Ultrasound-guided supraclavicular cannulation of the right brachiocephalic vein in small XXXX : a consecutive, prospective case series.

@entity21168 @entity1
BACKGROUND: The supraclavicular ultrasound (US)-guided cannulation of the brachiocephalic vein ( @entity21168 ) is one option of central venous line placement in @entity1 . AIM: The aim of this prospective study was to evaluate whether there was an association between the optimum ultrasonographic view as obtained of the entire longitudinal extension of the right @entity21168 and the ease of supraclavicular cannulation when using a strict in-plane technique via a linear US probe in small @entity1 . METHODS: The US probe was placed in the right supraclavicular region. If the optimum obtainable sonographic view presented the entire longitudinal extension of the right @entity21168 demonstrating clearly its path caudally alongside the pleura, it was graded as I. If, however, only a circular view, i.e., the initial part of the right @entity21168 was obtainable via US, it was graded as II. The right @entity21168 was cannulated by advancing a 22-gauge i.v. cannula from lateral to medial strictly under the long axis of the US probe under direct US vision into the vein. RESULTS: Seventy-nine @entity1 weighing between 0.8 and 4.5  kg (Median: 3.4      0.09) were included. In 50 (63.3%) @entity1 , the sonographic view was graded as I and in 29 (36.7%) as II. The proportion of @entity1 successfully cannulated on the first attempt was significantly smaller in @entity1 graded as II, i.e., circular, sonographic view of the right @entity21168 than in @entity1 graded as I, i.e., sonographic view of the entire longitudinal extension of the right @entity21168 (41% vs 90%; chi-square analysis: P  <  0.01). CONCLUSION: The sonographic view obtainable of the entire longitudinal extension of the right @entity21168 resulted in significantly fewer required cannulation attempts.
