Primary Outcome Measures:
  • Change of cerebral tissue oxygen saturation during treatment for patent ductus arteriosus [ Designated as safety issue: No ]

Estimated Enrollment: 30
Study Start Date: April 2011
Estimated Study Completion Date: April 2013
Estimated Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Infants with hemodynamically relevant patent ductus arteriosus Drug: Indomethacin
3 doses of 0,2mg/kg every 12h (first week of life) or every 8h (after first week of life)
Procedure: Surgical Ligation
In nonresponders to medical treatment with persistent hemodynamically relevant patent ductus arteriosus surgical ligation is performed.

Detailed 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.
