the trauma registry provides a clear picture of the points to be improved in trauma patient care, however, there are specific peculiarities for implementing this tool in the Brazilian milieu.
Objective: to identify victims of blunt abdominal trauma in which intra-abdominal injuries can be excluded by clinical criteria and by complete abdominal ultrasonography. Methods: retrospective analysis of victims of blunt trauma in which the following clinical variables were analyzed: hemodynamic stability, normal neurologic exam at admission, normal physical exam of the chest at admission, normal abdomen and pelvis physical exam at admission and absence of distracting lesions (Abbreviated Injury Scale >2 at skull, thorax and/or extremities). The ultrasound results were then studied in the group of patients with all clinical variables evaluated. Results: we studied 5536 victims of blunt trauma. Intra-abdominal lesions with AIS>1 were identified in 144 (2.6%); in patients with hemodynamic stability they were present in 86 (2%); in those with hemodynamic stability and normal neurological exam at admission in 50 (1.8%); in patients with hemodynamic stability and normal neurological and chest physical exam at admission, in 39 (1.5%); in those with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, in 12 (0.5%); in patients with hemodynamic stability, normal neurological, chest, abdominal and pelvic physical exam at admission, and absence of distracting lesions, only two (0.1%) had intra-abdominal lesions. Among those with all clinical variables, 693 had normal total abdominal ultrasound, and, within this group, there were no identified intra-abdominal lesions. Conclusion: when all clinical criteria and total abdominal ultrasound are associated, it is possible to identify a group of victims of blunt trauma with low chance of significant intra-abdominal lesions.
Objective: to review the clinical assessment of head injuries in motorcyclists involved in traffic accidents. Method: prospective observational study, including adult motorcyclists involved in traffic accidents in a period of 12 months. Patients sustaining signs of intoxication were excluded. A modification of the Canadian Head CT Rules was used to indicate computed tomography (CT). Patients not undergoing CT were followed by phone calls for three months. Collected variables were compared between the group sustaining head injuries and the others. We used chi-square, Fisher, and Student’s t for statistical analysis, considering p<0.05 as significant. Results: we included 208 patients, 99.0% were wearing helmets. Seventeen sustained signs of intoxication and were excluded. Ninety (47.1%) underwent CT and 12 (6.3%) sustained head injuries. Head injuries were significantly associated with Glasgow Coma Scale<15 (52.3% vs. 2.8% - p<0,001) and a positive physical exam (17.1% vs. zero - p<0,05). Four (2.1%) patients with intracranial mass lesions needed surgical interventions. None helmet-wearing patients admitted with GCS=15 and normal physical examination sustained head injuries. Conclusion: Head CT is not necessary for helmet-wearing motorcyclists admitted with GCS=15 and normal physical examination.
RESUMO Objetivo: análise crítica da investigação diagnóstica de lesões em segmento cefálico de motociclistas vítimas de acidentes de tráfego. Método: estudo observacional prospectivo incluindo motociclistas adultos vítimas de trauma, sem intoxicação exógena, em um período de 12 meses. A tomografia de crânio (TC) foi indicada de acordo com uma modificação dos “critérios canadenses”. Os pacientes que não foram submetidos a TC de crânio tiveram acompanhamento telefônico por três meses. A presença de lesões foi correlacionada com as varáveis coletadas através dos testes Qui-quadrado, t de Student ou Fisher, considerando p<0,05 como significativo. Resultados: dos 208 inicialmente incluídos, 206 (99,0%) estavam usando capacete. Dezessete estavam com sinais de intoxicação exógena e foram excluídos, restando 191 para análise. Noventa pacientes (47,1%) realizaram TC e 12 (6,3%) apresentaram lesões craniencefálicas, que se associaram significativamente a Escala de Coma de Glasgow (ECG) <15 (52,3% vs. 2,8% - p<0,001) e alterações ao exame físico da região cefálica/neurológico (17,1% vs. zero - p<0,05). Quatro pacientes (2,1%) precisaram tratamento cirúrgico de lesões intracranianas. Nenhum dos pacientes admitidos com ECG 15, em uso de capacete e sem alterações no exame físico apresentou TC alterada. Conclusões: para pacientes admitidos com ECG 15, que utilizavam o capacete no acidente e não apresentavam quaisquer alterações no exame físico, a realização da TC de crânio não trouxe mudanças no atendimento ao paciente. .
