Improvements in trauma systems and resuscitation have increased survival in severely injured patients. Massive transfusion has been increasingly used in the civilian setting. Objective predictors of mortality have not been well described. This study examined data available in the early postinjury period to identify variables that are predictive of 24-hour- and 30-day mortality in massively transfused trauma patients. ⋯ Glasgow Coma Scale score, pH, heart rate, age, Injury Severity Score, and 6-hour red blood cell transfusion requirement independently predict mortality in massively transfused trauma patients. Models incorporating these data have only a modest ability to predict mortality and should not be used to justify withholding massive transfusion in individual cases.

Acute cervical spinal cord injury (cSCI) is associated with significant morbidity and mortality. Vertebral level and American Spinal Injury Association (ASIA) score influence both hospital course and ultimate outcome. While controlling for these variables, we describe the effect of age on cSCI-related pneumonia and mortality. ⋯ Age was associated with an increase in mortality among patients with an acute cSCI. Injury level and ASIA score contributed significantly to overall pneumonia rate and mortality at all ages; however, pneumonia did not correlate directly with mortality in this population. Other factors play a role in the mortality associated with geriatric spinal cord-injured patients, including end-of-life decision making; these need to be investigated further in future studies.

The natural history and optimal treatment of upper extremity (UE) deep venous thromboses (DVT's) remains uncertain as does the clinical significance of catheter-associated (CA) UE DVT's. We sought to analyze predictors of UE DVT resolution and hypothesized that anticoagulation will be associated with quicker UE DVT clot resolution and that CA UE DVT's whose catheters are removed will resolve more often than non-CA UE DVT's. ⋯ A majority of UE DVT's are CA, more than half resolve before discharge, and 2% embolize. Anticoagulation does not appear to affect outcomes, but line removal does result in a quicker decrease in clot size.

Improvements in prehospital care and resuscitation have led to increases in the number of severely injured patients who are salvageable. Massive transfusion has been increasingly used. Patients often present with markedly abnormal physiologic and biochemical data. The purpose of this study was to identify objective data that can be used to identify clinical futility in massively transfused trauma patients to allow for early termination of resuscitative efforts. ⋯ Consideration should be given to withholding massive transfusion for patients older than 65 years with severe head injuries. Otherwise we did not identify any objective variables that reliably predict clinical futility in individual cases. Significant survival rates can be expected even in patients with profoundly abnormal physiologic and biochemical data.

Comparative Study
Cost-utility analysis of levetiracetam and phenytoin for posttraumatic seizure prophylaxis.
The standard for early posttraumatic brain injury (TBI) seizure prophylaxis is phenytoin. Despite its effectiveness, some argue for the use of newer antiepileptics (e.g., levetiracetam) because phenytoin requires close monitoring to maintain its therapeutic window and is associated with rare cutaneous hypersensitivity reactions. The purpose of this study was to evaluate whether phenytoin or levetiracetam would be more cost-effective in preventing early post-TBI seizures and reducing their negative impact on TBI outcomes. ⋯ Phenytoin is more cost-effective than levetiracetam at all reasonable prices and at all clinically plausible reductions in post-TBI seizure potential.
