Efeitos hemodinâmicos e metabólicos da movimentação passiva dos membros inferiores em pacientes sob ventilação mecânica ABSTRACT Objective: Limb movements, passively performed by a physiotherapist, have been shown to result in significant increases in critically ill patients' metabolic and hemodynamic variables. This study objective was to determine whether passive cycling leg movement increases hemodynamic and metabolic variables in sedated mechanical ventilation dependent patients.Methods: Five sedated mechanical ventilation dependent patients in a 18-bed intensive care unit of a university hospital were evaluated. Passive cycling leg movements were performed for 10min at a 30 movements/min rate. Complete hemodynamical data were recorded and arte-rial and mixed venous blood sample were collected 5 minutes before and after 5 minutes after the maneuver completion.Results: All patients had increased oxygen consumption (VO 2 ). The VO 2 increase occurred with a concomitant drop in mixed venous blood saturation (SvO 2 ), likely from both oxygen extraction ratio (O 2 ER) and cardiac index (CI) increase.Conclusion: passive cycling leg movements may influence hemodynamical and metabolic status in sedated mechanical ventilation-dependent patients.
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.
