The purpose of the study is to examine the relevance of biochemical markers (specific pulmonary and cardiac markers and markers of endogenous stress) in the process of weaning in patients with artificial ventilation.

Duration of Weaning

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: The Relevance of Biochemical Markers in the Process of Weaning

Further study details as provided by Heidelberg University:

Primary Outcome Measures:
  • success of weaning [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 30days ]
    primary outcome measure is the success of weaning during hospital stay. Duration of hospital stay is estimated between 1-60days, in average 30days. Criteria is spontaneous breathing.

Secondary Outcome Measures:
  • follow up [ Time Frame: 12 months ]
    Follow up is done after 12 months to check major adverse cardiac or pulmonary events (death, myocardial infarction, re-hospitalisation)

Biospecimen Retention:   Samples With DNA
routine blood parameters

Estimated Enrollment: 100
Study Start Date: April 2011
Estimated Study Completion Date: April 2013
Estimated Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
weaning patients

Detailed Description:
Artificially ventilated patients on our intensive care unit will be monitored if specific biomarkers have a relevance in risk stratification, optimizing therapy, outcome and success in the process of weaning. Therefore, consecutively, specific blood parameters will be taken at time of intubation,day 1 of weaning and extubation.
