RESUMO
The COVID-19 pandemic has caused an overload on the health care system on a global scale. Because the disease affects the respiratory system, patients may require ventilator equipment for breathing, and consequently, numerous tracheal intubations have been performed. The video laryngoscope is a medical device that aids this procedure. It is used by anesthesiologists to visualize the anatomical structures of the larynx during tube insertion. Unfortunately, many hospitals worldwide are unable to afford sufficient units of this medical device. To satisfy the high demand, low-cost alternatives employing three-dimensional (3D) printing techniques have been developed for health care professional's use. With the intention of ensuring the efficiency, reproducibility, and security of the 3D-printed laryngoscope, this article presents a novel model with versions for pediatric and adult use, which was developed under the supervision of a medical team. The mechanical performance of 3D-printed prototypes (of the proposed models) was evaluated using mechanical assays, and the results indicated a satisfactory safety factor.
RESUMO
Introdução: Estudar a prevalência do tabagismo entre os acadêmicos dos cursos de Biomedicina, Fonoaudiologia, Medicina e Nutrição da Universidade Federal de Ciências da Saúde de Porto Alegre. Métodos: Foi realizado estudo transversal para investigar o hábito tabágico entre estudantes universitários da área da saúde, com a utilização de um questionário autoaplicável. Fumantes foram definidos como aqueles que fumavam um ou mais cigarros por dia há pelo menos um mês. Resultados: Foram obtidas respostas de 533 acadêmicos (95,7% do total) e a prevalência geral foi de 4,9% (IC95% 3,06,8). Não houve diferença estatisticamente significativa entre os cursos. A média de cigarros fumados por dia foi de 3,8. Dezesseis por cento iniciaram o hábito durante o curso e 64% declararam ter vontade de parar de fumar. Conclusão: A prevalência geral do tabagismo foi de 4,9% e não se identificou diferença significativa entre os cursos (AU)
Introduction: To study the prevalence of smoking among students of biomedicine, speech therapy, medicine, and nutrition at the Federal University of Health Sciences of Porto Alegre. Methods: A transversal study was carried out to explore the smoking habits of undergraduates in health-related courses through a self-applied questionnaire. Smokers were defined as those who have smoked one or more cigarettes a day for at least one month. Results: 533 students responded to the questionnaire (95.7% of the total) and the smoking prevalence was 4.9% (CI95% 3.06.8). There was no significant difference across the courses. The mean number of cigarettes smoked per day was 3.8. Sixteen per cent (18%) started smoking during the course, and 64% reported to be willing to quit smoking. Conclusion: The overall prevalence of smoking was 4.9%, and no significant difference was found between the courses (AU)
