DIAPHRAGMATIC ULTRASONOGRAPHY AS A PREDICTOR OF VENTILATORY WEANING: A
Objectives: To review the evidence on Diaphragmatic Ultrasonography as a
predictor of success in ventilatory weaning. Methodology:Systematically
review using the PICO methodology and keywords: Ultrasound, Ultrasound,
Diagnostic imaging, Diaphragm, Weaning, Intensive Care Unit, Artificial
Respiration, Mechanical Ventilation, Ventilator Weaning. Published
cohort studies were used without language and year restrictions that
addressed the use of ultrasound to predict success in weaning and
ventilatory extubation. Studies with patients under 18 years of age,
case reports, literature reviews, results that do not bring a cutoff
value for thickness and diaphragmatic excursion and the definition of
failure in the weaning and extubation process were excluded. In
addition, the Boolean operators “and” and “or” were used.
Results:459 were found, which after exclusion due to duplication and
reading of titles and abstract, only 11 were selected by the inclusion
criteria. The samples ranged from 34 to 193 individuals. We can evidence
that the use of USG to assess the thickness and excursion of the
diaphragm in patients undergoing invasive ventilatory support is
effective in predicting success in the weaning and extubation process.
Conclusion: It is concluded that Diaphragmatic Ultrasonography has great
applicability to assess the ability to predict success or failure in
removing invasive ventilatory support.
