About this study

Official title: Local Warming Technique for Arterial Cannulation in Adult Patients Under Heart Surgery-A Randomized Controlled Trial

Based on the fact that arterial vasodilation can be advantageous for endovascular catheterization and that an increase in body temperature can cause vasodilation by activating the cholinergic active vasodilator system, this study was planned to observe whether there was a significant change in the diameter of artery through ultrasound and to confirm the effectiveness of heating in the traditional palpation technique and the US-guided technique after local warming of the insertion site of arterial catheter in adult patients undergoing cardiac surgery.

Read the detailed description

Arterial cannulation is one of the important clinical techniques commonly used for real-time monitoring of blood pressure changes or when repeated blood tests are required. However, complications such as bleeding, hematoma, and vascular occlusion may occur if the operator has little or no experience in the procedure, or if arterial cannulation is not easy due to the patient's underlying disease and systemic factors. This situation prolongs the anesthesia induction time and may cause great harm to the patient in cases with a high bleeding tendency, such as in cardiac surgery. Various studies have reported various arterial cannulation techniques so far, and there have been many advances in arterial cannulation techniques due to the general use of ultrasound (hereafter US). However, there is still a risk of complications due to inexperience in the use of US or poor vascular status of the patient.

What participants receive

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

  • warming to increase local skin (puncture site) temperatureProcedure or surgery

    According to the group of participants, investigator applies the warmer to the hands and wrists of the participants, makes a local temperature of 40℃ gradually, and maintains it for about 10 minutes in warming group (which is divided in to warming-palpation (WP) and warming-US (WU) group).

What is being measured

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

  1. changes of the diameter of the artery

    Investigator measures where there is a significant increase in the diameter of the artery due to warming using US.

    Measured: from time point of warming to success of arterial cannulation (the day of surgery, up to 1hour)

  2. changes of the cross-sectional area of the artery

    Investigator measures where there is a significant increase in the cross-sectional area of the artery due to warming using US.

    Measured: from time point of warming to success of arterial cannulation (the day of surgery, up to 1hour)

  3. Success rate of first trial for arterial cannulation

    Investigator measures success rate of first trial for arterial cannulation.

    Measured: from time point of warming to success of arterial cannulation (the day of surgery, up to 1hour)

Secondary outcomes (1)
  1. Complications related with arterial cannulation

    Investigator measures where there are complications such as hematoma, vasopasm, and ischemia.

    Measured: from time point of warming to success of arterial cannulation (the day of surgery, up to 1hour)

Questions about this trial

What is this clinical trial studying?

A study testing warming to increase local skin (puncture site) temperature in people with Cardiac Disease Which Should be Treated by Surgery, run by Pusan National University Yangsan Hospital at 1 site in South Korea.

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 1 inclusion and 3 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 12 Aug 2024. 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 South Korea. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

changes of the diameter of the artery (time frame: from time point of warming to success of arterial cannulation (the day of surgery, up to 1hour)). The study lists 3 primary outcomes in all. 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 NCT04969692, 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 12 Aug 2024.
