There is controversy about the effect of certain drugs on cystatin C (CysC) concentrations, which would limit the usability of CysC for estimation of glomerular filtration rate (GFR) in patients with renal disease. Seventy-one children (ages 2.6 months to 18 years) with renal disease and on at least one study medication (tacrolimus, cyclosporine,(More)
BACKGROUND Near-infrared spectroscopy estimates soft-tissue oxygenation approximately 2 to 3 cm below the skin. The purpose of the present study was to evaluate muscle oxygenation in the setting of an acute compartment syndrome of the leg and to determine if near-infrared spectroscopy is capable of detecting perfusion deficits. METHODS Fourteen patients(More)
BACKGROUND Near-infrared spectroscopy measures the percentage of hemoglobin oxygen saturation in the microcirculation of tissue up to 3 cm below the skin. The purpose of this study was to describe the measurable response of normal tissue oxygenation in the leg after acute trauma with use of this technique. METHODS Twenty-six patients with acute unilateral(More)
OBJECTIVES The objective of this study is to analyze the effect of an orthopaedic trauma advanced practice provider on length of stay (LOS) and cost in a level I trauma center. The hypothesis of this study is that the addition of a single full-time nurse practitioner (NP) to the orthopaedic trauma team at a level I Trauma center would decrease overall LOS(More)
BACKGROUND Near infrared spectroscopy (NIRS) has been suggested as a possible means for detecting perfusion deficits in patients with acute compartment syndrome (ACS). STUDY OBJECTIVES To longitudinally examine NIRS in an ACS model to determine its responsiveness to decreasing perfusion pressure. METHODS A NIRS sensor pad was placed under a tourniquet(More)
Pelvic ring fractures often result in severely injured patients with multiple organ injuries. The most common associated injuries are intraabdominal or urogenital, and urogenital injuries are the most common associated injuries in those with severe pelvic fractures. Prompt and effective diagnosis and management of these injuries is essential to successful(More)
BACKGROUND Despite extensive research regarding patient outcomes after operative fixation of humeral shaft fractures by means of open reduction and internal fixation (ORIF) or intramedullary nailing (IMN), no current consensus exists regarding the optimal surgical treatment. The objective of this study was to compare IMN and plate fixation (ORIF) of humeral(More)
BACKGROUND Acute compartment syndrome is a rare but serious consequence of traumatic leg injury. Near-infrared spectroscopy (NIRS) is able to measure oxygenation to a depth of 2 cm to 3 cm below the skin, raising concerns over the ability of NIRS to accurately determine oxygenation of injured leg compartments in the presence of swelling and in the obese.(More)
The purpose of this study was to test and compare external fixator construct stiffness using pin-to-bar clamps or multipin clamps across 2 external fixation systems. Constructs were tested with 8-mm and 11-mm-diameter bar systems and pin-to-bar or multipin clamps. Three construct designs were tested: construct 1 with a single crossbar and pin-to-bar clamps,(More)
