Efeitos da fisioterapia motora nas funções respiratórias de pacientes dependentes de ventilação mecânica invasiva

Abstract

Background: Invasive Mechanical Ventilation (IMV) therapy is often associated with several respiratory complications in the intensive care unit (ICU). It is necessary removal the mechanical ventilation as early as possible, because of the complications associated with MV are common. Exercise therapy is considered central element in most care plans in purpose to reduce these complications and thus to reduce the process of weaning from MV. Objective: To investigate the effects of mobilization, on respiratory functions, in patients dependent on mechanical ventilation. Materials and Methods: This is a narrative review of literature that was done in electronic databases PubMed and VHL, without delimiting period of publication of articles, from descriptors "prolonged mechanical ventilation", "exercise", "physical therapy" "weaning", "muscle strength", "training". Results: 48 articles were available. Were excluded 42 articles with differents outcomes of this study and two review articles in the literature. Four articles were added in this present study. Of the nine articles selected for this review, seven found out the result of mobilization on respiratory muscle strength or respiratory variables in the patient in VM, one evaluated the patient weaned from MV after 48-96 hours and one study assessed the impact of the degree of peripheral muscle strength in successful decannulation of tracheostomized and dependent VM. Conclusion: Although the lack of studies that address the use of mobilization, as a therapeutic resource, seems to prevent and reverse respiratory complications, helping the weaning of the VM.
