Use of Ultrasound for Early Identification of Patients at Risk of Swallowing Disorders Acquired in the ICU

Swallowing disorders (SD) are particularly common after extubation in the ICU and may be associated with an increased risk of lung disease, increased length of hospital stay, and a higher risk of early reintubation. In contrast, early detection of SDs has been shown to be associated with a decrease in these complications. Thus, there is a need for rapid and reliable assessment of SDs in ICU patients before the withdrawal of mechanical ventilation. Videofluoroscopy (VFS) and nasofibroscopy (NF) are the gold standard examinations for diagnosing SD. However, these two examinations are not feasible in intubated patients. In this context, ultrasound appears to be a promising alternative to identify patients at risk of SD after extubation. This examination can be performed at the intubated patient's bedside and can be used evaluate the mobility of the structures involved in swallowing. Many studies have already shown the interest of ultrasound in the evaluation of SD but none has focused on intubated patients under respiratory assistance. The objective of the present study is to evaluate the value of ultrasound in identifying patients at risk of presenting SD after extubation. This monocentric study will take place in the Intensive Care Unit (ICU) of the Dijon University Hospital. The duration of participation in this research will be equal to the length of stay in the ICU. During their stay, patients will undergo ultrasound and nasofibroscopy. Information on the characteristics of the ICU stay will be collected at discharge.
