Early Identification of Patients in Surgical Intensive Care With a Risk of Acute Respiratory Distress Following Visceral Surgery (ODR)

Today there are few studies in the literature involving patients in an ICU following major visceral surgery. There are thus few results about the prognostic value of pulmonary extravascular water in this population of patients, but also the prognostic value of pulmonary extravascular water measured at the bedside using pulmonary ultrasound.

In addition, pulmonary ultrasound will be combined with echocardiography to measure left ventricular function (LVEF) and to study the profile of the mitral valve to assess filling pressure in patients with immediate post-operative ventilation. This will make it possible to distinguish between increases in pulmonary extravascular water associated with high filling pressure and increased pulmonary water associated with low filling pressure: characteristic of lesional oedema.

The aim of this study is to determine the prognostic value of extravascular pulmonary water (PEVW) diagnosed using pulmonary ultrasound in patients admitted to an ICU following scheduled or emergency visceral surgery in the onset of acute respiratory distress requiring invasive mechanical ventilation, or prolonged post-operative intubation, or non-invasive.
