September 14, 2026 updated by: HemoSonics LLC
This study will determine reference range intervals for the parameters reported by the Quantra System with the QPlus Cartridge in pediatric patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The hemostatic profile of an infant is different than that of an adult and changes with age. Most differences occur within the first 6 months of age, with coagulation function similar to that of an adult within the first year of life. To assess the clinical utility of the Quantra System in pediatric patients that are bleeding or at risk for bleeding, it is important to understand the normal reference intervals for the parameters reported by the QPlus Cartridge in normal, healthy pediatric patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

N/A

Sampling Method

Non-Probability Sample

Study Population

Children, age birth to <18 years of age, scheduled for a procedure requiring anesthesia in which vascular access would routinely be placed.

Description

Inclusion Criteria:

  • Subject is <18 years of age
  • Corrected gestational age ≥ 37weeks
  • Subject is scheduled for an elective surgery, non-surgical intervention or diagnostic procedure requiring anesthesia and vascular access with an ASA score ≤3.
  • Subject's parent or guardian has signed an informed consent form. If required, subject has signed an assent form.

Exclusion Criteria:

  • Subject is hospitalized in the Pediatric Intensive Care Unit
  • Subject requires Extracorporeal Membrane Oxygenation (ECMO)
  • Subject has had an infection within 7 days of the scheduled procedure
  • Subject has an active coagulation disorder (bleeding or thrombosis)
  • For subjects that have a hemoglobin measurement within 24 hours of the scheduled procedure, hemoglobin is <8g/dL or >16g/dL
  • Subject has a baseline oxygen saturation <92%

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 15, 2027

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
