis that protective-preservative moderate hypothermia during uncontrolled hemorrhagic shock (UHS) in rats increases survival. ⋯ Moderate hypothermia or limited (hypotensive) fluid resuscitation --best both combined--increases survival during and after UHS in rats.
