ClinicalTrials.gov Identifier:
NCT00447200
First received: March 13, 2007
Last updated: October 12, 2007
Last verified: October 2007
  Purpose

We would like to investigate the natural variation in the strokevolume of the heart. At the same time we would like to find out the minimal number of heart cycles necessary to discover a 10% increase in strokevolume, after a fluid bolus of 200ml Voluven, when using Esophageal Doppler.


Condition Intervention
Stroke Volume Variation
Procedure: Esophagus Doppler monitoring
Procedure: Fluid optimization

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Study of the Natural Variation in Strokevolume, and Investigation in the Number of Cycles Necessary to Find a 10% Strokevolume Variation Using Esophageal Doppler

Further study details as provided by Rigshospitalet, Denmark:

Primary Outcome Measures:
  • Strokevolume variation before fluid optimization
  • Strokevolume variation after fluid optimization
  • Number of cycles needed in order to detect a 10% strokevolume increase after fluid bolus of 200ml Voluven.

Enrollment: 20
Study Start Date: March 2007
Study Completion Date: August 2007
Detailed Description:

We would like to investigate the natural variation in the strokevolume(SV) of the heart. At the same time we would like to find out the minimal number of heart cycles necessary to discover a 10% increase in SV, after a fluid bolus of 200ml Voluven, when using Esophageal Doppler.

Also we will compare the variation in SV both before and after the patients have been fluid optimized, using an algorithm of 10% increase in SV in order to receive another fluid bolus. The equipment used, will be the CardioQ from Deltex medical.
