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.

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.

To demonstrate that patients with multiple injuries who have orthopedic injuries (ORTHO) face greater challenges regarding functional outcome than those without, to identify domains of postinjury dysfunction, and to illustrate the increasing discordance of functional recovery over time for ORTHO patients in relation to nonORTHO patients. ⋯ Injury severity affects both mortality and the potentially more consequential issues of long-term morbidity. Patients with ORTHO injury have relatively worse functional recovery, and this worsens with time. As trauma centers approach the limits of achievable survival, new advances in trauma care can be directed more toward the quality of recovery for our patients. This will be contingent on further development of screening, scoring, and treatment systems designed to address issues of functional outcome across injury boundaries for those who survive.

The purpose of this study was to evaluate the indication for routine cervical spine radiography in trauma patients. ⋯ It is within good practice, and it is also cost-effective, to obtain a cervical spine radiograph only on clinical parameters in trauma patients with no apparent bodily trauma and optimal parameters. With this clinical decision rule, 30.6% of all cervical spine series were redundant, and no (occult) spinal fractures would have been undetected.
