Critically Ill | Ultrasound of the Diaphragm in ICU Patients

Critically Ill research study

What is the primary objective of this study?

Diaphragmatic dysfunction is an important complication of mechanical ventilation. Critically ill patients admitted in a teaching hospital intensive care unit will be evaluated with diaphragm ultrasound to investigate predictors of diaphragmatic dysfunction and the clinical course of these patients. Vascular surgery patients (aortic abdominal surgery) might also be included and assessed with diaphragm ultrasound before and after surgery irrespectively of the need of intensive care unit. On December 2014 the Etical committee approved an amendment to include the possibility to study elective aortic abdominal surgery patient to assess the relationship between surgery related diaphragmatic dysfunction and postoperative respiratory complications.

Who is eligible to participate?

Inclusion Criteria: - adult plus admitted in ICU plus invasive or non-invasive mechanical ventilation or - adults aortic vascular surgery Exclusion Criteria: - < 18 years

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Critically Ill

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
