NCT02376361

Brief Summary

The purpose of the study is to learn if monitoring dialysis access blood flow during dialysis treatment with a transonic machine (an ultrasound technique) will prevent (or reduce) the development of dialysis access thrombosis (clotting). Investigators would like to study if monitoring with a specific technique called ultrasound dilution technique can help prevent problems with access when compared to what is the current standard of care for patients.

Study Arms (2)

Surveillance Group

ACTIVE COMPARATOR

Monthly blood flow surveillance by ultrasound dilution technique and standard of care.

Device: Transonic

Control Group

NO INTERVENTION

Control group will receive standard monitoring (standard care).

Interventions

TransonicDEVICE

Access recirculation, access flow would be determined using the ultrasound dilution technique (Transonic system). 1. Within 90 min of the beginning of HD session HD03 sensors are clamped HD tubing lines 2. Recirculation, access flow will be performed according to HD03 Manual. 3. Post intervention evaluation is as per each arm follow up unless other follow up deemed necessary by the interventionalist.

Surveillance Group

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Chronic hemodialysis patients undergoing dialysis therapy via an upper extremity arteriovenous access (arteriovenous fistula or an arteriovenous graft) will be enrolled to have monthly surveillance flow measurement using Transonic system or physical examination of the arteriovenous access by qualified person at least once a month for a period of 2 years.

You may not qualify if:

  • Patients requiring surgical intervention on the arteriovenous access.
  • History of access thrombosis (one or more access thrombosis of the current arteriovenous access).
  • Patients with signs of access infection.
  • Patients with a malignancy.
  • Patients with life expectancy of less than six months.
  • Unable to understand the study.
  • Unable to sign the consent form.
  • Patients with psychiatric disorder.
  • Age less than 18 or greater than 80 years.
  • Adults unable to consent
  • Individuals who are not yet adults (infants, children, teenagers)
  • Pregnant women
  • Prisoners
