Re-Evaluation of Systemic Early Neuromuscular Blockade and Transthoracic Ultrasound Assessment of the Diaphragm (ROSETTA)
調査の概要
詳細な説明
A growing body of evidence strongly suggests that mechanical ventilation injures the respiratory muscles, particularly the diaphragm. Due to the deleterious effects of diaphragm inactivity on diaphragm function, there are important concerns about the risk of diaphragm weakness and difficult liberation from mechanical ventilation following neuromuscular blockade. Sonographic measurements of diaphragm thickness provide a potentially useful window for studying diaphragm injury and function during mechanical ventilation.
Patients enrolled in the ROSE trial (randomizing patients with moderate-severe acute respiratory distress syndrome to receive neuromuscular blockade or control for 2 days) will be eligible for participation in this study. Study patients will undergo regular diaphragm ultrasound to assess diaphragm thickness and activity during the first week of the study. Diaphragm function will be assessed by ultrasound on study days 7, 14, 21, and 28.
ROSETTA is designed to:
- Test the feasibility of a multi-center evaluation of the diaphragm structure and function by ultrasound during mechanical ventilation;
- Determine whether neuromuscular blockade accelerates atrophy and dysfunction of the diaphragm in patients with acute respiratory distress syndrome; and
- Evaluate whether patients with greater diaphragm dysfunction exhibit worse functional outcomes compared to patients without diaphragm dysfunction.
