Abstract：
UNASSIGNED: We developed a novel photoacoustic needle, which emits ultrasound produced by the photoacoustic effect. This study focused on the most common \"pitfall\" associated with placement during ultrasound-guided vascular access, which is misidentification of the needle tip.
UNASSIGNED: The study was conducted as a prospective cohort study using a questionnaire. The authors intentionally created two successful and one failed ultrasound-guided central venous catheterization videos using the photoacoustic needle on a simulator. Each of these three videos was then split into two movies for viewing, one with standard ultrasound images only and the second including the images from the photoacoustic needle, for a total of six movies.
UNASSIGNED: Participants who were 18 anesthesiologists, 12 residents, and 10 medical students, watched each of the six movies and completed a survey whether the puncture was successful or not. In the results, there was a significant difference in the percentage of correct answers whether the movie depicted successful or failed puncture with and without the photoacoustic ultrasound (p = 0.0001).
UNASSIGNED: The novel photoacoustic needle improved the ability to identify the needle tip on recorded videos. It may have efficacy to prevent serious mechanical complication during the ultrasound-guided vascular access in clinical practice.

摘要：
未经授权：我们开发了一种新型的光声针，发射由光声效应产生的超声波。这项研究集中在最常见的“陷阱”相关的放置在超声引导的血管通路，就是错误地识别了针尖.
UNASSIGNED：该研究是使用问卷调查进行的前瞻性队列研究。作者在模拟器上使用光声针故意创建了两个成功的超声引导的中心静脉导管插入视频，一个失败的视频。这三个视频中的每一个都被分成两部电影观看，一个只有标准的超声图像，第二个包括来自光声针的图像，总共六部电影。
未经评估：18名麻醉师的参与者，12位居民,和10名医学生，观看了六部电影中的每一部，并完成了穿刺是否成功的调查。在结果中，无论电影描述了在使用和不使用光声超声的情况下穿刺成功还是失败,正确答案的百分比都存在显着差异(p=0.0001).
UNASSIGNED：新颖的光声针提高了在录制视频上识别针尖的能力。在临床实践中，它可能具有预防超声引导下血管通路过程中严重机械并发症的功效。
