RESUMO
El objetivo de este estudio fue evaluar la tendencia de los pacientes con fracturas mandibulares asociados a accidentes laborales. Se realizó un estudio descriptivo retrospectivo en todos los casos de fracturas mandibulares que asistieron al servicio de cirugía maxilofacial del Hospital Clínico Mutual de Seguridad C.Ch.C., Santiago de Chile en un periodo de 4 años (enero 2009 - diciembre 2012). Todas las fracturas mandibulares fueron consignadas. La información fue recopilada a través de revisión de fichas clínicas electrónicas. Entre los años 2009 al 2012 se presentaron un total de 74 pacientes incluidos en el estudio con 102 rasgos de fracturas mandibulares. La fractura más común fue la de cóndilo mandibular (35 pacientes). Se observó una tasa de complicaciones del 8%. Los resultados mostrados en este estudio están en línea con la literatura y el análisis de este reporte provee información para el diseño de planes de prevención de riesgos, especialmente para desarrollar medidas de protección facial. Nivel de Evidencia: Tipo II. Estudio descriptivo.
The objective of this study was to evaluate the tendency of patients with mandibular fractures associated with working accidents. A retrospective descriptive study was performed in all cases of mandibular fractures who attended the maxillofacial surgery service at the Clinical Hospital Mutual Seguridad C.CH.C. Santiago de Chile, in a 4-year period (January 2009 - December 2012). All mandibular fractures were recorded. The information was collected through review of electronic medical records. Between 2009 and 2012, 74 patients were included in the study with 102 lines of mandibular fractures. The most common fracture was the mandibular condyle (35 patients). The complication rate was 8%. The results shown in this study are in line with the literature and the analysis of this report provides information for the design of risk prevention plans, especially in developing measures of facial protection.

The action of 2-3 mg/kg of morphine on the threshold of electrical fibrillation of the ventricle (TVF) in anesthetized dogs has been studied. The basal TVF was 10.5 +/- 4.9 mA, increased to 20.2 +/- 7.7 mA (P 0.005) with the administration of this drug. Comparatively, the effect of morphine on the TVF is similar to that of propranolol and bretilium and more effective than procainamide. The mechanism by which it acts is not well known. Perhaps it is due to a homogenization of refractory periods in the ventricle as well as a possible morphine-catacholamine interaction. Morphine in dosis of 2-3 mg/kg could occupy a place among the antiarrhythmic drugs of choice with antifibrillatory action, with important usefulness in the field of anestesiology of cardiopaths.
