El móvil puede ayudar a diagnosticar fracturas






Yo lo veníamos diciendo, los teléfonos móviles que llevamos en el bolsillo lo van a cambiar todo. Unos investigadores han hecho pruebas para diagnosticar fracturas óseas usando un móvil y un estetoscopio. Es una vieja técnica que ya se empleaba hace mucho tiempo. Se colocaba un diapasón vibrando en una extremidad del hueso y con el fonendo se escuchaba el sonido en el otro extremo. Luego se comparaba con el otro lado. Si había disminución de la intensidad del sonido se sospechaba fractura. El artículo actual hace lo mismo con un móvil en vibración. Recomiendan prudencia pero parece que puede dar una idea.

Novel Approach to the Diagnosis of Fractures in an Austere Environment Using a Stethoscope and a Cellular Phone.

Abstract

BACKGROUND:

Fracture diagnosis in the austere environment where radiographic tests are not available can be a challenge. In the past, a diagnostic technique has been described using a tuning fork and stethoscope to assess decreased sound conduction in the fractured extremity. In this study, we evaluate the use of a cellular phone's vibrate function and a stethoscope to limit equipment carried by expeditionary practitioners.

OBJECTIVE:

The purpose of this study was to evaluate the accuracy of fracture diagnosis using a cellular phone and stethoscope.

METHODS:

This is a pilot study to assess the usefulness of the above technique before clinical implementation. In 3 cadavers, we created fractures of the humerus and femur. Twenty-seven emergency medicine residents and an attending physician performed the diagnostic technique.

RESULTS:

Overall, the use of the cellular phone and stethoscope resulted in a sensitivity of 73% (95% confidence interval [CI]: 0.64 to 0.81) and a specificity of 83% (95% CI: 0.77 to 0.88), with a positive predicted value of 68% (95% CI: 0.59 to 0.77) and a negative predicted value of 86% (95% CI: 0.81 to 0.90). Positive likelihood ratio was 4.3, and negative likelihood ratio was 0.32.

CONCLUSIONS:

The use of a cellular phone and stethoscope may be a useful tool for the diagnosis of fractures in the austere environment. However, further study is needed to validate these findings in the clinical environment.
