Fatores prognósticos relacionados à falha do tratamento não-operatório de lesões esplênicas no trauma abdominal fechado

OBJECTIVE: Identify prognostic factors related to treatment failure of blunt splenic injuries managed by non surgical treatment (NST). METHODS: Fifty six adult patients submitted to NST were prospectively studied. The injuries were diagnosed by computed axial tomography scan and classified according to AAST (American Association for Surgery of Trauma) criteria. Patients were divided in success and failure groups. NST failure was defined as the need for laparotomy for any reason. RESULTS: NST failures (19.6%) were due to: abdominal pain (45.4%), hemodinamic instability (36.4%), splenic haematoma associated to a fall in hematocrit (9.1%) and splenic abscess (9.1%). There were no failures in grade I and II of the splenic injuries; failure rate was 17.5% in grade III and IV injuries grouped, and 80% in grade V injuries (p = 0,0008). In the success group, 31.3% patients received red cell transfusions, versus 63.6% patients in the failure group (p = 0,05). Failure rate in patients with ISS = 8 was zero; 15.9% in patients with ISS 9 to 25; and 50% in patients with ISS = 26 (p = 0,05). There were no deaths or missed bowel injuries. CONCLUSION: ISS and splenic injury grade were related to failure of NST.

Perfil epidemiológico de acidentes com material biológico entre estudantes de medicina em um pronto-socorro cirúrgico

OBJECTIVE: To evaluate the accidents with biological material among medical students interning in a trauma emergency room and identify key related situations, attributed causes and prevention. METHODS: we conducted a study with a quantitative approach. Data were collected through a questionnaire applied via internet, with closed, multiple-choice questions regarding accidents with biological material. The sample comprised 100 students. RESULTS: thirty-two had accidents with biological material. Higher-risk activities were local anesthesia (39.47%), suture (18.42%) and needle recapping (15.79%). The main routes of exposure to biological material were the eyes or mucosa, with 34%, and syringe needle puncture, with 45%. After contamination, only 52% reported the accident to the responsible department. CONCLUSION: The main causes of accidents and routes of exposure found may be attributed to several factors, such as lack of training and failure to use personal protective equipment. Educational and preventive actions are extremely important to reduce the incidence of accidents with biological materials and improve the conduct of post-exposure. It is important to understand the main causes attributed and situations related, so as general and effective measures can be applied.

Mesenteric thrombosis in patient victim of blunt abdominal trauma with fatal outcome

INTRODUCAO: Trombose mesenterica, relacionada a trauma e entidade incomum, com pobre prognostico quando seguida de estados de baixo fluxo e choque hipovolemico. Geralmente apresenta-se com quadro de dificil diagnostico, cuja mortalidade e elevada a despeito de tratamento adequado. RELATO DO CASO: Paciente submetido a trauma, apos admissao hospitalar e atendimento inicial, exames radiologicos demonstraram fratura de costela e umero. Tomografia computadorizada evidenciou distensao aerea em intestino delgado associada a estase gastrica e hidropneumotorax. O paciente evoluiu com hipotensao durante o periodo de observacao clinica e parada cardiorrespiratoria que respondeu a reanimacao. Levado para operacao para controle de danos, encontrou-se extensa necrose de colon ascendente. Realizou-se hemicolectomia direita com ileotransversostomia. Levado a unidade de terapia intensiva, evoluiu com oliguria, miose, convulsao e atividade eletrica sem pulso, falecendo tres dias apos dar entrada no hospital. CONCLUSAO: Embora incomum, isquemia mesenterica com trombose venosa pode ser secundaria a hipotensao sistemica, com desfecho fatal.

Risk factors for mortality in blunt abdominal trauma with surgical approach

OBJECTIVE identify risk factors for mortality in patients who underwent laparotomy after blunt abdominal trauma. METHODS retrospective study, case-control, which were reviewed medical records of blunt trauma victims patients undergoing laparotomy, from March 2013 to January 2015, and compared the result of the deaths group with the group healed. RESULTS of 86 patients, 63% were healed, 36% died, and one patient was excluded from the study. Both groups had similar epidemiology and trauma mechanism, predominantly young adults males, automobilistic accident. Most cases that evolved to death had hemodynamic instability as laparotomy indication - 61% against 38% in the other group (p=0.02). The presence of solid organ injury was larger in the group of deaths - 80% versus 48% (p=0.001) and 61% of them had other associated abdominal injury compared to 25% in the other group (p=0.01). Of the patients who died 96% had other serious injuries associated (p=0.0003). Patients requiring damage control surgery had a higher mortality rate (p=0.0099). Only one of 18 patients with isolated hollow organ lesion evolved to death (p=0.0001). The mean injury score of TRISS of cured (91.70%) was significantly higher than that of deaths (46.3%) (p=0.002). CONCLUSION the risk factors for mortality were hemodynamic instability as an indication for laparotomy, presence of solid organ injury, multiple intra-abdominal injuries, need for damage control surgery, serious injury association and low index of trauma score.

Preventive peer-educational activities: what can medical students do to potentially save lives?

Traffic injuries are amongst the main causes of death worldwide. Even with the advances in technology, there are still 50% of deaths that cannot be reduced by medical care improvement. These important injuries can though be reduced by prevention of trauma. One of the best ways to address this issue is through incorporating preventive measures to the daily routine of schools. It is the aim of this study to assess children’s perception on traumatic events and to introduce a cost-effective peer-education preventive action.

Orientações de alta: cartões padronizados ajudam na compreensão dos pacientes do pronto socorro?

OBJECTIVE: To determine whether the addition of discharge standard illustrated cards improves understanding of patients in the emergency room. METHODS: We conducted a prospective, randomized, interventional study with 228 patients discharged from the emergency department. All patients were interviewed and tested for the level of understanding of discharge instructions. Some of them received the intervention, with the standard cards, and another did not, constituting the control group. RESULTS: The average of followed discharge guidelines of the group that received the cards was higher than the control group, with statistical significance (p=0.009). When segregated by age, the group between 16 and 35 years of both sexes had the best average of followed guidelines, statistically, than the average of the control group (p=0.01). The difference between the mean orientations between the control group and the card for patients undergoing procedures was statistically significant (p=0.02); as for the stratification according to the number of procedures, the significance increases when that is equal to 1 (p=0.001) and decreased the more procedures were carried out. CONCLUSION: The introduction of discharge standard orientation cards was associated with improvement in the understanding of patients. Without replacing the verbal directions, which establishes dialogue and doctor-patient bonding, cards appear as auxiliary elements, facilitating understanding and care guidelines.

Mesenteric thrombosis in patient victim of blunt abdominal trauma

INTRODUCTION: Mesenteric thrombosis related to trauma is an uncommon entity and has poor prognosis when associated to low perfusion and hemorrhagic shock. Usually presents a challenging diagnosis and high mortality rates, despite appropriate treatment. OBJECTIVE: To relate a case of a car accident and blunt abdominal trauma with terminal ileum and right colon necrosis. CASE REPORT: After initial procedures, complementary exams showed ribs and humerus fractures. Computerized tomography evidenced aerial distension in small bowel, gastric stasis and hidro-pneumothorax. Hypotension was observed during clinical observation followed by cardiopulmonary arrest, responding to reanimation. At surgery, it was found extensive necrosis of right colon and terminal ileum, and an ileum-transversostomy was performed with primary anastomosis. During the staying in intensive care unit, oliguria, miosis, convulsion and pulseless electric activity happened with death in three days after hospital admission. CONCLUSION: Although uncommon, mesenteric ischemia with venous thrombosis might be secondary to blunt abdominal trauma and must be considered in a bad abdominal evolution.

Influência do local de origem do trauma nos índices de admissão de pacientes submetidos à laparotomia de emergência.

OBJECTIVE to evaluate the influence of the site of trauma occurrence on the trauma scores of patients submitted to emergency laparotomy. METHODS this is a retrospective, observational, analytical study. We included 212 patients who underwent exploratory laparotomies in the period of January 2015 and December 2017. We obtained information about the accident site and vital data of the patients based on data collection through electronic and physical records. We analyzed the trauma indices of patients from Curitiba and its Metropolitan Region and the place where the patient was rescued (physical establishment or public road). RESULTS among the 212 patients studied, 184 (86.7%) were brought by the Prehospital Care Service from the city of Curitiba, and 28 (13.3%), from the Metropolitan Region of Curitiba. Twenty-five patients (17.6%) were rescued in physical establishments, while 117 (82.4%) were rescued on public roads. We observed higher values ​​of Injurity Severity Scores (ISS) in patients coming from the Metropolitan Region than in those coming from Curitiba (29.78 vs 22.46, P=0.009), but higher values ​​of Trauma and Injury Severity Scores (TRISS) in patients from Curitiba than the ones from the Metropolitan Region (90.62 vs 81.30, P=0.015). Patients rescued in public roads presented lower Revised Trauma Scores (RTS) (6.96 vs 7.65, P=0.024) and TRISS (86.42 vs 97.21; P=0.012). CONCLUSION trauma victims from sites more distant from the referral center and rescued on public roads presented worse prognosis.

Senior medical students as Trauma volunteers: is it worthwhile being on-call at a Level I Trauma Center?

Medical students usually do supervised extra-curricular activities in different fields in Brazil. Doing these activities in the resuscitation room (RR) of a Level I Trauma Center is reserved for senior medical students (after 500 hours of extra-curricular activities done at the same hospital). The aim of this study was to assess the number of different procedures a senior medical student can develop in the RR over his extra-curricular activities in this environment.
