Un método sencillo para ayudar a la comprobación del correcto posicionamiento de los tubos endotraqueales de doble luz izquierdos

This technique can be very useful in placing left-sided DLTs in situations where fiberoptic bronchoscopy is not available and if the anesthesiologist has a thorough command of the method. Our results support the routine use of this criterion as it is simple and easy to learn. It should be remembered, however, that confirmation of placement by means of fiberoptic bronchoscopy is currently the gold standard technique.
