简要总结
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)
详细描述
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.

研究组 & 干预措施
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
干预措施: Ultrasound transverse scan (Device)
Ultrasound sagittal scan
Sagittal scan by identifying the first and second ribs and scan medially to depict the C7 transvers process.
干预措施: Ultrasound sagittal scan (Device)
Floroscopic 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.
干预措施: Fluoroscopic technique (Procedure)
结局指标
