Identification of C7; Evaluations of 2 Sonographic Methods Using a Transverse and a Sagittal Scan.

Not Applicable

Completed

• Conditions: Breastcancer
• Interventions: Device: Ultrasound transverse scan; Procedure: Fluoroscopic technique; Device: Ultrasound sagittal scan

• Registration Number: NCT03012893
• Lead Sponsor: Mahidol University

Brief Summary

To determine the accuracy of two techniques (transverse scan and sagittal scan) using ultrasonography to identify C7 spinous process compare to the fluoroscope (standard technique)

Detailed Description

To identify the accurate level of upper thoracic spine is essential maneuver during breast surgery and axillary node dissection. Palpation C7 spinous process is most common technique using to identify the level. However, the accuracy was lower than 50%. Ultrasonography has been investigated to identify the cervical nerve roots by differentiating the transvers process of C6 and C7. However, there was no study on the accuracy of using ultrasound to identify cervical spine level before.

Arm && Interventions

Group	Intervention	Description
Ultrasound transverse scan	Ultrasound transverse scan	Transvers scan by identifying the C7 transvers process using vertebral artery and absence of anterior tubercle as a landmark and then scan back following articular process, lamina and then find out the spinous process of C7
Floroscopic technique	Fluoroscopic technique	Fluoroscopy image will do on lateral view including all cervical spines and upper thoracic spines. C7 spinous process will be identified by counting down from C1 vertebral body and spinous process.
Ultrasound sagittal scan	Ultrasound sagittal scan	Sagittal scan by identifying the first and second ribs and scan medially to depict the C7 transvers process.

Primary Outcome Measures

Name	Time	Method
the accuracy of identify C7 spinous process	1 day	the accuracy of two techniques (transverse scan and sagittal scan) using ultrasonography to identify C7 spinous process compare to the fluoroscope (standard technique)
