Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is the demonstration of an increase of over 50% of the surface visible on ultrasound (mm2) of the axillary vein and subclavian vein in arm abduction (90 °) and external rotation (90 °) with respect to the surface of the subclavian vein along the arm body.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The secondary objective of this study is to investigate the anatomical relationships of these veins with the subclavian artery, the brachial plexus and the pleura, and assess the depth of the vein to the skin. Specifically, the following will be assessed:

* the depth of the vein (mm)
* the length of the minor axis (mm)
* the length of the major axis (mm)
* artery-vein distance (mm)
* vein-pleural distance (mm)
* the distance of the brachial plexus (mm)

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

50 healthy volunteers

The study population consists of healthy volunteers aged 18 to 50 years and without previous surgery, trauma, or thrombosis of the axilla or the shoulder girdle.

Group Type EXPERIMENTAL

Ultrasound measures

Intervention Type PROCEDURE

Ultrasound will be used to measure the surfaces of the axillary and subclavian veins with the arms in different positions. Our goal is to compare the vein surface area available among different vein-position combinations. Our goal does not include testing specific devices.
