It presents for a short period of time with a transient and fluctuating evolution, with long-term outcomes of cognitive dysfunction. It has been observed mostly in extreme age groups and has been associated with factors that increase the risk of occurrence.  Objective:  To identify any factors associated with the development of postoperative delirium in the elderly following anesthesia.  Materials and methods:  An analytical cross-section study was conducted in elderly patients receiving anesthesia at a second-level hospital, from November 2016 to November 2017. The confusion assessment method was used based on 4 items for making the diagnosis of delirium. The data obtained were statistically analyzed with measures of central tendency, and the risk probability was estimated.  Results:  A total of 100 patients aged between 60 and 93 years old were studied, with postoperative delirium present in 18% of the sample. There was a statistically significant association among patients with severe pain, those with a low level of education, and those who did not have a stable partner.  Conclusion:  It is important to study the postoperative delirium factors to be able to identify the population at higher risk of experiencing postoperative delirium, with a view to reducing the number of long-term complications.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen  Introducción:  El delirio en el postoperatorio se define como un estado confusional agudo con alteraciones en la atención y conciencia. Este se presenta en un período corto de tiempo y presenta una evolución transitoria y fluctuante, con un desenlace a largo plazo en disfunción cognitiva. Se ha observado una mayor presentación en los extremos de la vida y su asociación con factores que aumentan el riesgo de presentación.  Objetivo:  Identificarlos factores asociados a la presentación de delirio postoperatorio del adulto mayor sometido a anestesia.  Materiales y Métodos:  Se realizó un estudio transversal analítico en pacientes adultos mayores sometidos a anestesia en un hospital de segundo nivel, en el periodo de Noviembre 2016 a Noviembre 2017. Se aplicó el método de evaluación de confusión (Test CAM) consistente en 4 ítems que hacen diagnóstico de delirio. Los datos obtenidos se analizaron estadísticamente con medidas de tendencia central y se calcularon probabilidades de riesgo.  Resultados:  Se estudiaron 100 pacientes con rango de edades entre los 60 y 93 años, obteniendo delirio postoperatorio en 18% de la muestra. Se encontró una asociación estadísticamente significativa entre los pacientes con dolor severo, aquellos que no contaban con algun grado de escolaridad y los que no contaban con una pareja estable.  Conclusiones:  Es importante el estudio de factores asociados a delirio postoperatorio que permitan identificar la población en más alto riesgo de desarrollarlo, buscando disminuir complicaciones a largo plazo.]]></p></abstract>
