About this trial

This is an interventional diagnostic trial for Stroke Volume

Eligibility Criteria

80 Years - undefined (Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • patients ≥80 years of age, undergoing elective urologic surgical procedure

Exclusion Criteria:

  • age <80 years, severe aortic insufficiency, first case of the day on the operation program, unavailability of research personnel and contraindication to Lithium.

Sites / Locations

  • Karolinska University Hospital

Arms of the Study

Arm 1

Arm Type

Other

Arm Label

Passive Leg Raise (PLR)

Arm Description

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.

Outcomes

Primary Outcome Measures

Assess passive leg raise responsiveness in spontaneously breathing aged patients.
Stroke volume changes in ml and as per cent change compared to baseline

Secondary Outcome Measures

Investigate whether there is an association between a positive response to passive leg raise on stroke volume and post spinal anesthesia.
Post spinal bloodpressure per cent change or 30 mmHg decrease

5. Study Description

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.

Intervention Type
Other
Intervention Name(s)
Passive leg raise
Intervention Description
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 Measure Information:
Title
Assess passive leg raise responsiveness in spontaneously breathing aged patients.
Description
Stroke volume changes in ml and as per cent change compared to baseline
Time Frame
Within 1 minute of the intervention
Secondary Outcome Measure Information:
Title
Investigate whether there is an association between a positive response to passive leg raise on stroke volume and post spinal anesthesia.
Description
Post spinal bloodpressure per cent change or 30 mmHg decrease
Time Frame
30 minutes
