Abdominal Muscle Thickness in Mechanically Ventilated Patients

Abdominal Muscle Thickness in Mechanically Ventilated Patients During Spontaneous Breathing Trials

The purpose of the study is to determine to what extent the abdominal muscles contribute to airway pressure, in order to investigate the correlation between muscles weakness and extubation outcome in mechanically ventilated patients. In addition the reliability of the sonographic measurements will be assessed.

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Mechanically ventilated patients
Abdominal muscles ultrasound
Abdominal muscles ultrasound during a spontaneous breathing trial using the M-mode to calculate the thickening fraction of the anterior and lateral abdominal muscles under multiple circumstances (tasks performed by the patients)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlation between thickening fraction and SBT outcome
Time Frame: Measurements will be performed before SBT
Correlation between thickening fraction of each muscles evaluated by ultrasound before the SBT and the SBT outcome.
Measurements will be performed before SBT

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlation between the pressures generated by respiratory muscles and SBT outcome
Time Frame: Measurements will be performed before SBT
Correlation between the pressures generated by respiratory muscles during the ultrasound measurements (Twice Transdiaphragmatic pressure, TwPdi; maximal inspiratory pressure, MIP) and SBT outcome
Measurements will be performed before SBT
Inter-rater agreement
Time Frame: Measurements will be performed before SBT
Concordance of measurements of abdominal muscle thickness and thickening fraction in mechanically ventilated patients performed by two different observers will be evaluated.
Measurements will be performed before SBT
