Introduction: This study assesses the incidence of missed pelvic injuries in the pre-hospital setting. Methods: All blunt trauma patients (ISS ≥ 9) with pre-hospital suspicion of and/or radiologically proven pelvic fracture documented in the TraumaRegister DGU (TR-DGU) of the German Trauma Society DGU (2002-2011) were identified and retrospectively analyzed. Patients with a missed pelvic injury in the pre-hospital period were compared with those who were correctly identified. Results: Of the 11,062 patients included, 7201 patients (65.1 %) had a pelvic fracture diagnosed on hospital admission. In 44.1 % ( n = 3178) of the patients with confirmed pelvic fracture, no pelvic injury was suspected pre-clinically (overall sensitivity of the pre-hospital pelvic examination: 55.9 %). For type B and C pelvic fractures, 40.5 % and 32.3 %, respectively, were not suspected in the pre-hospital environment. Patients with a not-suspected pelvic injury were significantly more likely to have been involved in a motor vehicle accident, to have a GCS ≤ 8, to be intubated at the scene and to have an ISS of ≥25 (all p < 0.05). Independent risk factors for missing a pelvic injury in the pre-hospital setting were an AIS head ≥3, a GCS ≤ 8 and age above 60 years. The presence of hypotension (SBP ≤ 90 mmHg) as well as a high overall injury severity (ISS ≥ 25) decreased the risk of missing a pelvic injury. Conclusion: A significant proportion of severe pelvic fractures type B and C were not suspected in the pre-hospital setting. Therefore, in severely injured blunt trauma patients, a mechanical pelvic stabilization in the pre-hospital environment, irrespective of the findings of the physical examination of the pelvis, should be considered.

Background: Damage control (DC) strategy has significantly contributed to mortality reduction in massively bleeding and critically injured trauma victims. However, there is a lack of literature validating the effectiveness of this approach in the elderly population. Methods: The trauma registry of a Level I trauma center was utilized to identify all severely injured patients [Injury Severity Score (ISS) ≥16] from January 1996 to December 2007 who underwent initial DC procedures. Patients with a head Abbreviated Injury Scale (AIS) ≥3 were excluded from the analysis. Demographics, clinical and physiological parameters, and in-hospital outcome measures were compared between elderly (≥55 years) and younger (<55 years) patient cohorts subjected to DC procedures. Results: Overall, 158 patients met the inclusion criteria. Among them, 34 patients (21.5%) were aged ≥55 years (range 55-85 years) and 124 patients (78.5%) were <55 years old (range 16-54 years). The overall in-hospital mortality rate was 10.1% ( n = 16) with a significantly higher mortality rate for elderly patients than for younger patients: 29.4% vs. 4.8%; adjusted P = 0.001; adjusted odds ratio (OR) with 95% confidence interval (CI) 7.09 (2.30-21.74). When stratified by DC subgroups, the case-fatality rate was significantly higher for the elderly patients who underwent extremity DC procedures [19.2% vs. 3.2%; adjusted P = 0.032; adjusted OR with 95% CI 5.95 (1.16-30.30)] and DC laparotomy [55.6% vs. 7.1%; P = 0.005; OR and 95% CI 16.25 (2.32-114.06)]. Both cohorts required massive transfusion during the initial 24 h of admission (18.9 ± 2.9 vs. 15.1 ± 1.6 units of packed red blood cells; P = 0.290). Nevertheless, there were no statistically significant differences between the two groups regarding hospital and surgical intensive care unit lengths of stay or major in-hospital complications. Conclusions: The mortality rate for elderly trauma patients undergoing DC is excessive at 29%. Despite the significant burden of injury and the massive transfusion requirement, most of the elderly patients subjected to DC survived and experienced in-hospital morbidity measures comparable to those of the younger patients. Our results provide further support for damage control intervention in severely injured elderly patients. [ABSTRACT FROM AUTHOR]
