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

2016-12-01 16:08:22 | BioPortfolio

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) .

Description

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

Study Design

Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic

Conditions

Stroke Volume

Intervention

Passive leg raise

Location

Karolinska University Hospital
Huddinge
Sweden

Cardiac stroke volume variability measured non-invasively by three methods for detection of central hypovolemia in healthy humans.

Hypovolemia decreases preload and cardiac stroke volume. Cardiac stroke volume (SV) and its variability (cardiac stroke volume variability, SVV) have been proposed as clinical tools for detection of a...

Medical and Biotech [MESH] Definitions

The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).

The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.

The amount of BLOOD pumped out of the HEART per beat not to be confused with cardiac output (volume/time).

A type of impedance plethysmography in which bioelectrical impedance is measured between electrodes positioned around the neck and around the lower thorax. It is used principally to calculate stroke volume and cardiac volume, but it is also related to myocardial contractility, thoracic fluid content, and circulation to the extremities.

The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.
