Niveles de contaminación acústica y sus efectos en médicos residentes de anestesiología / Noise pollution levels and its effects on resident physicians of anesthesiology

Determinar niveles de ruido mediante técnicas de sonometría, que resultan propicios parala contaminación acústica en el ambiente quirúrgico de los servicios de Sala de Operaciones de Adultos, Sala de Operaciones de la Emergencia de Adultos, Sala de Operaciones de Pediatría, Sala de Operaciones de Ginecología y Sala de Labor y Partos del Hospital Roosevelt, durante abril ­ mayo de 2017. Material y método: Estudio descriptivo transversal realizado en quirófanos del Hospital Roosevelt donde se utilizó la tercera estrategia de la NTG ­ ISO 9612 para determinar exposición al ruido ocupacional con la participación de 26 médicos residentes de anestesiología a quienes se les aplicó diversos test para identificar efectos cognitivos, trastornos del sueño y de la conducta relacionados a niveles altos de ruido. Resultados: Existe una media energética del sonido en quirófanos de entre 69.8 y 95.4 decibelios. El departamento quirúrgico con más ruido es Labor y Partos con 95.4 decibelios, el tipo de procedimiento con mayor contaminación acústica es la cirugía abdominal. El 53.85% de médicos presenta resultado anormal en pruebas cognitivas, 61.54% posee dificultad media para dormir. No existe evidencia de trastornos conductuales. Conclusiones: Los niveles de ruido en quirófanos sobrepasan al doble de lo recomendado por OMS provocando efectos cognitivos y trastornos del sueño en residentes de anestesiología. El horario fijo de labores es la jornada con mayor polución sonora en quirófanos. La fuente con mayor emisión de ruido dentro del área quirúrgica es el sistema de aspiración (AU)

Purpose: To determine noise levels using sonometric techniques, which are conducive to acoustic contamination in the surgical environment of the Adult Operating Room, Adult Emergency Operating Room, Pediatric Operating Room, Operating Room of Gynecology and Labor and Delivery Room of the Hospital Roosevelt in Guatemala, during the months of April and May, 2017. Population and methods: A cross - sectional descriptive study performed in operating rooms of the Hospital Roosevelt where the third strategy of NTG - ISO 9612 was used to determine exposure to occupational noise with the participation of 26 resident physicians of anesthesiology who were given different tests to identify cognitive effects, sleep disorders and behavior related to high noise levels. Results: There is an energetic mean of the sound in operating rooms between 69.8 and 95.4 decibels. The surgical department with the most noise is Labor and Delivery Room with 95.4 decibels, the procedure with the highest noise emission is abdominal surgery. 53.85% of physicians present abnormal results in cognitive tests, 61.54% have medium difficulty sleeping. There is no evidence of behavioral disorders. Conclusion: Noise levels in operating rooms are more than twice that recommended by whom, causing cognitive effects and sleep disorders in residents of anesthesiology. The fixed work schedule is the day with the greatest sound pollution in operating theaters. The source with the highest noise emission within the surgical area is the aspiration system (AU)

Sleep Patterns and Circadian Types of Nursing Students during Shift Schedules

PURPOSE: The purpose of this study was to investigate sleep habits, sleep disturbance, and circadian types, and to identify factors influencing sleep disturbance in nursing students. METHODS: Participants were 140 senior nursing students. The data were collected from May 19 to 27, 2008 using self-report questionnaires. RESULTS: 1) Evening type delayed sleep-wake schedules were more frequent than for morning type, especially during weekend and evening shift duty. 2) In total sleep time, there were no significant statistical differences between morning type and evening type during weekdays, weekend, day or evening shift duty. 3) On weekdays and day shift duty, the mean score for sleep disturbance was significantly higher in the evening type compared to the morning type. 4) Sleep disturbance in weekday and day shift duty was influenced by circadian types, eating habits, and gender. CONCLUSION: The circadian types are a very important factor for determining the sleep quantity and quality in nursing students.
