Clinical Trial Summary

The aim of this study was to compare fetal lung elastography (FAE) values between groups with and without Respiratory Distress Syndrome (RDS) in preterm neonates and to evaluate the potential of FAE to predict the risk of developing RDS.

Description:

The evaluate the potential of fetal lung elastography as a non-invasive method to predict and treatment respiratory complications in preterm neonates. FAE is an imaging method that measures the elasticity properties of fetal lung tissue using ultrasound technology. This method can be helpful in providing information about the development and respiratory function of the fetal lungs. The advantages of FAE are: It is a non-invasive method: FAE is performed using ultrasound technology and has no known maternal or fetal harm. It stands as a potentially safe method compared to current invasive tests. It is cost-effective and easy to perform: FAE is a procedure performed using existing ultrasound equipment at no separate cost. Therefore, it can be easily implemented and repeated in clinical settings. Fast results: FAE provides fast results by acquiring images in real time. This indicates that FAE can be a valuable diagnostic tool in emergency situations or when rapid decision-making is required. A potential predictive tool: The results of this study may indicate that FAE values are a potential tool for predicting the risk of developing RDS. This could be an important step to develop early diagnosis and treatment strategies to improve the respiratory health of preterm newborns.
