Diaphragmatic dysfunction at admission in intensive care unit: the value of diaphragmatic ultrasonography
- 693 Downloads
Although the diaphragm is the main respiratory muscle, little is known about the epidemiology of diaphragmatic dysfunction (DD) especially upon admission in the intensive care unit (ICU). Using endotracheal pressure variations after bilateral magnetic stimulation of phrenic nerves, Demoule et al.  reported a high prevalence of DD at ICU admission. In this study, DD is associated with disease severity, sepsis and poor prognosis, and it appeared as a sepsis-related organ failure. With the development of ultrasound in medicine, DD can now be diagnosed by diaphragmatic ultrasonography (DUS). However, studies related to this topic in the ICU mainly focused on diaphragmatic weakness acquired during ICU stay or post-cardiac surgery DD [2, 3, 4, 5]. Therefore, we report our experience of DD diagnosis using DUS upon admission in our ICU in patients with acute respiratory failure (ARF).
