Mobilization of critically ill patients admitted to intensive care units should
be performed based on safety criteria. The aim of the present review was to
establish which safety criteria are most often used to start early mobilization
for patients under mechanical ventilation admitted to intensive care units.
Articles were searched in the PubMed, PEDro, LILACS, Cochrane and CINAHL
databases; randomized and quasi-randomized clinical trials, cohort studies,
comparative studies with or without simultaneous controls, case series with 10
or more consecutive cases and descriptive studies were included. The same was
performed regarding prospective, retrospective or cross-sectional studies where
safety criteria to start early mobilization should be described in the Methods
section. Two reviewers independently selected potentially eligible studies
according to the established inclusion criteria, extracted data and assessed the
studies' methodological quality. Narrative description was employed in data
analysis to summarize the characteristics and results of the included studies;
safety criteria were categorized as follows: cardiovascular, respiratory,
neurological, orthopedic and other. A total of 37 articles were considered
eligible. Cardiovascular safety criteria exhibited the largest number of
variables. However, respiratory safety criteria exhibited higher concordance
among studies. There was greater divergence among the authors regarding
neurological criteria. There is a need to reinforce the recognition of the
safety criteria used to start early mobilization for critically ill patients;
the parameters and variables found might contribute to inclusion into service
routines so as to start, make progress and guide clinical practice.
