Clinical Trial Summary

The purpose of this study is to examine the influence medical or surgical treatment for patent ductus arteriosus in preterm infants on cerebral and renal tissue oxygenation and on cardiac output.


Clinical Trial Description

In this observational trial the investigators want to examine whether clinical or echocardiographic parameters of patent ductus arteriosus are related to

- cerebral tissue oxygen saturation, total hemoglobin, fractional tissue oxygen extraction and HbD

- renal tissue oxygen saturation, total hemoglobin, fractional tissue oxygen extraction and HbD

as measured by near infrared spectroscopy

and to

- stroke volume

- cardiac output

as measured by electrical cardiometry.

The investigators want to examine the impact of surgical and medical treatment for patent ductus on these parameters. The investigators want to compare the change of these parameters between responders to medical treatment and nonresponders. ;
