About this study
Official title: Relation of the Peripheral Perfusion Index Derived From Pulse Oximetry to Modified Allen's Test in Evaluation of Hand Perfusion
to detect the relation between results of the peripheral perfusion index and modified Allen's test.
Read the detailed description
The modified Allen's test (MAT) is commonly used to assess hand perfusion. Other non-invasive methods including plethysmography, pulse oximetry and duplex ultrasonography are used nowadays. The perfusion index is calculated as the ratio of the pulsatile blood flow to non- pulsatile blood flow in peripheral tissue.
In this study, we will try to detect the relation between results of the peripheral perfusion index and modified Allen's test.

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 6 Jul 2022. 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 Hany M. Osman, M.D. (+201002414591, hanymeo@aun.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Perfusion of the hand using the perfusion index (time frame: Preoperative). 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 6 Jul 2022.
