Multicenter Study
Increased platelet:RBC ratios are associated with improved survival after massive transfusion.
Several recent military and civilian trauma studies demonstrate that improved outcomes are associated with early and increased use of plasma-based resuscitation strategies. However, outcomes associated with platelet transfusions are poorly characterized. We hypothesized that increased platelet:red blood cells (RBC) ratios would decrease hemorrhagic death and improve survival after massive transfusion (MT). ⋯ Similar to recently published military data, transfusion of platelet:RBC ratios of 1:1 was associated with improved early and late survival, decreased hemorrhagic death and a concomitant increase in multiple organ failure-related mortality. Based on this large retrospective study, increased and early use of platelets may be justified, pending the results of prospective randomized transfusion data.

Randomized Controlled Trial
A pilot study on the randomization of inferior vena cava filter placement for venous thromboembolism prophylaxis in high-risk trauma patients.
Placement of prophylactic inferior vena cava filters (pIVCFs) for the prevention of pulmonary embolism (PE) in high-risk trauma patients (HRTPs) are widely practiced despite the lack of Level I data supporting this use. We report the 2-year interim analysis of the Filters in Trauma pilot study. ⋯ Our pilot study demonstrates for the first time that a randomized controlled trial evaluating the efficacy of pIVCFs in trauma patients is feasible. This pilot data will be used to inform the design of a multicenter randomized controlled trial to determine the incidence of PE and DVT in HRTPs receiving pIVCFs versus no pIVCF.

Infection is an all-too-common complication of combat-related injuries. The Prevention of Combat-Related Infections Guidelines Panel was established to review pertinent data that have become available since 2007 on prevention of these infections and to update guidelines by this group previously published in 2008. These updated guidelines, Guidelines for the Prevention of Infections Associated With Combat-related Injuries: 2011 Update, are published in this Journal of Trauma supplement along with evidence-based medicine reviews of the supporting data.

Bleeding often poses significant life-threatening situations to surgeons. After trauma, a one-third of civilian casualties and one-half of combat casualties die as a result of exsanguination. Recent advances have provided promising new hemostatic dressings that are applied directly to severely bleeding wounds in the pre-hospital period. ⋯ The mRDH trauma/surgery bandage was able to increase survival of patients after high-grade liver trauma with an associated coagulopathy. Additional clinical studies support this result.

Multicenter Study
Crystalloid resuscitation improves survival in trauma patients receiving low ratios of fresh frozen plasma to packed red blood cells.
Current trauma resuscitation guidelines recommend giving an initial crystalloid bolus as first line for resuscitation. Recent studies have shown a survival benefit for trauma patients resuscitated with high ratios of fresh frozen plasma (FFP) to packed red blood cells (PRBC). Our aim was to determine whether the volume of crystalloid given during resuscitation correlated with differences in morbidity or mortality based on the ratio of FFP:PRBC given. ⋯ If high ratios of FFP:PRBC are unable to be given to trauma patients, resuscitation with at least 1 L of crystalloid per unit of PRBC is associated with improved overall mortality.
