Background: The trend in liver trauma management has progressively become increasingly conservative. However, a vast majority of literature focuses heavily on the management of blunt trauma. This study reviews the management of hepatic trauma at a major trauma center in a developing world setting, in order to compare blunt and penetrating liver trauma and to define current management algorithms and protocols. Methods: All patients who sustained liver trauma between 2012 to 2018 were identified in the Hybrid Electronic Medical Registry and extracted for further analysis. Results: A total of 808 patients with hepatic trauma were managed by our trauma center. There were 658 males and 150 females. The mean age was 30 years (standard deviation 13.3). A total of 68 patients died (8.2%) and a total of 290 (35%) patients required intensive care unit admission. The mean presenting shock index was 0.806 (standard deviation 0.67–1.0), the median Injury Severity Score was 18 (interquartile range 10–25) and the mean Revised Trauma Score was 12 (standard deviation 11–12). There were 367 penetrating and 441 blunt liver injuries. The age distribution was similar in both groups. There were significantly less females in the penetrating group. The shock index and the Injury Severity Score on presentation were significantly worse in the blunt group, respectively: 0.891 (standard deviation 0.31) versus 0.845 (standard deviation 0.69) (p < 0.001) and score 21 (interquartile range 13–27) versus 16 (interquartile range 9–20) (p < 0.01). The opposite applied to the Revised Trauma Score of 11.75 (standard deviation 0.74) versus 11.19 (standard deviation 1.3) (p < 0.001). There were significantly more associated intra-abdominal injuries in the penetrating group than the blunt group, in particular that of hollow organs, and 84% of patients with a penetrating injury underwent a laparotomy while only 33% of the blunt injuries underwent a laparotomy. The mortality rate was comparable between both groups. Conclusion: Hepatic trauma is still associated with a high morbidity rate, although there have been dramatic improvements in mortality rates over the last three decades. The mortality rates for blunt and penetrating liver trauma are now similar. Non-operative management is feasible for over two-thirds of blunt injuries and for just under 20% of penetrating injuries.

AbstractIntroductionThe Revised Trauma Score (RTS) has been proposed as an entry criterion to identify patients with mid-range survival probability for traumatic hemorrhagic shock studies.Hypothesis/ProblemDetermination of which of four RTS strata (1-3.99, 2-4.99, 1-4.99, and 2-5.99) identifies patients with predicted and actual mortality rates near 50% for use as an entry criterion in traumatic hemorrhagic shock clinical trials.MethodsExisting database analysis in which demographic and injury severity data from two prior international Diaspirin Cross-Linked Hemoglobin (DCLHb) clinical trials were used to identify an RTS range that could be an optimal entry criterion in order to find the population of trauma patients with mid-range predicted and actual mortality rates.ResultsOf 208 study patients, the mean age was 37 years, 65% sustained blunt trauma, 49% received DCLHb, and 57% came from the European Union study arm. The mean values were: ISS, 31 (SD = 18); RTS, 5.6 (SD = 1.8); and Glasgow Coma Scale (GCS), 10.4 (SD = 4.8). The mean TRISS-predicted mortality was 34% and the actual 28-day mortality was 35%. The initially proposed 1-3.99 RTS range (n = 41) had the highest predicted (79%) and actual (71%) mortality rates. The 2-5.99 RTS range (n = 79) had a 62% predicted and 53% actual mortality, and included 76% blunt trauma patients. Removal of GCS <5 patients from this RTS 2-5.99 subgroup caused a 48% further reduction in eligible patients, leaving 41 patients (20% of 208 total patients), 66% of whom sustained a blunt trauma injury. This subgroup had 54% predicted and 49% actual mortality rates. Receiver operator curve (ROC) analysis found the GCS to be as predictive of mortality as the RTS, both in the total patient population and in the RTS 2-5.99 subgroup.ConclusionThe use of an RTS 2-5.99 inclusion criterion range identifies a traumatic hemorrhagic shock patient subgroup with predicted and actual mortality that approach the desired 50% rate. The exclusion of GCS <5 from this RTS 2-5.99 subgroup patients yields a smaller, more uniform patient subgroup whose mortality is more likely related to hemorrhagic shock than traumatic brain injury. Future studies should examine whether the RTS or other physiologic criteria such as the GCS score are most useful as traumatic hemorrhagic shock study entry criteria.Sloan EP, Koenigsberg M, Clark JM, Desai A.

RESUMO Objetivo identificar estudos que realizaram ajustes na equação do Trauma and InjurySeverity Score (TRISS) e compararam a capacidade discriminatória da equação modificada com a original. Método Revisão integrativa de pesquisas publicadas entre 1990 e 2014 nas bases de dados LILACS, MEDLINE, PubMed e SciELO utilizando-se a palavra TRISS. Resultados foram incluídos 32 estudos na revisão. Dos 67 ajustes de equações do TRISS identificados, 35 (52,2%) resultaram em melhora na acurácia do índice para predizer a probabilidade de sobrevida de vítimas de trauma. Ajustes dos coeficientes do TRISS à população de estudo foram frequentes, mas nem sempre melhoraram a capacidade preditiva dos modelos analisados. A substituição de variáveis fisiológicas do Revised Trauma Score (RTS) e modificações do Injury Severity Score (ISS) na equação original tiveram desempenho variado. A mudança na forma de inclusão da idade na equação, assim como a inserção do gênero, comorbidades e mecanismo do trauma apresentaram tendência de melhora do desempenho do TRISS. Conclusão Diferentes propostas de ajustes no TRISS foram identificadas nesta revisão e indicaram, principalmente, fragilidades do RTS no modelo original e necessidade de alteração da forma de inclusão da idade na equação para melhora da capacidade preditiva do índice.

The Functional Independence Measure (FIM) is used by rehabilitation professionals to access disability. The FIM score combines both motor and cognitive parameters to assess a patient's level of required assistance in performing activities of daily living (ADL). The geriatric trauma patient is becoming an increasingly important cohort for trauma services. FIM has been shown to predict discharge outcomes and those at high risk for falls. We hypothesized pretrauma FIM scores may predict survival in the geriatric trauma population. This was a retrospective study of patients 65 years and older that were admitted to our Level I trauma center from July 1, 2006 to July 1, 2012. A total 941 patients underwent stepwise regression to identify those factors predicting survival. Age, Injury Severity Score, revised trauma score, body mass index, and pretrauma FIM scores (12-point scale) were studied. The primary outcome was survival. Statistical significance reached at P value <0.05. Multiple logistic regression analysis was then performed. A total of 1315 patients were identified and complete data were available on 941 patients. Mean age was 78 (SD ± 8.2), mean Injury Severity Score was 13(SD ± 8.7), and mean body mass index was 26. Overall mortality was 11 per cent. The odds ratio of survival was 3.532 (95% confidence interval = 2.191–5.718) times greater for every 1-point increase in the preadmission FIM expression score. Glasgow Coma Scale, revised trauma score, gender, and pretrauma FIM expression scores were predictive of survival in the geriatric trauma patient. Pretrauma FIM expression can be used to predict survival in the elderly trauma victim. Further study is needed to establish the role of FIM as part of trauma scoring systems.

Introduction:Triaging plays an important role in providing suitable care to the largest number of casualties in a disaster setting. We developed the Pediatric Physiological and Anatomical Triage score (PPATS) as a new secondary triage method.Aim:This study was performed to validate the accuracy of the PPATS in pediatric patients with burn injuries.Methods:A retrospective review of pediatric patients with burn injuries younger than 15 years old registered in the Japan Trauma Databank from 2004 to 2016 was conducted. The PPATS, which was assigned scores from 0 to 22, was calculated based on vital signs, anatomical abnormalities, and need for life-saving intervention. The PPATS categorized the patients by their priority and defined the intensive care unit (ICU)-indicated patients as those with PPARSs more than 6. This study compared the accuracy of prediction of ICU-indicated patients between the PPATS and Triage Revised Trauma Score (TRTS).Results:Among 87 pediatric patients, 62 (71%) were admitted to the ICU. The median age was 3 years (interquartile range: 1 to 9 years old). The sensitivity and specificity of the PPATS were 74% and 36%, respectively. The area under the receiver-operating characteristic curve was not different between the PPTAS [0.51 (95% confidence interval: -0.51–1.48) and the TRTS [0.51 (-1.17–1.62), p=0.57]. Regression analysis showed a significant association between the PPATS and the Injury Severity Score (ISS) (r2=0.39, p<0.01). On the other hand, there is no association between the TRTS and the ISS (r2=0.00, p=0.79).Discussion:The accuracy of the PPATS was not superior to that of current secondary-triage methods. However, the PPATS had the advantage of objectively determining the triage priority ranking based on the severity of the pediatric patients with burn injuries.

Car surfing is a dangerous new pastime for American youth. Car surfing is an activity that is defined as standing (or lying) on a vehicle while it is being driven. This activity frequently results in severe injuries that often require significant surgical intervention. Despite its destructive nature, however, there are many Internet sites that encourage this behavior and view it as amusing. As a result, car surfing is becoming increasingly popular. We conducted a retrospective chart review of all patients injured as a result of car surfing over the last 4 years at our Urban Level II trauma center. Data collected included Injury Severity Score (ISS), Revised Trauma Score (RTS), age, gender, injury pattern, surgical intervention, and length of stay. Eight car surfers were identified. The average age was 17. The average Revised Trauma Score was 6.8 with an average Injury Severity Score of 16.9. Five patients were admitted to the intensive care unit. Four of these five patients needed to be intubated for ventilatory support. Five of the eight patients had significant intracranial injuries. Two patients had epidural hematomas that required evacuation. Two other patients had subdural hematomas that were treated nonoperatively, and one patient had a subarachnoid hemorrhage that was also treated nonoperatively. Four of the eight patients required surgical intervention. There were no deaths in this study. Car surfing leads to severe injuries that can result in significant morbidity. American youth have access to Internet sites that project this activity as an acceptable behavior. Five of our eight patients had a significant intra-cranial injury. Trauma surgeons need to be more aware of this injury phenomenon.

The purpose of this study was to describe the characteristics of this unique patient population, their clinical presentations, and outcomes. The Los Angeles County and University of Southern California Medical Center Trauma Registry was used to retrospectively identify patients who sustained perineal injuries. Information included gender, age, vital signs, trauma scores, mechanisms of injury, studies performed, surgeries performed, and outcomes. Pediatric patients and injuries related to obstetric trauma were not included. Sixty-nine patients were identified between February 1, 1992 and October 31, 2005. One patient died on arrival; 85 per cent (58 of 68) were males, mean age was 30 ± 12 years, and there was a penetrating mechanism in 56 per cent. Vital signs on admission were systolic blood pressure 119 ± 33 mmHg, heart rate 94 ± 27 beats/minute, and respiratory rate 20 ± 6 breaths/min. Glasgow Coma Scale (GCS) was 13 ± 3, Revised Trauma Score (RTS) was 7.2 ± 1.5, and Injury Severity Score (ISS) was 11 ± 12. CT scan was obtained for 23 (33%) patients. Lower extremity fractures were 35 per cent and pelvic fractures 32 per cent. The most common surgery was debridement and drainage, diversion with colostomy in five patients (7%). Overall mortality was 10 per cent. Mortality group mean scores were: GCS, 6; RTS, 5.74; and ISS, 34. The survival group mean scores were: GCS, 14; RTS, 7.7; and ISS, 8. There was a statistically significant association between mortality and GCS, RTS, and ISS scores ( P < 0.001). Most patients with perineal injuries (93%) can be managed without colostomy. Associated injuries are not uncommon, particularly bony fractures. Mortality is mostly the result of exsanguination related to associated injuries.

OBJETIVO: Identificar fatores prognósticos relacionados com a falha do tratamento não-operatório (TNO) de lesões esplênicas no trauma abdominal fechado. MÉTODOS: Análise prospectiva de 56 pacientes adultos submetidos à TNO e divididos em um grupo de sucesso e outro de falha, que foi definida como necessidade de laparotomia por qualquer indicação. As lesões foram diagnosticadas por tomografia computadorizada e classificadas de acordo com os critérios da AAST (American Association for Surgery of Trauma). Os parâmetros estudados foram: na admissão - pressão arterial sistólica, frequências cardíaca e respiratória, nível de consciência (Escala de Glasgow) e RTS (Revised Trauma Score); durante a hospitalização - presença de lesões associadas, transfusão sanguínea e parâmetros hematológicos, tempo de internação e ISS (Injury Severity Score). RESULTADOS: As falhas do TNO (19,6%) foram devidas à dor abdominal (45,4%), instabilidade hemodinâmica (36,4%), queda do volume globular associada a hematoma esplênico (9,1%) e abscesso esplênico (9,1%). Não foram observadas diferenças entre os grupos de sucesso e de falha nos dados na admissão. A taxa de falha de acordo com o grau da lesão esplênica foi 0% nos graus I e II agrupados; 17,5% nos graus III e IV agrupados e 80% no grau V (p = 0,0008). O uso de hemoderivados foi maior e mais frequente no grupo de falha (p=0,05). As relação do ISS (Injury Severity Score) com as taxas de falha foram 0% nos pacientes com ISS = 8; 15,9% nos com ISS entre 9 e 25, e 50% nos com ISS = 26 (p = 0,05). Não houve mortalidade e nem lesões de vísceras ocas despercebidas. CONCLUSÃO: O Injury Severity Score e grau da lesão esplênica relacionaram-se com a falha do tratamento não-operatório.

OBJETIVO: Contesta-se a aplicação indiscriminada da toracotomia de reanimação (TR) no trauma. Este estudo objetiva reavaliar as indicações de TR na nossa instituição. MÉTODO: Estudo retrospectivo envolvendo 126 pacientes submetidos à TR entre janeiro de 1995 e dezembro de 2004. Definiram-se quatro grupos considerando os sinais vitais dos pacientes na admissão: morto ao chegar, fatal, agônico e choque profundo. O protocolo incluiu dados como mecanismo de trauma, sinais vitais, Escore de Trauma Revisado (Revised Trauma Score ou RTS), locais de lesão (identificados durante cirurgia ou autópsia), Índice de Gravidade da Lesão (Injury Severity Score ou ISS) e sobrevida. RESULTADOS: Setenta e dois (57,2%) pacientes apresentavam ferimento por projétil de arma de fogo, 11 (8,7%) ferimento por arma branca e 43 (34,1%) por trauma fechado. Nenhum dos sessenta pacientes (47,6%) dos grupos fatal e morto ao chegar sobreviveu, mas 13 (39,4%) dos pacientes fatais foram encaminhados ao centro cirúrgico (CC) para tratamento definitivo. Dos 66 pacientes dos grupos agônico e choque profundo, 44 (66,7%) foram submetidos a TR no prontosocorro (PS) e 31 (70,5%) destes foram transferidos até o CC. Nos 22 restantes, a parada cardiorrespiratória ocorreu já no CC, onde foi feita a TR. Dois pacientes do grupo choque profundo sobreviveram (1,6% do total) e receberam alta com função cerebral normal. O ISS médio foi 33, sendo exsangüinação a causa mais freqüente de óbito. CONCLUSÕES: Resultados ruins enfatizam a necessidade de uma abordagem mais seletiva para aplicar a TR. Um algoritmo baseado no mecanismo de trauma e nos sinais vitais na admissão é proposto para otimizar as indicações de TR.
