Meta AnalysisThe Efficacy of Low-Titer Group O Whole Blood Compared With Component Therapy in Civilian Trauma Patients: A Meta-Analysis.
To assess if transfusion with low-titer group O whole blood (LTOWB) is associated with improved early and/or late survival compared with component blood product therapy (CT) in bleeding trauma patients. ⋯ These data suggest hemostatic resuscitation with LTOWB compared with CT improves early and late survival outcomes in bleeding civilian trauma patients. The majority of subjects were injured adults; multicenter randomized controlled studies in injured adults and children are underway to confirm these findings.

Complex regional pain syndrome (CRPS) presents postinjury with disproportionate pain and neuropathic, autonomic, motor symptoms, and skin texture affection. However, the origin of these multiplex changes is unclear. Skin biopsies offer a window to analyze the somatosensory and vascular system as well as skin trophicity with their protecting barriers. ⋯ Barrier proteins in keratinocytes, perineurium of dermal nerves, Schwann cells, and papillary microvessels were not affected in early CRPS. Bilateral changes in the tissue architecture in early CRPS might indicate a predisposition for CRPS that manifests after injury. Further studies should evaluate whether these changes might be used to identify risk patients for CRPS after trauma and as biomarkers for outcome.

Conventional rapid thrombelastography (rTEG) cannot differentiate fibrinolysis shutdown from hypofibrinolysis, as both of these patient populations have low fibrinolytic activity. Tissue plasminogen activator (tPA) TEG can identify depletion of fibrinolytic inhibitors, and its use in combination with rTEG has the potential to differentiate all 3 pathologic fibrinolytic phenotypes after trauma. We hypothesize tPA-TEG and rTEG in combination can further stratify fibrinolysis phenotypes postinjury to better stratify risk for mortality. ⋯ The combination of rTEG and tPA-TEG increases the ability to predict mortality and suggests patient-specific strategies for improved outcomes.

The purpose of this surgical perspective is to describe the trauma care needs of the South Side of Chicago and the creation of an adult trauma center at the University of Chicago Medicine and associated hospital-based violence intervention program. ⋯ The persistent efforts of the community and key stakeholders led to a system change that improved trauma care for the South Side of Chicago.
