Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The retroclavicular approach is a variant to this classical technique. Ultrasound probe is positioned initially below the clavicle in a manner similar to the classic approach but is then rotated in a clockwise fashion (right arm) or counter-clockwise fashion (left arm) for about 25-35 degrees. The puncture site is just behind the clavicle at the most lateral point available. If initial entry point is optimal, needle direction is then parallel to ultrasound probe. The final aim and position of block needle is identical to classical approach. Entry point ensures a parallel alignment of the needle and the ultrasound beam, thus enabling almost perfect visualization of both artery, cords and block needle. This is turn optimizes safety, rapidity of technique, efficiency and efficacy.
It is recognized that regional anesthesia is more difficult to perform in obese patients. Anatomic landmarks are harder to localize in this population and ultrasound guidance is more difficult because of the attenuation of the ultrasound beam by adipose tissue. The complication rate of regional techniques is also reported to be higher in the obese patient population.
