Summary

A prospective cohort study aims to evaluate the predictive value of thoracic fluid content measured by electric bioimpedance for detecting the need for surfactant administration or positive pressure ventilation requirement; whether invasive or non-invasive; in preterm neonates with respiratory distress and to compare it to lung ultrasound.

Detailed description

Electrical cardiometry (bioimpedance) is an impedance-based method that has been recently introduced for continuous noninvasive hemodynamic monitoring for cardiac output (CO) and TFC in both term and preterm infants. TFC is the sum of the total fluid volume found in the chest cavity; it is measured as the baseline resistance (bioimpedance) to the passage of a small electrical current through all chest tissues. Larger TFC indicates a higher total thoracic fluid volume. TFC measurement has been correlated with heart failure symptoms, net fluid balance, and chest radiographic findings of abnormal pulmonary fluid content in adults. Lung ultrasound (LUS) is a reliable technique for physicians to complement physical examination findings and has emerged as an alternative option to overcome the limitations of chest x rays (CXRs). Moreover, LUS shows better diagnostic accuracy than CXR in some critical conditions and has been successfully adapted in NICUs for the diagnosis of several diseases. We thought that TFC monitoring may be able to predict the need for surfactant administration or positive pressure ventilation requirement; whether invasive or non-invasive; in preterm neonates with respiratory distress comparable to LUS.
