Volume Deficit Prior to Surgery

This study has been completed.
Information provided by:
Rigshospitalet, Denmark Identifier:
First received: September 22, 2006
Last updated: August 5, 2009
Last verified: August 2009

It is the purpose of the researchers to identify the variation in intravascular deficits which can have relevance in high risk patients for minor and medium sized surgery.

The investigators will also estimate fluid deficit in healthy, non-fasting subjects for comparison.

Condition Phase
Hypovolemia Surgery Phase 4

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Estimation of Volume Deficit in Patients Prior to Surgery

Enrollment: 4
Study Start Date: October 2006
Study Completion Date: August 2007
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Detailed Description:

Intravascular volume optimization has shown to improve outcome after surgery. In minor and medium surgery , however, the preoperative volume deficit has not been estimated with functional parameters. Patient scheduled for minor surgery are included. After the patient is anesthetized the intravascular volume is optimized by stroke volume maximization by colloid boluses. Stroke volume is obtained by esophageal Doppler technique which is a minimally invasive method.

The volume estimated for optimization is considered as the functional volume deficit.

In the healthy subjects the probe will be placed in the awake subject. A standardized meal and fluid intake secures that the subjects are in a non-fasting state.
