Resumo: | Background - In low-temperature working environments, physiological reactions aimed at adjusting thermal balance occur, leading sometimes to cardiovascular overload. However, the cold is often a key factor in the production, processing, and packaging of products, especially in the food industry, which makes occupational exposure to a cold environment a reality. This study’s main aim is to study the work conditions and to identify electrocardiographic alterations in individuals working in a meat processing center (MPC), facing low temperatures (<8ºC). Methods - Environmental parameters such as temperature, relative humidity, and air velocity were measured through specific equipment. It calculated the index IREQ (required clothing insulation), the characterization of basic clothing insulation, and the metabolic activity per job. Electrocardiographic monitoring was obtained through Holter’s ambulatory electrocardiography. Relevant information was also collected through Holter’s diary, a questionnaire, and a digital thermometer. Results/Discussion - The sample is subject to a slight degree of hypothermia which can be due to the fact that no evidence of thermal stress was found and to the confluence of factors such as: the large number of workers that wear additional clothing besides the working clothes provided by the MPC, and the high metabolic rate inferred by the analysis of the cardiac frequency. The results of the study are different from those found in the bibliography used – in this study’s sample, no electrocardiographic expression of hypothermia has been observed. Conclusion - In order to improve working conditions, some corrective organizational measures can be implemented, since the control of the thermal environment is not feasible. Although there are no electrocardiographic alterations it is important to include cardiovascular exams in periodical medical examinations (in addition to the electrocardiogram, should also perform a Holter ambulatory electrocardiogram, 24-hour blood pressure monitorization, and echocardiogram) since working in cold environments can cause cardiac changes likely to come up or aggravate due to prolonged exposure. |

Introdução - Em ambientes laborais de baixa temperatura ocorrem reacções fisiológicas destinadas a ajustar o equilíbrio térmico que podem conduzir a sobrecarga cardiovascular. Contudo, em várias áreas de actividade o frio é um factor essencial para a produção, o que torna a exposição ocupacional uma realidade incontornável. Este estudo teve como objectivo identificar alterações electrocardiográficas em trabalhadores de uma Indústria de Processamento de Carnes (IPC), em condições laborais de baixa temperatura (<8ºC) e caracterizar o ambiente térmico. Metodologia - Foram medidos por equipamento específico os parâmetros ambientais (temperatura, humidade relativa e velocidade do ar). Foram calculados o índice IREQ (isolamento requerido pelo vestuário) e o nível de actividade metabólica por posto de trabalho. A monitorização electrocardiográfica foi efectuada através de electrocardiografia ambulatória de Holter (EcgAH). Para recolha de dados complementares ao EcgAH, foram também utilizados um diário de EcgAH, um questionário e um termómetro digital. Resultados/Discussão - A amostra em estudo estava sujeita a um grau hipotérmico ligeiro, podendo dever-se à ausência de exposição a stress térmico e à confluência de factores como: a elevada percentagem de trabalhadores que utiliza vestuário adicional além do protector cedido pela IPC e a elevada taxa metabólica inferida pela análise da frequência cardíaca. Os resultados deste estudo divergiram dos da literatura consultada, não se identificando qualquer expressão electrocardiográfica comum na hipotermia. Considerações finais - Sugere-se a implementação de algumas medidas de carácter organizacional uma vez que, por questões produtivas, é impossível alterar as condições térmicas. Apesar de não se terem identificado alterações electrocardiográficas, considera-se pertinente integrar exames do foro cardiovascular (para além do electrocardiograma, também o electrocardiograma ambulatório de Holter, a medição ambulatória da pressão arterial e ecocardiograma) nos exames realizados no âmbito da medicina do trabalho, pois ambientes refrigerados podem promover alterações a nível cardíaco.Escola Superior de Tecnologia da Saúde de Lisboa (Instituto Politécnico de Lisboa)2009-05-15info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.25758/set.224https://doi.org/10.25758/set.224Saúde e Tecnologia; No. 03 (2009): Maio 2009; 25-30Saúde & Tecnologia; N.º 03 (2009): Maio 2009; 25-301646-9704reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://journals.ipl.pt/stecnologia/article/view/755https://journals.ipl.pt/stecnologia/article/view/755/644Direitos de Autor (c) 2023 Saúde & Tecnologiainfo:eu-repo/semantics/openAccessSilva, AnaViegas, SusanaFonseca, VirgíniaIsidoro, AndreiaAnselmo, AnaOliveira, AnaAlbuquerque, PaulaLobato, João2023-05-12T08:30:25Zoai:journals.ipl.pt:article/755Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T17:42:46.009328Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
