Summary

In daily life,people protect their tissues against ischemia by constantly changing positions. In situations that cause unconsciousness such as anesthesia,people cannot react to the stress or pressure due to immobility.This prolongation of immobility can lead to reversible or irreversible damage to the tissues.Therefore,not careful positioning in patients undergoing surgery can lead to serious complications.Peripheral nerve disorders are common in clinical practice.Electrodiagnostic studies continue to be the gold standard for the evaluation of nerve disorders.Elastography is a technique that measures the elastic properties of tissues as a new ultrasonography technology.Given the histological changes in diseased peripheral nerves, nerve elastography has begun to be studied as a noninvasive way to evaluate changes in nerve tissue composition.Elastography of the peripheral nerves has rarely been studied.

Primary aim in this study is to compare the elastography values of the brachial plexus in different arm and head positions and to contribute to elucidating the mechanism of nerve damage due to position.American Society of Anesthesiologists (ASA) I-II volunteers between the ages of 18-65 will be recruited to the study.The bilateral brachial plexus of each volunteer will be examined.Participants with upper extremity or cervical trauma, muscle weakness,cervical disc herniation or a history of spine or cranial surgery, neuromuscular disease, clinical diagnosis of brachial plexopathies, hyperlipidemia,diabetes mellitus or radiotherapy history in the cervical region,body mass index\> 35 will not be taken.Before the procedure, the muscle strength of the upper extremity and cervical muscles will be examined and volunteers with muscle weakness will be excluded from the study.Measurements will be made together by two researchers who have at least 5 years of experience in ultrasonography.Measurements will be made in 3 different positions.When the arm and head are in neutral position, the head is turned to the opposite side and the head is turned to the opposite side, the brachial plexus in the supraclavicular region will be visualized by ultrasonography while the arm is in hyperabduction.The area between the upper boundary and the lower boundary of the plexus will be marked, and the values will be taken 5 times consecutively with the share wave elastography method and the elastic modulus,shear wave velocity will be recorded.
