Superficial Forearm Veins Compressibility and WidthNCT04613011
Effect of Double Tourniquet Technique on Ultrasonographic View of Forearm Veins
An observational study of Superficial Forearm Veins Compressibility and Width, run by Bahaa Mohammed Refaie at 1 site in Egypt.
Trial summary
Vein compressibility will be assessed after light pressure applied with the ultrasound probe. Vein compressibility will be graded as 3 (100% compressed), 2 (50-100 compressed), and 1 (less than 50% compressed). After baseline measurements were taken, a proximal tourniquet will be applied to mid-arm. Read more about this study

About this study
Official title: Effect of Double Tourniquet Technique on Width and Compressibility of Superficial Veins of Forearm
Vein compressibility will be assessed after light pressure applied with the ultrasound probe. Vein compressibility will be graded as 3 (100% compressed), 2 (50-100 compressed), and 1 (less than 50% compressed). After baseline measurements were taken, a proximal tourniquet will be applied to mid-arm. Repeated measurements of depth, width, and compressibility will be taken one minute after the tourniquet was applied. Same measurements will be repeated again with second tourniquet applied 1 cm distal to the first tournique.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Vein compressibility will be assessed after light pressure applied with the ultrasound probe. Vein compressibility will be graded as 3 (100% compressed), 2 (50-100 compressed), and 1 (less than 50% compressed). After baseline measurements were taken, a proximal tourniquet will be applied to mid-arm. Repeated measurements of depth, width, and compressibility will be taken one minute after the tourniquet was applied. Same measurements will be repeated again with second tourniquet applied 1 cm distal to the first tournique.

Questions about this trial
What is this clinical trial studying?
An observational study of Superficial Forearm Veins Compressibility and Width, run by Bahaa Mohammed Refaie 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 1 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 28 Sep 2021. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Bahaa Mohammed Refaie, MD (0201026887257, bahaarefaay@med.sohag.edu.gov.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Superficial forearm vein width and compressibility under ultrasonography (time frame: 1 minute after application of one proximal tourniquet). The study lists 2 primary outcomes in all. 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 28 Sep 2021.
