Resumen

La infección postoperatoria de la herida quirúrgica es una de las complicaciones más frecuentes de la cirugía faringolaríngea. Las infecciones son típicamente polimicrobianas, aislándose en ellas microorganismos gram-positivos, gram-negativos, aerobios y anaerobios. La contaminación de la tráquea, habitualmente estéril, se produce por la introducción directa de microorganismos desde la orofaringe a la tráquea, en el momento de la intubación. Se ha realizado un estudio prospectivo sobre 40 pacientes intervenidos quirúrgicamente por carcinoma faringolaríngeo. En el momento de realizar la traqueotomía a todos los pacientes se les tomó, con un escobillón estéril, una muestra de la pared interna de la tráquea para su estudio microbiológico. De los cultivos traqueales sólo uno de ellos fue estéril, en 3 se aisló un único microorganismo y en los 36 restantes se aislaron dos o más microorganismos, siendo lo más frecuente la flora mixta aerobia y anaerobia.

Abstract

Surgical wound infection is one of the most frequent complications in pharyngo-laryngeal external surgery. They are usually polimicro with gram-positive, negative both aerobial and anaerobial microrganisms. The trachea is usually sterile and contamination is due to the intoduction during intubation of germs from the oropharyngeal area. A retrospective study was performed including 40 patients with pharyngo-laryngeal carcinoma. When the tracheostomy was done a culture from the internal trachea wall was obtained for micro study. Only one patient had an sterile culture from the trachea. There were 3 patients with just one microorganism and all the rest had at least two, being mixed aerobial and anaerobial flora the most frequent.
