Resumo

A polineuromiopatia do paciente crí­tico é uma afecção comum em pacientes graves em unidade de terapia intensiva, expostos a seus fatores de risco, sendo muitas vezes subdiagnosticada e capaz de causar prejuí­zo funcional ao paciente, incluindo a capacidade ventilatória, desencadeando insufi ciência respiratória aguda por incompetência neuromuscular. A presente revisão, realizada através de pesquisa sistemática da literatura, objetiva identificar se as alterações da contratilidade muscular na polineuromiopatia do paciente crí­tico, focando na musculatura diafragmática e da parede torácica, podem interferir no desmame do paciente. Desse modo, apresentar-se-ão os aspectos fisiopatológicos da doença, uma breve avaliação fí­sica desses aspectos e dados cientí­ficos atuais que demonstrem a interferência negativa dessa afecção muscular sobre o desmame da ventilação mecânica. Conclui-se existirem estudos evidentes de que a polineuromiopatia do paciente crí­tico aumenta o tempo do paciente na ventilação mecânica e atrasa o desmame desta, aumentando o risco de falha na extubação, necessidade de traqueostomia, morbidade e mortalidade associadas í  internação hospitalar prolongada. É importante que o fisioterapeuta esteja atento í  presença dessa doença, com o objetivo de agir precocemente para minimizar seus efeitos deletérios. Por fim, ressalta-se a necessidade de mais estudos que foquem essa doença como causa de falha no desmame da ventilação mecânica.

Palavras-chave: fisioterapia, miopatias, polineuropatias, desmame do respirador.
