About

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) .

Full description

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

Enrollment: 10 patients

Sex: All

Ages: 80+ years old

Volunteers: Accepts 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.

Trial design

Primary purpose: Diagnostic

Allocation: N/A

Interventional model: Single Group Assignment

Masking: None (Open label)

10 participants in 1 patient group

Passive Leg Raise (PLR)

Other group

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.

Treatment:

Other: Passive leg raise
