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

Who may be able to join

  • Adult patients undergoing major surgeries associated with possibility of significant blood loss (e.g. such that blood is cross-matched and available before the start of the case as per hospital routine practice) under general anesthesia.
  • At least one finger available and accessible for performing non-invasive hemoglobin monitoring.

Who cannot join

  • Patient 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 the proper fit and application of the sensors
  • Procedures performed using robotics surgery
  • Any patients with a known hemoglobinopathy

About this study

Official title: Evaluation of Impacts of Continuous Non-Invasive Intra-Operative Hemoglobin and PVI Monitoring on Intra-Operative and Post-Surgical Clinical Outcomes

The study evaluates the use of noninvasive hemoglobin with In Vivo feature and PVi monitoring using pulse-oximetry based technologies and their effect on the management of transfusion and infusion decisions and clinical outcomes for the surgical patient.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • In vivo SpHb and PVi MonitoringDevice

    Pulse oximeter finger sensor that simultaneously monitors noninvasive hemoglobin (SpHb) and pleth variability index (PVi)

Study groups in NCT02986789
Study groupRoleWhat they receive
Control GroupNo interventionClinicians will be performing blood transfusions using hospital standard of care procedures.
Evaluation GroupExperimentalClinicians will be guiding blood transfusions using SpHb with In vivo feature as a trigger for laboratory blood draws and PVi to inform fluid administration decisions in addition to hospital standard of care procedures.
Receives: Device: In vivo SpHb and PVi Monitoring

What is being measured

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

  1. Average Volume of Allogenic RBC Transfused Intra-operatively

    Reduction in overall allogenic transfusion is defined as the decrease in volume of transfusion of the intervention group relative to control group, intra-operatively.

    Measured: Approximately 6-8 hours

Questions about this trial

What is this clinical trial studying?

A study testing In vivo SpHb and PVi Monitoring in people with Surgery, run by Masimo Corporation.

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 2 inclusion and 15 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: stopped early, as of the sponsor's last update on 18 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 5 Jan 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Average Volume of Allogenic RBC Transfused Intra-operatively (time frame: Approximately 6-8 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Jun 2026.
