Surviving Nonsurvivable Injuries: Patients Who Elude the ‘Lethal’ Abbreviated Injury Scale (AIS) Score of Six

Motor Vehicle Crashes (MVCs) are a public health problem in the United States. In 2009, 33,808 Americans were killed in a MVC and 2.22 million more were injured.4 Pulmonary contusion (PC) is a common injury following MVC with over 38% of the Abbreviated Injury Scale (AIS) 3+ thoracic injuries identified as some form of PC in a recent National Automotive Sampling System (NASS) study.5 Miller et al. correlated the percent injured lung to the possibility of developing Acute Respiratory Distress Syndrome (ARDS). The results indicated that if 20% of the lung was injured, the incidence of ARDS sharply increased with seventy-eight percent of those patients developing ARDS.2 The significance of these findings is that the volumetric measurement of PC can predict possible clinical outcomes.

Abbreviated Injury Scale

OBJETIVO: identificar entre as características das vítimas de trauma crânio-encefálico contuso (idade, sexo, escolaridade, antecedentes, tempo de internação, complicações pós-traumáticas e indicadores da gravidade do trauma e lesão craniana) fatores de risco para prognóstico desfavorável. MÉTODOS: análise de 63 vítimas, com idade entre 12 e 65 anos, em seguimento ambulatorial em centro para atendimento de trauma, entre 6 meses e 3 anos após evento traumático. Utilizando-se a regressão logística múltipla foi construído um modelo para condição funcional. RESULTADOS: indivíduos que alcançaram pontuação 5 no máximo Abbreviated Injury Scale da região cabeça tiveram 4,89 vezes mais chance de dependência quando comparados com os que apresentaram escore menor. Vítimas internadas durante 12 dias ou mais mostraram 5,76 vezes mais chance para se tornarem dependentes em relação às demais. CONCLUSÃO: os fatores de risco para dependência foram o máximo Abbreviated Injury Scale da região cabeça e o tempo de internação.

Abstract Background To fully understand the injury mechanisms during an underbody blast (UBB) event with military vehicles and develop new testing standards specific to military vehicles, one must understand the injuries sustained by the occupants. Methods Injury data from Service Members (SM) involved in UBB theater events that occurred from 2010 to 2014 were analyzed. Analysis included the investigation of prominent skeletal and visceral torso injuries. Results were categorized by killed-in-action (n = 132 SM) and wounded-in-action (n = 1,887 SM). Results Over 90% (553/606 SM) of casualties in UBB events with Abbreviated Injury Scale (AIS) 2+ injury sustained at least one skeletal fracture, when excluding concussion. The most frequent skeletal injuries from UBB were foot fractures (13% of injuries) for wounded-in-action and tibia/fibula fractures (10% of injuries) for killed-in-action. Only 1% (11/1037 SM) of all casualties with AIS 2+ injuries had visceral torso injuries without also sustaining skeletal fractures. In these few casualties, the coded injuries were likely due to trauma from a loading path other than direct UBB loading. Conclusion Skeletal fractures are the most frequent AIS 2+ injury resulting from UBB events. Visceral torso injuries are infrequent in individuals that survive and they generally occur in conjunction with skeletal injuries.

Injured Patients

Introductio: Although management of severely injured patients in the Trauma Resuscitation Unit (TRU) follows evidence-based guidelines, algorithms for treatment of the slightly injured are limited. Methods: All trauma patients in a period of eight months in a Level I trauma center were followed. Retrospective analysis was performed only in patients ≥18 years with primary TRU admission, Abbreviated Injury Scale (AIS) ≤ 1, Maximum Abbreviated Injury Scale (MAIS) ≤ 1 and Injury Severity Score (ISS) ≤3 after treatment completion and ≥24 h monitoring in the units. Cochran’s Q-test was used for the statistical evaluation of AIS and ISS changes in units. Results: One hundred and twelve patients were enrolled in the study. Twenty-one patients (18.75%) reported new complaints after treatment completion in the TRU. AIS rose from the Intermediate Care Unit (IMC) to Normal Care Unit (NCU) 6.2% and ISS 6.9%. MAIS did not increase >2, and no intervention was necessary for any patient. No correlation was found between computed tomography (CT) diagnostics in TRU and AIS change. Conclusions: The data suggest that AIS, MAIS and ISS did not increase significantly in patients without a severe injury during inpatient treatment, regardless of the type of CT diagnostics performed in the TRU, suggesting that monitoring of these patients may be unnecessary.

Trauma Severity

Objetivo: Comparar a gravidade das lesões e do trauma mensurada pelas versões da Abbreviated Injury Scale 1998 e 2005 e verificar a mortalidade nos escores Injury Severity Score e New Injury Severity Score nas duas versões.Método: Estudo transversal e retrospectivo analisou lesões de pacientes de trauma, de três hospitais universitários do município de São Paulo, Brasil. Cada lesão foi codificada com Abbreviated Injury Scale 1998 e 2005. Os testes estatísticos aplicados foram Wilcoxon, McNemar-Bowker, Kappa e teste Z.Resultados: A comparação das duas versões resultou em discordância significante de escores em algumas regiões corpóreas. Com a versão 2005 os níveis de gravidade da lesão e do trauma foram significantemente reduzidos e a mortalidade foi mais elevada em escores mais baixos. Conclusão: Houve redução da gravidade da lesão e do trauma e alteração no percentual de mortalidade com o uso da Abbreviated Injury Scale 2005.
