Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The study population will be patients who undergo any form of surgery, where he/she is mechanically ventilated, preferably cases that require arterial line placement, use of cardiac output measurement, and where fluid administration will occur perioperatively.

Who may be able to join

  • 18 years of age or older
  • Undergo any type of surgeries under general anesthesia in UCI Medical Center
  • Mechanically ventilated during surgery
  • Arterial line placement is preferred but not required

  • Pregnant women
  • Refused to sign the consent and HIPAA forms
  • Receive vasoactive medication prior to surgery
  • Has these conditions: hypotension, hypothyroidism, moderate or poorly controlled hypertension, chronic poorly-controlled diabetes, heart failure patients, and patients with active airway flow obstruction, left ventricular dysfunction, intra-cardiac shunts, right ventricular dysfunction, atrial fibrillation, arrhythmias
  • patients with surgeries at or around site of sensor placement
  • Subject has skin abnormalities affecting the digits such as psoriasis, eczema, angioma, scar tissue, burn, fungal infection, substantial skin breakdown, nail polish or acrylic nails that would prevent monitoring of SpO2 levels during the study

About this study

Official title: Comparing PVI Measurements at Different Sensing Locations

The purpose of this study is to assess the suitability of the ear and forehead as a better site for measure of fluid responsiveness.

Read the detailed description

The aim of this study is to compare Pleth Variability Index (PVI) measurements at different sensor locations in respect to signal quality, sensor fit to site location and fluid responsiveness. PVI will be measured at 3 different sensor sites: the fingers, ear lobes and forehead. The ability to predict fluid responsiveness will be analyzed using cardiac output as the reference value.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. PVI measurement of fluid responsiveness

    The primary outcome is to test the ability of PVI recorded at the finger and at the ear to predict fluid responsiveness.

    Measured: Intra-operative

Questions about this trial

What is this clinical trial studying?

An observational study of Fluid Imbalance, run by University of California, Irvine at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PVI measurement of fluid responsiveness (time frame: Intra-operative). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02124551, which also lists 7 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Mar 2021; AzTrials last refreshed its copy on 31 Oct 2026.
