TL;DR: Higher plasma and platelet ratios early in resuscitation were associated with decreased mortality in patients who received transfusions of at least 3 units of blood products during the first 24 hours after admission, and among survivors at 24 hours, the subsequent risk of death by day 30 was not associated with plasma or Platelet ratios.
Journal ArticleDOI
Prehospital Plasma during Air Medical Transport in Trauma Patients at Risk for Hemorrhagic Shock.

TL;DR: In injured patients at risk for hemorrhagic shock, the prehospital administration of thawed plasma was safe and resulted in lower 30‐day mortality and a lower median prothrombin‐time ratio than standard‐care resuscitation.
Journal ArticleDOI
An FFP:PRBC transfusion ratio >/=1:1.5 is associated with a lower risk of mortality after massive transfusion.
Jason L. Sperry,Juan B. Ochoa,Scott R. Gunn,Louis H. Alarcon,Joseph P. Minei,Joseph Cuschieri,Matthew R. Rosengart,Ronald V. Maier,Timothy R. Billiar,Andrew B. Peitzman,Ernest E. Moore +10 more
TL;DR: In patients requiring>/=8 units of blood after serious blunt injury, an FFP:PRBC transfusion ratio >/=1:1.5 was associated with a significant lower risk of mortality but a higher risk of acute respiratory distress syndrome, providing further justification for the prospective trial investigation into the optimal FFP-PRBC ratio required in massive transfusion practice.
Journal ArticleDOI
Clinical and mechanistic drivers of acute traumatic coagulopathy.
Mitchell J. Cohen,Matthew E. Kutcher,Britt J. Redick,Mary F. Nelson,Mariah Call,M. Margaret Knudson,Martin A. Schreiber,Eileen M. Bulger,Peter Muskat,Louis H. Alarcon,John G. Myers,Mohammad H. Rahbar,Karen J. Brasel,Herb A. Phelan,Deborah J. Del Junco,Erin E. Fox,Charles E. Wade,John B. Holcomb,Bryan A. Cotton,Nena Matijevic +19 more
TL;DR: ATC is associated with the depletion of factors I, II, V, VII, VIII, IX, and X and is driven by the activation of the protein C system and further understanding of the drivers of ATC and the effects of resuscitation can guide factor-guided resuscitation and correction of coagulopathy after injury.
Journal ArticleDOI
Operative fixation of rib fractures after blunt trauma: A practice management guideline from the Eastern Association for the Surgery of Trauma

TL;DR: In adult patients with flail chest, this project conditionally recommend rib ORIF to decrease mortality; shorten DMV, hospital LOS, and ICU LOS; and decrease incidence of pneumonia and need for tracheostomy.
