Abstract

Introduction: No data is available on respiratory insufficiency as a reason for a prolonged ICU LOS in patients admitted to the ICU after elective surgery. The role of the diaphragm has not been researched in these patients, although research suggests a relationship between diaphragm variables and lung function. Several techniques are available to visualize the diaphragm, of which chest radiography and ultrasound are the most used. We tried to objectify a correlation between chest radiographs and ultrasound variables to be able to predict if patients can be identified who are at high risk for a prolonged ICU LOS due to respiratory insufficiency. Methods: Chest radiograph measurements were performed on all eligible patients and analyzed for significant differences between patients with and without respiratory insufficiency. Ultrasound was performed on all patients with a prolonged ICU LOS. Data was analyzed for significant differences between patient groups. Results: No significant differences were found on chest radiograph measurements in patients with and without prolonged ICU LOS. Ultrasound measurements showed no significant differences between patients with and without respiratory insufficiency. Diaphragm variables showed significant differences in favor of healthy subjects as found in the literature. No correlation was found between chest radiograph and ultrasound variables. Conclusion: Our objective to establish a simple method to predict a prolonged ICU LOS in patients with respiratory insufficiency using chest radiograph and ultrasound measurements has not been achieved.
