About this study

Official title: Randomized Comparison of Radiation Exposure in Coronary Angiography Between Right Conventional and Left Distal Radial Artery Approach: The DOSE Trial

Randomized comparison of radiation exposure in coronary angiography between right conventional and left distal radial artery approach

Read the detailed description

The left snuffbox approach is expected to be easier to perform because of less severe tortuosity of the clavicle artery. However, clinical validation of the snuffbox approach was not completed compared with the conventional radial approach. Especially, there is no clinical data on the comparison of the radiation dose in both approaches. To date, there have been some studies on the radiation dose between the left and right radial artery and femoral artery puncture site, but no studies have been conducted on the left snuffbox approach.

The purpose of this study was to compare the radiation doses of the two interventional radiologists by randomly assigning coronary angiography to the left snuffbox approach and right conventional radial approach.

What participants receive

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

  • artery puncture and coronary angiographyProcedure or surgery

    We will perform coronary angiography through a Judkins 5 French diagnostic catheter and will take a basic view. At the end of the examination, the radial sheath is removed and the right conventional radial approach is performed for about 4 hours and the left snuffbox approach for about 2 hours using the compressive bandage method. The hemostatic device will use ez ClotRadial® (SOYEON medical Co., Ltd., Wonju, Korea).

Study groups in NCT04023838
Study groupRoleWhat they receive
Right conventional radial approachPlacebo comparatorAfter local anesthesia on right wrist area with lidocaine hydrochloride using a 26 gauge needle, the puncture is performed using a 20 gauge needle with the through-and-through puncture technique or a 21 gauge open needle with anterior wall puncture technique. After the successful puncture, 0.025-inch straight wire or 0.018-inch hair wire are inserted, followed by insertion of the 5Fr. radial sheath (Prelude® Radial; Merit medical, UT, USA or Radifocus® Introducer II or Glidesheath Slender®; Terumo Corporation, Tokyo, Japan).
Receives: Procedure: artery puncture and coronary angiography
Left distal radial approachActive comparatorAfter local anesthesia on left anatomical snuffbox area with lidocaine hydrochloride using a 26 gauge needle, the puncture is performed using a 20 gauge needle with the through-and-through puncture technique or a 21 gauge open needle with anterior wall puncture technique. After the successful puncture, 0.025-inch straight wire or 0.018-inch hair wire are inserted, followed by insertion of the 5Fr. radial sheath (Prelude® Radial; Merit medical, UT, USA or Radifocus® Introducer II or Glidesheath Slender®; Terumo Corporation, Tokyo, Japan).

What is being measured

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

  1. Radiation dose of the operator (µSv)

    Radiation dose (µSv) of the operator's head, hand, and body will be compared between right conventional radial artery approach and left snuffbox approach group.

    Measured: Through procedure completion, up to 6 hours

Secondary outcomes (6)
  1. Fluoroscopy time for coronary angiography (second)

    Fluoroscopy time (second) will be compared between two groups during coronary angiography.

    Measured: Through procedure completion, up to 6 hours

  2. Dose-area product (mGy*cm2)

    Dose-area product (DAP) (mGy*cm2) will be compared between two groups during coronary angiography.

    Measured: Through procedure completion, up to 6 hours

  3. Success rate of radial puncture (%)

    Successful introduction of sheath (%)

    Measured: Through procedure completion, up to 6 hours

  4. Cannulation time (second)

    Time from local anesthesia to sheath cannulation (second)

    Measured: Through procedure completion, up to 6 hours

  5. Hemostasis duration (minute)

    Hemostasis (minute) is obtained by compressive bandage with ez ClotRadial® (SOYEON medical Co., Ltd., Wonju, Korea)

    Measured: During hospitalization, up to 1 month

  6. Puncture site complication after hemostasis

    Evaluation of puncture-site bleeding complication using EASY criteria

    Measured: During hospitalization, up to 1 month

Questions about this trial

What is this clinical trial studying?

A study testing artery puncture and coronary angiography in people with Radiation Exposure and Vascular Access Complication, run by Chonnam National University Hospital.

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 8 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 18 Jul 2019. 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. 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?

Contact Yongcheol Kim, MD (+82-10-5808-4029, Dr.YongcheolKim@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Radiation dose of the operator (µSv) (time frame: Through procedure completion, up to 6 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 Jul 2019.
