About this study

Official title: A Study Evaluating Use of the Proximal Humerus Intraosseous Vascular Access Site for Anesthesia Patient Positioning

This will be a prospective, non-controlled study using healthy adult volunteers as subjects receiving bilateral proximal humerus intraosseous (IO) vascular access to evaluate the insertion technique and IO infusion flow rates.

Read the detailed description

When using IO access in the perioperative and OR settings, abduction of the arms to the shoulder level prevents use of the traditional proximal humerus insertion site due to the rotation of the humeral head under the acromion process. An alternate proximal humerus IO insertion technique has been developed to meet the needs of anesthesia patient positioning that uses a slightly more distal insertion site and a superior angle of insertion. However infusion flow rate in the proximal humerus using the anesthesia technique has not been measured. This study is needed to evaluate the anesthesia proximal humerus IO insertion technique to determine if the IO infusion flow rates remain unchanged by the alternate method.

What participants receive

  • intraosseous vascular access in the proximal humerusDevice

    Also called EZ-IO, Proximal Humerus intraosseous access, IO access, proximal humerus IO access

    The arm receiving the Intraosseous (IO) needle is positioned with the arm abducted to shoulder level (in position required for surgery), with the arm rotated inward, into the optimal position, with the palms faced down. Deeply palpate the humerus until the junction of the humeral shaft and the humeral head, the surgical neck is identified; the insertion site is in the surgical neck. With the 45mm IO needle placed perpendicular to the plane of the skin, the IO needle is inserted into the surgical neck using a slightly superior angle of insertion and the needle is inserted to the hub. The stylet will be removed and a primed EZ-Connect will be attached to the catheter hub.

What is being measured

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

  1. Intraosseous Infusion Flow Rate

    the mean infusion flow rate reported in milliliters per hour (mL/hr) obtained at each tested infusion pressure.

    Measured: Day 1, within 30 minutes of establishing proximal humerus intraosseous (IO) vascular access

Secondary outcomes (2)
  1. Success Rate of Obtaining Laboratory Results for Both Intraosseous and Peripheral Venous Specimens

    Number of Participants with Laboratory Results Successfully Obtained from both intraosseous (IO) and peripheral venous blood specimens. Success was determined if the point-of-care laboratory analysis system provided laboratory results values for both IO and Peripheral Venous specimens. It was deemed unsuccessful if the point-of-care system provided no laboratory results values and/or noted an error for at least one specimen. An intraosseous blood specimen and a peripheral venous blood specimen were collected from each subject.

    Measured: Day 1 within 30 minutes after establishing proximal humerus IO vascular access and peripheral venous access

  2. Time Measured in Seconds for Fluid Delivery From the Proximal Humerus Intraosseous (IO) Site to the Heart

    time measured in seconds for fluid delivery from the proximal humerus intraosseous site to the heart, using visualization of contrast injection under fluoroscopy.

    Measured: Day 1 within 1 hour after establishing proximal humerus intraosseous vascular access

Questions about this trial

What is this clinical trial studying?

A study testing intraosseous vascular access in the proximal humerus and EZ-IO in people with Intraosseous Vascular Access, run by Vidacare Corporation 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 4 inclusion and 18 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 17 Apr 2026. 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?

Yes. Results are posted in the registry (first posted 17 Apr 2026). 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?

Intraosseous Infusion Flow Rate (time frame: Day 1, within 30 minutes of establishing proximal humerus intraosseous (IO) vascular access). 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 17 Apr 2026.
