About this study

Official title: Effect of Dumbbell Exercise on Arteriovenous Fistula in Patients With Hemodialysis:A Prospective Randomized,Controlled Trial

Isometric exercise has been shown to increase the diameter and the blood flow rate of forearm veins.At present, more studies focus on the perioperative period to promote the maturation of arteriovenous fistula(AVF), while there are few reports on functional maintenance measures for the patients with maintenance hemodialysis.This study aims to explore the effect of dumbbell exercise on AVF,and evaluate whether patients can carry a 6-pound item with the fistula limb in a reasonable way.

Read the detailed description

Autologous arteriovenous fistula (AVF) is the preferred vascular access for maintenance hemodialysis patients. It is estimated that AVF accounts for 85-90% of the permanent vascular access in Chinese hemodialysis patients. With the prolongation of dialysis time, aging, and the increase of diabetes incidence, the complications of AVF are more and more common, which affect the lifetime of AVF. Therefore,self-maintenance of AVF is essential. Among them, exercise should be used throughout the entire process of AVF use for the reason that it is economical, easy to operate, and highly repeatable.The most common isometric exercise is handgrip exercise. However, there are some deficiencies in this exercise, such as lack of quantitative standards and burnout of repeated actions. As a result, this study uses quantitative dumbbells as a training tool to explore the effect of dumbbell exercise on the maintenance of AVF, and further evaluates and breaks the nursing routine of "no lifting weights" of fistula limb.

What participants receive

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

  • The handgrip exerciseBehavioural

    The control group was given routine dialysis treatment and daily handgrip exercise .Patients are asked to squeeze a rubber ring 30 times per min for altogether 20 minutes on non-dialysis days.The 20-minute exercise can be divided into 3 parts according to individual circumstances.

  • The dumbbell exerciseBehavioural

    The experimental group was given routine dialysis treatment and daily dumbbell exercise .Patients are asked to hold 6-pound dumbbells to exercise 30 times per min for altogether 20 minutes on non-dialysis days.The 20-minute exercise can be divided into 3 parts according to individual circumstances.

What is being measured

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

  1. Changes in blood flow of AVF draining vein

    The blood flow measurement was repeated three times at a location 5 cm proximal to the anastomosis in the draining vein by Doppler ultrasound.

    Measured: from Baseline to 3 months

Secondary outcomes (5)
  1. Changes in diameter of AVF draining vein

    The diameter measurement was repeated three times at a location 5 cm proximal to the anastomosis in the draining vein by Doppler ultrasound.

    Measured: from Baseline to 3 months

  2. The ratio of pre-pump arterial pressure and blood flow

    The ratio of pre-pump arterial pressure and blood flow during the hemodialysis treatment.

    Measured: from Baseline to 3 months

  3. Adverse event

    The incidence of adverse event(puncture site hematoma,hemorrhage,aneurysm,heart failure,joint sprain,falls,anastomotic rupture,etc).

    Measured: from Baseline to 3 months

  4. Changes in blood flow of AVF proximal artery

    The blood flow measurement was repeated three times at a location 5 cm proximal to the anastomosis in the proximal artery by Doppler ultrasound.

    Measured: from Baseline to 3 months

  5. Changes in blood flow of brachial artery

    The blood flow measurement was repeated three times at a location 2 cm above the elbow in the brachial artery by Doppler ultrasound.

    Measured: from Baseline to 3 months

Questions about this trial

What is this clinical trial studying?

A study testing The handgrip exercise and The dumbbell exercise in people with Arteriovenous Fistula, run by Guangdong Provincial People's Hospital at 1 site in China.

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 3 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 15 Nov 2018. 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 China. 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in blood flow of AVF draining vein (time frame: from Baseline to 3 months). 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 NCT03741985, which also lists 1 linked publication.

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 15 Nov 2018.
