Úlceras por presión - Medical Animation
Las úlceras por presión, también llamadas escaras, son regiones de piel que se lesionan cuando se sienta o se acuesta en una posición por mucho tiempo. Estas heridas ocurren con más frecuencia en áreas donde los huesos están cerca de la piel que incluyen talones, tobillos, caderas, coxis o codos. La presión constante en una de estas áreas comprime los vasos sanguíneos que suministran oxígeno y nutrientes vitales a la piel. Sin una suficiente cantidad de flujo sanguíneo las células de la piel finalmente mueren y se forma una úlcera por presión. Las úlceras por presión están categorizadas por grados de severidad. Una úlcera por presión de etapa uno está enrojecida, inflamada y no se vuelve pálida cuando se aplica presión en ella. Una úlcera presión de etapa dos aparece como una ampolla o úlcera abierta. Es posible que el área que rodea la úlcera esté enrojecida e irritada. Una úlcera de presión de etapa tres implica una pérdida de piel de grosor completo que se asemeja a un cráter y se extiende hasta la capa de grasa que se encuentra debajo de la piel. La etapa cuatro es la más severa. Una úlcera de etapa cuatro es una herida de grosor completo que se extiende hasta el músculo o hueso subyacente. En el 2007, el panel consultivo nacional para las úlceras por presión agregó dos etapas más supuesta lesión de los tejidos profundos y fuera de clasificación. La supuesta lesión de los tejidos profundos es una zona de color granate o morado en la piel que puede contener una ampolla llena de sangre. Tiene esta apariencia debido a los tejidos blandos llamados por debajo de la piel. Una úlcera fuera de clasificación implica una pérdida total del espesor del tejido. Sin embargo la cantidad de pérdida del tejido no puede ser determinada debido a que la úlcera está cubierta por tejido muerto. Para prevenir la infección de una úlcera por presión, el médico limpiará la herida usando agua y un jabón suave o suero. Si su herida es severa, su médico desbridará o extraerá quirúrgicamente el tejido muerto de la úlcera por presión. Para proteger e hidratar la herida, el médico posiblemente la cubra con una venda especializada.

What attorneys say about MLA and The Doe Report:
"Whether it's demonstrating a rotator cuff tear, neck movement a few milliseconds after rear impact, or a proposed lumbar fusion, the Doe Report represents an instant on-line database of medical illustration for health-care and legal professionals.

Illustrations can be purchased 'as is' or modified within hours and sent either electronically or mounted on posterboard. An illustration is worth a thousand words, as juries perk up and look intently to capture concepts that are otherwise too abstract. Start with good illustrations, a clear and direct voice, a view of the jury as 12 medical students on day one of training, and your expert testimony becomes a pleasure, even on cross examination. An experienced trial lawyer should also emphasize these illustrations at the end of trial, as a means of visually reinforcing key concepts covered.

As a treating physician, I also use these accurate illustrations to educate my own patients about their medical conditions. The Doe Report is an invaluable resource, and its authors at MLA have always been a pleasure to work with."

"We are extremely pleased with the quality of the medical exhibits and the timely manner in which they were provided. I will certainly recommend your company to my business associates who could benefit from your services. Please tell Brian Wilson [Director of Content Development, Senior Medical Illustrator] that he did an exceptional job on these exhibits."

"I wanted to take some time out to let you know what a wonderful job you did with the 'collapsed lung/fractured rib' illustrations. They were both detailed and accurate. My medical expert was comfortable working with them and he spent at least an hour explaining to the jury the anatomy of the lungs, the ribs and the injuries depicted in the illustrations. Needless to say, the jury was riveted to the doctor during his testimony.

The jury returned a verdict for $800,000.00 and I'm sure we would not have done so well if not for the visualizations we were able to put forth with your assistance. Lastly, my special thanks to Alice [Senior Medical Illustrator] who stayed late on Friday night and patiently dealt with my last minute revisions."
