Multicenter Study
Effect of high product ratio massive transfusion on mortality in blunt and penetrating trauma patients.
Recent data suggest that massively transfused patients have lower mortality rates when high ratios (>1:2) of plasma or platelets to red blood cells (RBCs) are used. Blunt and penetrating trauma patients have different injury patterns and may respond differently to resuscitation. This study was performed to determine whether mortality after high product ratio massive transfusion is different in blunt and penetrating trauma patients. ⋯ Use of high plasma:RBC ratios during massive transfusion may benefit penetrating trauma patients to a greater degree than blunt trauma patients. High platelet:RBC ratios did not benefit either group.

Gender-based differences in mortality in response to high product ratio massive transfusion.
Recent data suggest that patients undergoing massive transfusion have lower mortality rates when ratios of plasma and platelets to red blood cells (RBCs) of ≥ 1:2 are used. This has not been examined independently in women and men. A gender dichotomy in outcome after severe injury is known to exist. This study examined gender-related differences in mortality after high product ratio massive transfusion. ⋯ Use of high plasma:RBC or platelet:RBC ratios in massive transfusion may benefit men more than women. This may be due to gender-related differences in coagulability. Further study is needed to determine whether separate protocols for women and men should be established.

The process of returning to work (RTW) after multiple injuries is lengthy. Prospective studies with follow-up times of up to 5 years are necessary but lacking. The aim of this study was to describe the trajectory of RTW and to examine the factors that predicted RTW over 5 years for patients with multiple injuries using a prospective cohort design. ⋯ Of the patients included in this study, 49% achieved RTW, and 23% received full disability benefits. Higher education; better physical, social, and cognitive functioning; and coping strategies all predicted RTW.

Comparative Study
Canadian Cervical Spine rule compared with computed tomography: a prospective analysis.
The Canadian cervical spine rule (CCS) has been found to be an effective tool to determine the need for radiographic evaluation of the cervical spine (c-spine) incorporating both clinical findings and mechanism. Previously, it has been validated only through clinical follow-up or selective use of X-rays. The purpose of this study was to validate it using computed tomography (CT) as the gold standard to identify fractures. ⋯ CCS is very sensitive but not very specific to determine the need for radiographic evaluation after blunt trauma. Based on this study, the rule should be streamlined to improve specificity while maintaining sensitivity.

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.
