Iluminância em centros cirúrgicos em Cuiabá : estudo de caso

Abstract

To ensure safety in surgery, in addition to the technical elements of the procedure itself, it is necessary that the lighting conditions of the surgical center are proper, in order to reduce the variations that can alter the outcome of the procedures, to increase the level of success and to preserve the health of the professionals. This study aims to verify the accordance of the lighting levels to the Brazilian standard regarding minimum levels of illuminance in the operating room, compare these levels with the values btained in computer simulations for lighting in order to validate its use for lighting projects in these environments and to verify compliance with the recommendations of the IESNA (American Society Illuminating Engineering) for lighting Units Health Assistance. For this, a profile of illuminance in the operating room in three health institutions in this Cuiabá was built, based on Brazilian standards and the recommendations of the IESNA, and computer simulations were conducted regarding lighting levels in these environments. The data were collected through observation of the physical characteristics of the rooms, the facilities available for the lighting the workplace, the measurement of illuminance in the operating room and computer simulations. The equipment used for the research were: a measuring tape, a luximeter, a camera and the Dialux software. The criteria used for the analysis were: the Brazilian standard for lighting, which determines the minimum levels of lighting for different environments, and the recommendations for lighting for hospitals and health care facilities of the IESNA. The results indicate that the lighting systems of surgical centers evaluated do not meet most of the recommendations and normative criteria used as a basis for this work in all environments, and the use of the Dialux software can be viable to carry out lighting projects in these environments with some considerations.
