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

• 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.

Primary Outcome Measures

Name	Time	Method
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

Name	Time	Method
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
