dc.description | Introducción: Se conocen los beneficios del uso de los tubos endotraqueales con neumotaponador, aunque dicha práctica tiene un impacto sobre el trabajo respiratorio durante el acto anestésico sin embargo se propone estudiar las consecuencias físicas de la variación en la longitud de los tubos para compensar dicha perdida de flujo, con base en la ley de Hagen-Poiseuille. Metodología: Se realizó un estudio experimental in vitro, en el cual se realizaron mediciones repetidas de flujo, variando la longitud y diámetro de diferentes tubos endotraqueales pediátricos (desde calibre 3.5mm hasta 6.5mm), con longitudes de 20cm, 15 cm, 10 cm y manteniendo su longitud original. Se analizaron los datos con el fin de medir el impacto sobre el flujo. Resultados: A pesar que los resultados muestran diferencias estadísticamente significativas (p0,000), la variación en la longitud de los tubos endotraqueales pediátricos tiene mucho menor impacto sobre la variación en el flujo, que la modificación del diámetro. Discusión: Si bien la práctica de acortar la longitud de un tubo endotraqueal pediátrico puede ayudar a reducir el espacio muerto y la retención de CO2, el impacto que tiene sobre el flujo es poco. Cuando se trata de disminuir el trabajo respiratorio de un niño en ventilación espontánea durante el acto anestésico, se debe escoger de forma apropiada el calibre de tubo correspondiente para la edad. | spa |
dc.description.abstract | Introduction: The benefits of using endotracheal tubes with cuff are well-known, although this practice has an impact on the work of breathing during pediatric anesthesia; however, it´s intended to study the physical consequences of variation in the length of the tubes to compensate for the loss flow, based on the law of Hagen-Poiseuille. Methodology: An experimental study was conducted in vitro, in which repeated measurements of flow were performed, varying the length and diameter thereof, with pediatric endotracheal tubes of different sizes (from 3.5mm to 6.5mm), with lengths 20 cm, 15 cm, 10 cm and its original length. Data were analyzed to measure the impact on flow. Results: Although the results show significant differences statistically (p 0,000), the modification of the length of the endotracheal tubes has less effect on flow, compared to the impact that the change in diameter has on it. Discussion: Although the change in length of endotracheal tubes can help to reduce the death space and CO2 retention, the impact that it has on flow in minimal. When it comes about reducing the work of breathing of a child in spontaneous ventilation during general anesthesia, physicians must choose the proper diameter according to the age. | eng |
