Análise comparativa das características do trauma entre idosos com idade superior e inferior a 80 anos / Comparative analysis of trauma characteristics between elderly and superelderly

OBJETIVO: comparar as características do trauma entre idosos e "superidosos". MÉTODOS: análise retrospectiva dos protocolos de vítimas de trauma fechado com idade igual ou superior a 70 anos. Os idosos de idade entre 70 e 79 anos foram incluídos no grupo I, os de idade igual ou maior de 80 anos no grupo II. Análise estatística foi realizada através dos testes t de Student, qui-quadrado e Fisher, considerando p<0,05 significativo. RESULTADOS: Foram incluídos no estudo 281 doentes (grupo I-149; grupo II-132). A idade variou de 70 a 99 anos (79,1 ± 6,7 anos), sendo 52,3% do sexo masculino. Os superidosos se caracterizaram por apresentar menor média de AIS em abdome (0,10 ± 0,59 vs. 0,00 ± 0,00; p=0,029), menor frequência de vítimas do sexo masculino (59,1% vs. 44,3%; p=0,013), maior frequência de queda da própria altura (44,3% vs. 65,2%; p=0,028) e menor frequência de fraturas de membros superiores (9,4% vs. 2,3%; p=0,010). Não observamos diferença significativa na comparação das demais variáveis entre os grupos. CONCLUSÃO: O trauma em idosos é um grave problema de saúde pública, com tendência à piora progressiva pelo envelhecimento da população. Os dados deste estudo nos auxiliam com uma visão mais clara do trauma nos superidosos, um subgrupo que merece atenção especial.

OBJECTIVE: To compare the characteristics of trauma in the elderly under and over 80-years-old. METHODS: We conducted a retrospective analysis of protocols of blunt trauma victims aged over 70 years. Individuals aged between 70 and 79 years were included in group I, those aged 80 years or greater in group II. Statistical analysis was performed using the Student t, chi-square and Fisher tests, considering p <0.05 as significant. RESULTS: The study included 281 patients (group I-149, group II-132). The age ranged between 70 and 99 years (79.1 + 6.7 years), with 52.3% male. Group II had lower average abdomen AIS (0.10 + 0.59 vs. 0.00 + 0.00, p = 0.029), lower incidence of male victims (59.1% vs. 44 , 3%, p = 0.013), higher incidence of falling from standing height (44.3% vs. 65.2%, p = 0.028) and lower frequency of upper limb fractures (9.4% vs. 2.3 %, p = 0.010) than Group I. There was no significant difference in comparison of other variables between the groups. CONCLUSION: Trauma in the elderly is a serious public health problem, with a tendency to progressive worsening with population aging. Data from this study help us with a clearer picture of trauma in the over-80 elders, a subgroup that deserves special attention.

Accidentalidad por fluidos biológicos en profesionales de laboratorios clínicos de Maracaibo, Venezuela / Biological fluid-related accidents amongst professionals working in clinical laboratories in Maracaibo, Venezuela

Objetivo Determinar la exposición laboral accidental a fluidos biológicos por contacto percutáneo en el personal Bioanalista de Laboratorios Clínicos públicos, sus factores asociados y el cumplimiento de medidas post exposición biológica. Métodos Se realizó un estudio descriptivo transversal, la muestra fue de 156 bioanalistas adscritos a laboratorios clínicos del área metropolitana del estado Zulia. Para la recolección de datos se aplicó un instrumento de escalas que exploró la exposición percutánea, los factores vinculados y el cumplimiento de medidas post exposición biológica. Resultados Se evidenció exposición por accidentes percutáneos, representados principalmente por pinchazos y cortaduras, detectados en razón de su ocurrencia en un nivel moderado (media entre 2-3,99). Como factores vinculados a la accidentabilidad percutánea, se registra la ocurrencia en nivel moderado con diversas agujas huecas, con sangre y hemoderivados, en manos y dedos, con una severidad superficial, en áreas de toma y procesamiento de muestras durante el re-encapuchado de objetos punzo cortantes. Un nivel de mediano cumplimiento se obtuvo para el manejo post exposición. Existe relación entre la exposición percutánea con el nivel de cumplimiento detectado para el manejo post exposición p <0,001. Conclusión La magnitud y características de la exposición a fluidos biológicos detectada en este colectivo laboral reviste una problemática que puede impactar en la salud del personal y debe ser abordada institucionalmente para una efectiva gestión de prevención y control de riesgo.

Objective Determining the occupational exposure to biological fluids of medical technicians working in public clinical laboratories caused by accidental percutaneous contact, associated factors and compliance with post-exposure biological measures. Methods This was a descriptive cross-sectional study. The sample consisted of 156 medical technicians assigned to clinical laboratories in the metropolitan area of Zulia state in Venezuela. Data was collected by applying an instrument for exploring exposure and related factors, as well as compliance with established post-biological exposure measures. Results There was evidence of exposure caused by percutaneous accidents, mainly represented by a moderate level of needle-pricks and cuts (2-3.99 mean). There was a moderate level of factors regarding percutaneous injury in the hands and fingers associated with hollow needles, blood and blood products and superficial severity in sample taking and processing areas when recapping needles or handling sharp or cutting objects. A medium level (2-3.99 mean) of compliance was obtained for post-exposure handling. A significant correlation was found (p<001) between percutaneous exposure and level of compliance with post-exposure management. Conclusion The magnitude and characteristics of exposure to biological fluids detected in this work represents a problematic situation which can affect staff health and must be approached by institutions to ensure effective prevention management and risk control.

Hernia diafragmática traumática / Diaphragmatic traumatic hernia

Introducción: las hernias diafragmáticas traumáticas comúnmente ocurren posteriores a trauma penetrante cerrado. Debido a las lesiones coexistentes y a la naturaleza silenciosa de las lesiones diafragmáticas, el diagnóstico fácilmente se omite. El objetivo de este estudio fue describir las características clínicas de pacientes consecutivos con hernias diafragmáticas traumáticas tratadas quirúrgicamente en nuestra institución. Material y métodos: cohorte prospectiva de pacientes tratados durante un periodo de seis años. Evaluamos edad, sexo, tipo de mecanismo del trauma, tipo de hernia, método diagnóstico, órganos herniados, lesiones asociadas, tiempo de evolución, morbilidad y mortalidad. Los resultados se describen como frecuencias y medidas de tendencia central y de dispersión. Se empleó χ2 y prueba exacta de Fisher para explorar asociación y riesgo. Resultados: se incluyeron 23 pacientes, 19 fueron hombres (82.6 %) y cuatro mujeres (17.4 %). En nueve pacientes (39.1 %) fueron diagnosticadas hernias diafragmáticas agudas y en 14, hernias crónicas (60.9 %). En 18 (78.3 %) el diagnóstico se hizo mediante radiografía de tórax y la mayoría correspondió a hernias crónicas. La historia médica de trauma toracoabdominal cerrado estuvo presente en 95.7 %, en la mayoría relacionado con accidentes vehiculares. Las principales lesiones asociadas fueron trauma encefálico, fracturas costales y contusión pulmonar. La morbilidad se observó en seis pacientes, todos con hernias crónicas. No hubo mortalidad. Conclusiones: la hernia diafragmática traumática es una entidad clínica poco frecuente y constituye un verdadero desafío debido a las dificultades para el rápido y correcto diagnóstico. En etapa crónica hay mayor riesgo para complicaciones tardías como estrangulamiento y necrosis de vísceras.

BACKGROUND: Traumatic diaphragmatic hernias commonly occur after blunt and penetrating trauma. Due to coexisting injuries and the silent nature of the diaphragmatic injuries, the diagnosis is easily missed. We undertook this study to describe the clinical characteristics of consecutive patients with traumatic diaphragmatic hernias treated surgically at our institution. METHODS: We conducted a prospective cohort of patients treated during a 6-year period. We assessed variables such as age, gender, type of mechanism of trauma, type of hernia, methods of diagnosis, herniated organs and associated lesions, time of evolution, morbidity and mortality. Results are described as frequencies, dispersion and central tendency measures. Chi(2) and Fisher's exact tests were used to explore association and risks. RESULTS: Twenty three patients were included, 19 men (82.6%) and 4 women (17.4%). Acute DTH were diagnosed in nine patients (39.1%) and 14 cases presented as chronic DTH (60.9%). In 18 cases (78.3%) the diagnosis was made by chest x-ray and most corresponded to chronic hernias. Medical history of blunt thoracoabominal trauma was present in 95.7% of the cases, most related to car accidents. The principal associated lesions were head injuries, rib fractures and lung contusion. morbidity was observed in six patients, all with chronic hernias. there was no mortality. CONCLUSIONS: DTH is a rare clinical entity and constitutes a true challenge due to difficulties for a rapid and correct diagnosis. In the chronic stage there is an increased risk for late complications such as visceral strangulation and necrosis.
