About this study

Official title: Ultrasound Guided Ulnar Versus Radial Artery Cannulation in Pediatrics Undergoing Major Non Cardiac Surgery: Double Blinded Randomized Controlled Study

This study aims to assess the safety and efficacy of ulnar artery cannulation compared to radial artery cannulation in pediatrics undergoing major non cardiac procedures.

Read the detailed description

The study is a double blinded randomized controlled trial that will be conducted at Abu Al Reesh Children's Hospital, Faculty of Medicine, Cairo University after approval of research and ethics committees.

Children will be recruited into the trial during pre-operative assessment. will be randomly assigned to one of two groups Recruited patients will be randomly allocated by a computer-generated sequence of codes using randomization software (https://www. randomizer.org) into one of the two groups; in a 1:1 ratio (Group R) to receive radial artery cannulation and (Group U) to receive ulnar artery cannulation using ultrasound. The randomization sequence will be concealed in sequentially numbered, sealed opaque envelopes. The sealed envelopes will be opened by an anesthesia nurse immediately before induction of anesthesia.

After induction of anesthesia, modified Allen's test will be done by the ultrasound operator as following:

An Esmarch bandage will be used to exsanguinate the selected hand for cannulation according to the operator preference for 30 seconds, then the operator will apply simultaneous pressure to the ulnar and radial arteries of the chosen limb to occlude them. The bandage will then be released. Next, the pressure over the opposed artery selected for cannulation will be released and the time (in seconds) it takes for color to return to the hand will be measured.

Allen test results will be interpreted as follows:

If color returns to the hand within 5 seconds, the result of the Allen test is negative (normal) and the artery can safely be cannulated.

If color does not return to the palm within 5 seconds, the test result is positive (abnormal). The test will be repeated on the other hand and if the test is positive another site will be selected for cannulation, and the patient will be excluded from the study.

The patient's wrist will be extended over a roll to keep the angle of the wrist unchanged to 30- 45 degrees. After hand washing and sterile gloving; skin will be prepared using alcohol-based chlorhexidine antiseptic in both groups.

Assessment of proposed artery for cannulation using ultrasonography will be performed by one of 2 pediatric anesthesiologists blinded to group allocation who have performed more than 50 ultrasound guided arterial cannulation in pediatrics.

Ultrasound examination will be performed using a hockey stick, high frequency (5-10 MHz) ultrasound probe (S-NerveTM; SonoSite Inc., Bothell, WA, USA).

Image depth will be set to 2- 3 cm and gain settings adjusted to enhance views. Both external force and the angle will be manipulated to optimize images.

The radial artery will be identified in the transverse plane and confirmed with color flow doppler, then in the longitudinal plane by rotating the probe 90 degrees clockwise while maintaining the arterial image. This method will be repeated for the ulnar artery. All antro-posterior (AP) and transverse (T) diameters will be made at the inner (intimal) edge of the vessel. AP diameter will be measured on both transverse and longitudinal images. Cross-sectional area (CSA) will be calculated then as following: π [AP × T] /4. Three measurements will be collected, and the average values will be used for analysis.

Arterial cannulation will be performed using the long axis view (in-plane) technique with a 24 or 22-gauge canulae (Euromed For Medical Industries, S.A.E., Cairo, Egypt) according to the operator preference. Cannulation will be considered complete when the arterial waveform is confirmed on the monitor. If cannulation is unsuccessful within the third attempt or within 10 min, the case will be considered a failure at the chosen artery. After the failure, an alternative site will be used for cannulation and the case will be excluded from the study. The overall procedure time of arterial cannulation is defined as the time interval from the first skin puncture by the canula to confirmation of the arterial waveform on the monitor. After the procedure, the diameter of the cannulated artery and the occurrence of hematoma or vasospasm will be evaluated with ultrasound. Data will be collected by another anesthesiologist who is blinded to the group allocation.

What is being measured

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

  1. Rate of successful cannulation at first attempt

    (the procedure will be classified as successful when the artery is cannulated, and an arterial waveform is recorded within less than 3 attempts and or 15 minutes from the first puncture).

    Measured: 15 minutes

Secondary outcomes (3)
  1. diameters of the arteries before cannulation

    Anteroposterior, transverse diameters and cross-sectional area of the arteries before cannulation

    Measured: preoperative

  2. diameters of the arteries after cannulation

    Anteroposterior, transverse diameters and cross-sectional area of the arteries after cannulation

    Measured: 15 minutes from start of cannulation

  3. incidence of vasospasm

    more than 25% decrease in the artery diameter after cannulation without intra-arterial hematoma.

    Measured: 15 minutes from start of cannulation

Questions about this trial

What is this clinical trial studying?

A study testing ultrasound guided radial versus ulnar artery cannulation in people with Anesthesia and Pediatrics, run by Kasr El Aini Hospital at 1 site in Egypt.

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 7 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 5 Mar 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 Egypt. 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?

Rate of successful cannulation at first attempt (time frame: 15 minutes). 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 5 Mar 2024.
