Three hundred patients were recruited, and ultrasound examination of the SCV was performed. Then, the patients were divided into two groups and SCV catheterization was performed: ultrasound-guided catheterization with the aiming method (group A) and ultrasound-guided catheterization with needle guide (group NG). The success rate, insertion time, number of skin breaks, number of needle redirections, needle visibility and rate of mechanical complications were documented and compared for each procedure. To depict the optimum long-axis view of the SCV, there was a 30\u00b0\u2009\u00b1\u20097.3\u00b0 angle (rotation) between the long axis of the ultrasound probe and the clavicle, while there was a 39\u00b0\u2009\u00b1\u20097.4\u00b0 angle (tilt) between the ultrasound beam plane and the right chest wall. The aiming method was associated with fewer skin breaks [(mean (IQR): 1 (1\u20131) times <jats:italic>vs<\/jats:italic> 1 (1\u20132) times, <jats:italic>P<\/jats:italic>\u2009=\u20090.009], a shorter time to cannulation [(mean (IQR): 39 (32\u201348.5) s <jats:italic>vs<\/jats:italic> 48 (44\u201354.8) s, <jats:italic>P<\/jats:italic>\u2009=\u20090.000] and more needle redirections [(mean (IQR): 0 (0\u20131) <jats:italic>vs<\/jats:italic> 0 (0\u20130), <jats:italic>P<\/jats:italic>\u2009=\u20090.000]. There were no differences between group A and group NG in the overall success rate, first puncture success rate, needle visibility or mechanical complication rate. In conclusion, during ultrasound-guided in-plane catheterization of the SCV, the aiming method provides comparable needle-beam alignment with a lower cannulation time than the needle guide technique.<\/jats:p>","DOI":"10.1038\/s41598-021-88798-0","type":"journal-article","created":{"date-parts":[[2021,5,5]],"date-time":"2021-05-05T10:07:04Z","timestamp":1620209224000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A new method for facilitating ultrasound-guided in-plane cannulation of the subclavian vein: a randomized clinical trial"],"prefix":"10.1038","volume":"11","author":[{"given":"Qingxiang","family":"Mao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haitao","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuangang","family":"Lu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Hu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhen","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maoxiang","family":"Gan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liyong","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Yan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,5,5]]},"reference":[{"key":"88798_CR1","doi-asserted-by":"publisher","first-page":"2479","DOI":"10.1097\/CCM.0b013e318255d9bc","volume":"40","author":"PE Marik","year":"2012","unstructured":"Marik, P.
