The Combat Ready Clamp (CRoC™) was designed to control hemorrhage from the groin region, on the battlefield. The purpose of this experiment was to determine whether CRoC™ user performance varied by the surface the casualty laid on (flat-hard, flat-soft, and curved-soft) and how quickly the device could be applied. The commercial manikin selected to assess user performance was designed to train soldiers in CRoC™ use. ⋯ Users were trained to use the Combat Ready Clamp effectively, and the surface the casualty was lying on made some difference to user performance. All six persons trained had success in all nine of their iterations of CRoC™ use- a 100% rate. These findings indicate that training was effective and that training of other users is plausible, feasible, and practical within the scope of the present evidence.

To determine the types of functional disabilities in adult and paediatric burns survivors, with specific emphasis on potential risk and socio-economic factors of burn disabilities present in Ghana. ⋯ The commonest functional disabilities recorded were scar contractions of the axilla region which had impeded the ability of the patients to lift the arm. Risk factors for burns disability included childhood age, third degree of burn incurred and anatomical part affected. Social factors influencing the lives of burn survivors with disability were good family and negative community interactions. Significant economical factors recorded were caretakers' time and financial constrains.

Coagulopathy can occur after hemorrhage, trauma and resuscitation, and has been associated with dilution of coagulation factors and hypothermia. Recombinant activated Factor VII (rFVIIa) has been used, often as a last resort, to improve hemostasis in trauma/hemorrhage patients with coagulopathy. The aim of this study was to further characterize the effects of rFVIIa on various coagulation parameters and the influence of temperature and hemodilution. ⋯ Theses data show that thrombin generation is affected by hypothermia, but not 40% dilution. TEG is affected by 40% dilution with Hextend, but not by hypothermia. PT and aPTT are significantly affected by both hypothermia and dilution. Recombinant FVIIa caused a greater change in thrombin generation at 34°C as compared to 37°C, and a greater change in PT at 40% dilution, suggesting that the effect of rFVIIa on coagulation is both temperature and dilution dependant.

Trauma, often accompanied by hemorrhage, is a leading cause of death worldwide, often leading to inflammation-related late complications that include sepsis and multiple organ failure. These secondary complications are a manifestation of the complexity of biological responses elicited by trauma/hemorrhage, responses that span most, if not all, cell types, tissues, and organ systems. This daunting complexity at the patient level is manifest by the near total dearth of available therapeutics, and we suggest that this dire condition is due in large part to the lack of a rational, systems-oriented framework for drug development, clinical trial design, in-hospital diagnostics, and post-hospital care. ⋯ We propose a rational framework for transitioning through the currently fragmented process from identification of biological networks that are potential therapeutic targets, through clinical trial design, to personalized diagnosis and care. Insights derived from systems and computational biology in trauma and sepsis include the centrality of Damage-Associated Molecular Pattern molecules as drivers of both beneficial and detrimental inflammation, along with a novel view of multiple organ dysfunction as a cascade of containment failures with distinct implications for therapy. Finally, we suggest how these insights might be best implemented to drive transformational change in the fields of trauma and sepsis.

Securing the airway is a crucial aspect during reconstructive surgeries of patients with extensive post-burn mentosternal scar contractures; however, the American Society of Anesthesiologists Difficult Airway Management Algorithm recommendation of initial direct laryngoscopy may not be appropriate for these complicated patients. Consequently, there is a significant risk for failure of intubation and airway emergency. ⋯ Many airway techniques have been effectively used in burn patients, but the role of awake blind or fiberoptic bronchoscopy, although well established in the non-burn population, has yet to be evaluated in burn patients. We report a case series of successful management of difficult airways with fiberoptic bronchoscopy in patients with varying degrees of post-burn head and neck scar contractures.
