Major trauma is a leading cause of mortality and serious morbidity. Recent approaches to life-threatening traumatic haemorrhage have emphasized the importance of early blood product transfusion. We have implemented a pre-hospital transfusion request policy where a pre-hospital physician can request the presence of a major transfusion pack on arrival at the destination trauma centre. ⋯ The use of simple pre-hospital criteria allowed physicians to successfully identify trauma patients with severe injury and a requirement for blood product transfusion. This allowed blood products to be ready on the patient's arrival in a major trauma centre with the potential for earlier transfusion.

Pulmonary contusion is a major risk factor of acute respiratory distress syndrome (ARDS) in trauma patients. As this complication may appear after a free interval of 24-48 h, detection of patients at risk is essential. The main objective of this study was to assess the performance of the Thoracic Trauma Severity (TTS) score upon admission in predicting delayed ARDS in blunt trauma patients with pulmonary contusion. ⋯ An extreme TTS score on admission accurately predicts the occurrence of delayed ARDS in blunt thoracic trauma patients affected by pulmonary contusion. This simple score could guide early decision making and management for a non-negligible proportion of this specific population.

Motor vehicle intrusion (MVI) is one of the field triage criteria recommended by the American College of Surgeons Committee of Trauma (ACS-COT) and Centers for Disease Control and Prevention (CDC). However, the evidence supporting its validity is scarce. The purpose of this study was to evaluate the validity of this criterion and assess its impact on overtriage or undertriage. ⋯ The MVI itself did not appear to be a strong indicator for the use of trauma center resources and is associated with excessive overtriage. However, age >65 years, systolic blood pressure <110 mmHg, and heart rate >100/min were significant predictors for the need of trauma center resources. The MVI criterion should be refined for better utilization of trauma center resources.

Comparative Study
Predicting in-hospital mortality of traffic victims: A comparison between AIS-and ICD-9-CM-related injury severity scales when only ICD-9-CM is reported.
Injury severity scores are important in the context of developing European and national goals on traffic safety, health-care benchmarking and improving patient communication. Various severity scores are available and are mostly based on Abbreviated Injury Scale (AIS) or International Classification of Diseases (ICD). The aim of this paper is to compare the predictive value for in-hospital mortality between the various severity scores if only International Classification of Diseases, 9th revision, Clinical Modification ICD-9-CM is reported. ⋯ When only ICD-9-CM codes are reported, ICD-9-CM-based severity scores perform better than severity scores based on the conversion to AIS.

Elderly people, due to neurological conditions and muscular atrophy, present a greater propensity to falls and thus are very susceptible to hip fractures. Other variables, such as osteoporosis, may also be related to the etiopathogenesis of hip fractures, although osteoporosis is in fact a concurrent disease, and merely a coadjutant cause. Nonetheless, osteoporosis can make fracture patterns more severe and interfere with osteosynthesis. ⋯ Furthermore, increased crystal size, increased cortical porosity, reduced osteocyte lacunar density and an increased Ca/P ratio associated with higher concentrations of Ca and P were described in hip fracture patients compared to control patients. Osteocalcin/collagen type 1 expression ratio and enzymatic cross-link content in high-density bone was found to be significantly lower in hip fractures compared to controls. In conclusion, further research in bone mineral density and associated parameters are of interest to deepen the understanding of osteoporotic hip fractures.
