Evaluation of Diaphragmatic Ultrasound Indices as Predictors of Successful Liberation From Mechanical Ventilation in Subjects With Abdominal Sepsis.

Background: Sepsis-induced diaphragmatic dysfunction is one of the main risk factors of failure to liberate patients from mechanical ventilation. Several studies addressed diaphragmatic ultrasound as a valuable tool in the assessment of diaphragmatic function during liberation from mechanical ventilation in different populations. However, none of these studies examined the use of diaphragmatic ultrasound to predict failure of liberation from mechanical ventilation in subjects with sepsis METHODS: A prospective observational study was done with subjects on mechanical ventilation and with abdominal sepsis.
