RESUMO: Objetivo:Conduziu-se este estudo prospectivo a fim de avaliar-se a influência do uso da braçadeira sobre o acúmulo de coágulos dentro dos drenos pleurais. Método: Os drenos pleurais foram pesados logo após sua retirada, lavados e secados e pesados novamente. A diferença entre a primeira e a segunda pesagem foi admitida como a quantidade de coágulos acumulada. Resultados: Houve maior acúmulo de coágulo nos drenos temporariamente obstruídos por braçadeira em relação àqueles não obstruídos. Conclusão: Notou-se, neste estudo, maior acúmulo de coágulo dentro de drenos pleurais obstruídos, mesmo que intermitentemente, o que pode levar ao mau funcionamento de todo o sistema de drenagem. A discussão sobre o correto uso dos drenos pleurais deve ser constante e fazer parte de programas de educação continuada para médicos e enfermagem, a fim de que este sistema, amplamente utilizado e altamente eficiente, seja otimizado (Rev. Col. Bras. Cir. 2008; 35(2): 079-082). AgradecimentosAgradecemos à colaboração dos laboratórios de patologia clínica do Hospital Estadual Sumaré e do Hospital das Clínicas da Unicamp por ceder seus equipamentos de precisão e seu espaço físico. Congratulamo-nos com a equipe de enfermagem do Hospital Estadual Sumaré pela predisposição à discussão e à educação continuada. ABSTRACT Background: A prospective study was done to evaluate the influence of clamp usage on clot formation inside thoracic drains.Methods: Each drain was weighed soon after removal; they were then washed, dried and weighed again. The difference between the first and second weights was taken as the amount of clot deposit formed. Results: We found more clots accumulated inside the drains that were temporarily obstructed by the clamp. Conclusion: In this study, there were more clots formation inside thoracic drains clamped, even if they were occluded intermittently. This can lead thoracic drains to function improperly. The discussion about the correct usage of thoracic drains must be a subject for educational programs for physicians and nurses, to aim for the safest use of this widely used and highly efficient system.
This was a retrospective analysis of the medical charts of 145 patients treated at the Bronchoscopy and Thoracic Surgery Clinic of the Hospital das Clínicas da Universidade Estadual de Campinas (HC-Unicamp, State University of Campinas Hospital das Clínicas) over a period of 10 years. There was a significant difference related to the site of first medical visit (Unicamp-HC versus other institutions) in terms of the time elapsed between the suspicion of bronchial aspiration and the actual respiratory endoscopic examination. However, no significant difference was found in the rate of positive results. The low number of referral centers that provide emergency respiratory endoscopy can negatively influence the treatment of patients under suspicion of bronchial aspiration, jeopardizing the overall recovery in the mid- and long-term.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
