Paresia diafragmática bilateral idiopática

Abstract: We report the case of a patient with severe dyspnea upon reclining. Lung disease, neuromuscular disorders and heart disease were ruled out. However, during the course of the investigation, bilateral diaphragmatic paresis was discovered. A key sign leading to the diagnosis was evidence of paradoxical respiration in the dorsal decubitus position. When the patient was moved from the orthostatic position to the dorsal decubitus position, oxygenation and forced vital capacity worsened. The orthostatic fluoroscopy w… Show more

“…Despite its ease of use, the test has several drawbacks: it has only rarely been compared to a reference technique, making estimates of its sensitivity and specificity imprecise; it is dependent on patient effort and cooperation and only provides a semi-quantitative evaluation of diaphragm function, making repetitive prospective measurements difficult to compare. In addition, it should not be used in the setting of bilateral diaphragm weakness, as the abnormal breathing pattern observed in this setting may obscure radiological findings and result in false negatives [98,113,114,115]. …”

“…Changes in FVC after interscalene blocks are common, but they are not observed in all cases. Spirometry might be normal, even in the presence of bilateral diaphragmatic dysfunction, especially when done with patients in the orthostatic position 19 .…”

“…Podemos considerar que tal comportamento se deve ao fato que o sujeito 5 é, entre os sujeitos da pesquisa, um dos que possui o menor tempo de lesão. Conforme estudos de McColl e Tzelepis citados por Pereira et al (17), após revisarem o uso do treinamento muscular inspiratório em pacientes com doenças neuromusculares, concluíram que quando há um comprometimento maior a recuperação é mais difícil; porém, nos estágios iniciais das doenças, o treinamento muscular respiratório pode melhorar a função muscular respiratória.…”

“…Podemos observar também que a relação mostrada no Gráfico 2, com relação ao tempo de lesão e à diferença da PImáx, foi significativa, uma vez que o sujeito 5, como dito anteriormente, foi o que mais teve ganho, mostrando que quanto mais cedo tiver início o treinamento, melhores são as chances para ganho de força e endurance muscular. O tempo é um item preponderante para o prognóstico, uma vez que o paciente com um tempo maior de lesão terá mais dificuldade no fortalecimento muscular respiratório, segundo McCool e Tzelepis citados por Pereira et al (17). Esse paciente deverá ser submetido a maior número de atendimentos para que consiga chegar ao melhor desempenho do sistema muscular respiratório, apesar de não haver estudos que comprovem tais resultados obtidos nesta pesquisa.…”
