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.

Condition Intervention Phase
Prematurity of Fetus Patent Ductus Arteriosus Drug: Indomethacin Procedure: Surgical Ligation Drug: Ibuprofen Phase 4

Study Type: Observational
Study Design: Observational Model: Cohort

Primary Outcome Measures:
  • Change of cerebral tissue oxygen saturation during treatment for patent ductus arteriosus [ Time Frame: from 10 minutes before start of infusion until 4 hours after end of transfusion ]

Enrollment: 35
Study Start Date: April 2011
Study Completion Date: March 2016
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Infants treated with Indomethacin
Drug: Indomethacin
3 doses of 0,2mg/kg every 12h (first week of life) or every 8h (after first week of life)
Infants treated with Ibuprofen
Drug: Ibuprofen
3 doses every 24h; first dose 10mg/kg, second and third dose 5mg/kg
Infants undergoing surgical ligation
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.
