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

Not Applicable
Completed
Conditions
Cardiovascular System
Fluid Therapy
Stroke Volume
Interventions
Other: Passive leg raise
Registration Number
NCT02977390
Lead Sponsor
Karolinska Institutet
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) .

Detailed Description

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

GroupInterventionDescription
Passive Leg Raise (PLR)Passive leg raiseThe 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.
Primary Outcome Measures
NameTimeMethod
Assess passive leg raise responsiveness in spontaneously breathing aged patients.Within 1 minute of the intervention

Stroke volume changes in ml and as per cent change compared to baseline

Secondary Outcome Measures
NameTimeMethod
Investigate whether there is an association between a positive response to passive leg raise on stroke volume and post spinal anesthesia.30 minutes

Post spinal bloodpressure per cent change or 30 mmHg decrease
