Clinical Trial Summary

Electric Impedance Tomography (EIT) is a lung monitoring technique based on the injection of small currents and voltage measurements using electrodes on the skin surface generating cross-sectional images representing impedance change in a slice of the thorax. It is a real time, radiation free, non-invasive and portable. Neonatal respiratory distress syndrome (RDS) is a respiratory disorder resulting from immaturity of the lung structure and lack of surfactant. It is one the most common conditions in premature infants. Many of these infants require either invasive or non-invasive respiratory support. The goal of the study is to investigate the dynamic changes in pulmonary aeration during assisted breathing in very low birthweight preterm infants using pulmonary electrical impedance tomography. Currently most widely used methods to assess respiratory lung function are either invasive and/or indirect (ABG, pulse oximetry, transcutaneous pCO2 measurement), lacks temporal resolution (lung ultrasound) or emit ionizing radiation (CT). EIT provides information on regional lung aeration without the aforementioned shortcomings.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Predict criteria and preconditions for the successful extubation using electrical impedance tomography	Same as primary outcome	3 days
Primary	To evaluate the lung aeration properties of very low birth weight neonates using different respiratory therapy methods and regimens.	Lung aeration and ventilation will be assessed with EIT. Several methods will be used and compared, based on pixel information of lung aeration, and pressure-volume characteristics, regional ventilation distribution and etc.	1 - 5 days.
Secondary	To evaluate the characteristics of lung aeration during routine nursing care in preterm very low birthweight infants receiving respiratory support.	Same as primary outcome.	1 - 5 days.
Secondary	To compare lung aeration and regional ventilation distribution between two non-invasive respiratory therapies, constant positive pressure and high-flow nasal cannula in very low birthweight neonates.	Same as primary outcome	1 - 5 days.
