Passive Leg Raise Induced Stroke Volume Changes in Elderly Prior to Elective Surgery Measured by LiDCOplusTM

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02977390

Brief Summary:
This is a pilot study to investigate whether patients at advanced age are fluid responders via a reversible fluid challenge, the passive leg raise test. This will be measured with a non-invasive cardiac output monitor, the LiDCO (LiDCO Hemodynamic monitoring) .

Condition or disease Intervention/treatment Phase
Stroke Volume Cardiovascular System Fluid Therapy Other: Passive leg raise Not Applicable

Detailed Description:
The intervention is as simple as a passive leg raise with measurement of effect on Stroke volume.

Primary Purpose: Diagnostic
Official Title: Passive Leg Raise Induced Stroke Volume Changes in Elderly Prior to Elective Surgery Measured by LiDCOplusTM to Guide Fluid Therapy
Study Start Date : October 2013
Actual Primary Completion Date : January 2015
Actual Study Completion Date : January 2015

Arm Intervention/treatment
Passive Leg Raise (PLR)

The patient is placed in a 45 degree recumbent position. Stroke volume is measured in ml.

Intervention:The patient is placed horizontal and the legs are passively raised to 45 degrees.

Measurement:The effect of the PLR on Stroke Volume is measured. Thereafter the patient is repositioned to the initial position and Stroke Volume is measured again.

Other: Passive leg raise
By tilting the patient's bed from sitting 45 degrees to supine with legs tilted up 45 degrees we recruit the blood volume in the legs and can measure a reversible fluid challenge on stroke volume.

Primary Outcome Measures :
  1. Assess passive leg raise responsiveness in spontaneously breathing aged patients. [ Time Frame: Within 1 minute of the intervention ]
    Stroke volume changes in ml and as per cent change compared to baseline

Secondary Outcome Measures :
  1. Investigate whether there is an association between a positive response to passive leg raise on stroke volume and post spinal anesthesia. [ Time Frame: 30 minutes ]
    Post spinal bloodpressure per cent change or 30 mmHg decrease
