¿Cómo afecta la privación de sueño durante una guardia de 24 horas las funciones cognitivas de los residentes de ortopedia y traumatología? / How does sleep deprivation during 24 hours on call duty affect the cognitive performance orthopaedic residents?

Introducción. La falta de sueño suele presentarse regularmente en los residentes de especialidades médicas durante su proceso de formación. El objetivo principal de nuestro estudio fue comparar las funciones cognitivas basales y después de la privación de sueño posguardia en residentes de ortopedia y traumatología. Material y métodos. Se han incluido en el estudio a residentes de ortopedia y traumatología y se evaluaron la atención y funciones cognitivas a través de los siguientes test: Continuous Performance Test (CPT 2), Digit Spam Directo e Inverso (Versión 5), Fluencia Fonológica de 1 letra y Pasat Test. Todas las evaluaciones basales se realizaron después de un periodo de descanso en domicilio de al menos 6 h y las evaluaciones posguardia fueron realizadas en residentes con menos de 3 h de sueño. Resultados. Diecinueve residentes fueron incluidos en el estudio. La edad media de la serie fue de 27 ± 1,89 años y 15 eran de sexo masculino. El promedio de horas de sueño basal fue de 6,5 h (rango 6-8) y posguardia de 1,5 h (rango 0,5-3). En la evaluación de CPT2 se han encontrado diferencias significativas en el número de aciertos (p = 0,007), número de omisiones (p = 0,004) y perseveraciones (p = 0,036) a la consigna planteada. No hemos encontrado diferencias significativas en los otros test. Conclusión. La falta del sueño posterior a una guardia de 24 h de ortopedia y traumatología afecta la atención de los residentes, aumentando el número de errores y omisiones (AU)

Introduction. Sleep deprivation is usually present in residents during their training program. The purpose of our study was to analyze the cognitive performance of a group of orthopaedic residents before and after 24 hours on call duty. Methods. We include orthopaedic residents and their cognitive functions were evaluated by the following tests: Continuous Performance Test (CPT 2), Digit Spam (Versión 5), 1 letter Fonologic Fluence y Pasat Test. All the tests were done after a sleeping period at home of at least 6 hours and after being on call (sleeping less than 3 hours). Results. Nineteen residents were included in the study. The median age was 27 ± 1.89 and 15 were male. The mean hours of sleeping at home was 6.5 (range 6-8) and after on call duty was 1.5 (range 0.5-3). Statistical difference were found in CPT 2 test en terms of correct answers (p=0.007), omissions (p=0.004) and perseverations (p=0.036). No significant differences were found in the other tests. Conclusion. Sleep deprivation after 24 hours on call duty affects cognitive performance of orthopaedic residents, increasing the number of errors and omissions (AU)
