The purpose of this study was to evaluate risk factors for nonunion after femoral nailing of femoral shaft fractures. A case-control study with two to one matching was conducted. Forty-five patients with 46 femoral nonunions (cases) and 92 patients with healed femoral shaft fractures (controls) were identified from our orthopedic trauma registry. ⋯ The characteristics that were significantly different between the two groups were open fracture, delay to weight bearing, and tobacco use. Fracture classification, gender, direction of nail insertion (antegrade vs. retrograde), and Injury Severity Score were not predictive of nonunion. We conclude that open fracture, tobacco use, and delayed weight bearing are risk factors for femoral nonunion after intramedullary nailing for diaphyseal femur fractures.

Acute respiratory distress syndrome (ARDS) has been shown to increase morbidity but not mortality in trauma patients; however, little is known about the effects of ARDS in nontrauma surgical patients. The purpose of this study is to evaluate the risk factors for and outcomes of ARDS in nontrauma surgical patients. ⋯ Unlike trauma patients, ARDS was an independent predictor of ICU mortality in nontrauma surgical patients, independent of age and disease severity. Nontrauma surgical patients who developed ARDS were older, sicker, and had a longer ICU stay. Independent predictors of ARDS included use of pressors, sepsis, and obesity.

Trauma teams responsible for the first response to patients with multiple injuries upon arrival in a hospital consist of medical specialists or resident physicians. We hypothesized that 24-hour video registration in the trauma room would allow for precise evaluation of team functioning and deviations from Advanced Trauma Life Support (ATLS) protocols. ⋯ Video registration of diagnostic and therapeutic procedures by a multidisciplinary trauma team facilitates an accurate analysis of possible deviations from protocol. In addition to identifying technical errors, the role of the team leader can clearly be analyzed and related to team actions. Registration strongly depends on availability of video tapes, timely started registration, and hardware functioning. The results from this study were used to develop a training program for trauma teams in our hospital that specifically focuses on the team leader's functioning.

This study uses statistical predictive modeling and hierarchical cluster analyses to examine inflammatory mediators and cells in bronchoalveolar lavage (BAL) as putative biomarkers in rats with blunt trauma lung contusion (LC), gastric aspiration (combined acid and small gastric food particles, CASP), or a combination of the two. ⋯ These results support the possibility that inflammatory biomarker profiles could be developed in the future to improve the diagnosis and management of trauma patients with unwitnessed (occult) gastric aspiration who have an increased risk of clinical acute lung injury or the acute respiratory distress syndrome.
