Multicenter Study Clinical Trial
A predictive model of early mortality in trauma patients.
Rapid thrombelastography (rTEG) is a real-time whole-blood viscoelastic coagulation assay. We hypothesized that admission rTEG and clinical data are independent predictors of trauma-related mortality. ⋯ This 5-variable model provides a rapid prediction of 24-hour mortality. The inclusion of rTEG Ly30 demonstrates the association of fibrinolysis with outcome and may support the early use of antifibrinolytic therapies.

Newer studies have hypothesised about a coagulopathy that occurs early after trauma, early trauma induced coagulopathy, ETIC, and is defined by an elevated admission prothrombin time (PT). Also, referred to by some authors as acute traumatic coagulopathy, it has been most often studied in cohorts of severely injured or hypotensive patients. However, we wanted to prospectively investigate ETIC in a large all-comers cohort to confirm its prevalence across the entire spectrum of injury, to evaluate its risk pattern and to determine a possible relationship to reduced survival. ⋯ ETIC is an early, primary post-injury coagulopathy that occurs in 16.3% of admitted trauma patients. It is associated with an increase in mortality, even when controlling for crystalloids, vital signs, injury severity and head injury. It can also be found in approximately 11% of mildly injured patients (patients without physiological derangement or blood product administration). Therefore, further elucidation of ETIC is strategic to impacting trauma patient outcome.

Blast injury and the human skeleton: an important emerging aspect of conflict-related trauma.
Recent decades have seen an accelerating trend in warfare whereby a growing proportion of conflict-related deaths have been caused by explosions. Analysis of blast injury features little in anthropological literature. ⋯ Potential indicators of blast trauma include blowout fractures in sinus cavities from blast overpressure, transverse mandibular fractures, and visceral surface rib fractures. Ability to recognize blast trauma and distinguish it in the skeleton is of importance in investigations and judicial proceedings relating to war crimes, terrorism, and human rights violations and likely to become increasingly crucial to forensic anthropology knowledge.

Pediatric Liver Lacerations and Intensive Care: Evaluation of ICU Triage Strategies.
To compare PICU admission criteria following blunt traumatic liver laceration based on CT grade and/or physiologic instability with actual practice to improve efficiency of ICU admission. ⋯ Children with isolated abdominal injury and no physiologic instability can generally be treated without ICU admission. Adding grade more than or equal to 4 to usual ICU admission criteria resulted in excessive admission of stable patients.

A variety of point-of-care monitors for the measurement of hematocrit, hemoglobin, blood gas with electrolytes, and lactate can be used also in the prehospital setting for optimizing and individualizing trauma resuscitation. Point-of-care coagulation testing with activated prothrombin test, prothrombin test, and activated coagulation/clotting time tests is available for prehospital use. Although robust, battery driven, and easy to handle, many devices lack documentation for use in prehospital care. ⋯ Sonoclot and Rheorox are two small viscoelastic instruments with one-channel options, but with less documentation. The point-of-care market for coagulation tests is quickly expanding, and new devices are introduced all the time. Still they should be better adopted to prehospital conditions, small, robust, battery charged, and rapid and use small sample volumes and whole blood.
