Abstract

Diaphragmatic ultrasonography (US) has
been used to evaluate several respiratory diseases. Due
to portability, this examination can easily be performed at
bedside, in wards, emergency rooms and especially in the
intensive care unit To identify and analyze how diaphragmatic
ultrasonography can support safe mechanical ventilation
weaning based on scientific evidence. This is an integrative
literature review. Bibliographic survey was conducted from
September to November 2022 in the following electronic
databases: SciELO, LILACS and PubMed. A total of eight
articles were included and evaluated using the Newcastle-
Ottawa and PEDro scales, showing intermediate to high
methodological quality. In total, the studies included 482
adult volunteers, of both sexes, aged 58.09±8.03, who had
undergone invasive mechanical ventilation for at least 24 hours and were under ventilation to continue invasive ventilation
weaning. In the selected studies, we found three evaluative
variables: diaphragmatic excursion (DE) (75%); diaphragmatic
thickness (DT) (62.5%); and diaphragmatic thickening fraction
(DTF) (100%). Incorporating DT, DE and DTF into protocols for
mechanical ventilation weaning in critically ill patients seems to
support decision-making on the ideal time for weaning, reducing
extubation failure.
