Randomized Controlled Trial Multicenter Study Clinical Trial
Computerized decision support for mechanical ventilation of trauma induced ARDS: results of a randomized clinical trial.
Variability and logistic complexity of mechanical ventilatory support of acute respiratory distress syndrome, and need to standardize care among all clinicians and patients, led University of Utah/LDS Hospital physicians, nurses, and engineers to develop a comprehensive computerized protocol. This bedside decision support system was the basis of a multicenter clinical trial (1993-1998) that showed ability to export a computerized protocol to other sites and improved efficacy with computer- versus physician-directed ventilatory support. The Memorial Hermann Hospital Shock Trauma intensive care unit (ICU) (Houston, TX; a Level I trauma center and teaching affiliate of The University of Texas Houston Medical School) served as one of the 10 trial sites and recruited two thirds of the trauma patients. Results from the trauma patient subgroup at this site are reported to answer three questions: Can a computerized protocol be successfully exported to a trauma ICU? Was ventilator management different between study groups? Was patient outcome affected? ⋯ A computerized protocol for bedside decision support was successfully exported to a trauma center, and effectively standardized mechanical ventilatory support of trauma-induced acute respiratory distress syndrome without adverse effect on patient outcome.

Randomized Controlled Trial Comparative Study Clinical Trial
RAB-plate versus sliding hip screw for unstable trochanteric hip fractures: stability of the fixation and modes of failure--radiographic analysis of 218 fractures.
The sliding hip screw has gained considerable acceptance in the treatment of unstable trochanteric fractures. However, the new type of 120 degrees fixed angle blade-plate with a buttress rod (RAB-plate) showed encouraging clinical results. The purpose of this study was to assess stability of fixation and analyze modes of failure in unstable trochanteric hip fractures treated with these devices. ⋯ The RAB-plate provided a more stable fixation, especially with regard to maintained postoperative alignment. However, positive predictors for fixation failure were identical for both devices. Here, the screw/neck angle deviation has had the strongest significance for prediction of fixation failure.

Chest radiographs are routinely obtained for the identification of pneumothoraces in trauma patients. Computed tomographic (CT) scanning has a higher sensitivity for the detection of pneumothoraces, but the prevalence and importance of pneumothoraces detectable by CT scan but not by chest radiography in children sustaining blunt trauma is unclear. ⋯ Less than half of pediatric blunt trauma patients with pneumothoraces visualized on abdominal CT scan had these pneumothoraces identified on initial chest radiograph. Patients with pneumothoraces identified solely on abdominal CT scan, however, uncommonly require tube thoracostomy.

The potential for ligamentous injury of the cervical spine (C-spine) may mandate prolonged neck immobilization via a hard cervical collar in the blunt trauma victim (BTV) with altered sensorium. We investigated the incidence of ligamentous C-spine injuries, and whether applying (post hoc) the practice management guidelines from the Eastern Association for the Surgery of Trauma (three radiograph views plus computed tomographic scan of C1-C2) would have detected the injuries. ⋯ Ligamentous injuries without fracture of the C-spine are rare. Application of the practice management guidelines developed by the Eastern Association for the Surgery of Trauma for identifying C-spine instability is effective and should facilitate early removal of the cervical collar in unreliable patients.

An investigation of the experiences of parents grieving the traumatic death of their child, the initiatives that helped, and common parental concerns that would benefit from improved education. ⋯ We conclude that parents' unanswered questions or misconceptions regarding brain death, organ donation, and their child's medical care adversely affect their grief; that "normal life" for parents is challenged as they struggle to establish a new sense of normal; and that hospital and trauma service personnel can positively impact the grieving process with appropriate training.
