Impact of Heparin on the Need for Mechanical Ventilation in Neonates

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified September 2006 by University Medicine Greifswald.
Recruitment status was:  Recruiting

University Medicine Greifswald Identifier:
First received: September 12, 2005
Last updated: October 22, 2007
Last verified: September 2006
This study is designed to test an incidental finding of a previous trial in which post hoc analysis showed that the rate of intensive care newborns requiring mechanical ventilation was lower in the group receiving heparin with the continuous infusion as compared to the placebo group.

Condition Intervention Phase

Further study details as provided by University Medicine Greifswald:

Primary Outcome Measures:
  • percentage of neonates requiring mechanical ventilation

Secondary Outcome Measures:
  • duration of dependency on mechanical ventilation
  • major bleeding
  • heparin induced thrombocytopenia
  • anti PF4/heparin antibodies

Estimated Enrollment: 270
Study Start Date: December 2003
Estimated Study Completion Date: March 2007
Detailed Description:

Title: Randomized double blind trial comparing heparin and placebo as additives to continuous infusion in intensive care neonates for prevention of mechanical ventilation

Primary endpoint: Percentage of neonates requiring mechanical ventilation in both groups

Secondary endpoints: Duration of dependency on mechanical ventilation; major bleedings, incidence of heparin-induced thrombocytopenia and of anti-platelet factor 4/heparin antibodies
