Background: The use of ultrasound during invasive bedside procedures is quickly becoming the standard of care. Ultrasound machine placement during procedures often requires the practitioner to turn their head during the procedure to view the screen. Such turning has been implicated in unintentional hand movements in novices. Google Glass is a head-mounted computer with a specialized screen capable of projecting images and video into the view of the wearer. Such technology may help decrease unintentional hand movements., Objective: Our aim was to evaluate whether or not medical practitioners at various levels of training could use Google Glass to perform an ultrasound-guided procedure, and to explore potential advantages of this technology., Methods: Forty participants of varying training levels were randomized into two groups. One group used Google Glass to perform an ultrasound-guided central line. The other group used traditional ultrasound during the procedure. Video recordings of eye and hand movements were analyzed., Results: All participants from both groups were able to complete the procedure without difficulty. Google Glass wearers took longer to perform the procedure at all training levels (medical student year 1 [MS1]: 193 s vs. 77 s, p > 0.5; MS4: 197s vs. 91s, p ≤ 0.05; postgraduate year 1 [PGY1]: 288s vs. 125 s, p > 0.5; PGY3: 151 s vs. 52 s, p ≤ 0.05), and required more needle redirections (MS1: 4.4 vs. 2.0, p > 0.5; MS4: 4.8 vs. 2.8, p > 0.5; PGY1: 4.4 vs. 2.8, p > 0.5; PGY3: 2.0 vs. 1.0, p > 0.5)., Conclusions: In this study, it was possible to perform ultrasound-guided procedures with Google Glass. Google Glass wearers, on average, took longer to gain access, and had more needle redirections, but less head movements were noted., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Use of bedside ultrasound to guide simple procedures increases safety by allowing real-time visualization of patient anatomy. This article discusses ultrasound guidance for basic procedures including peripheral and central intravenous access, arterial access, suprapubic aspiration, abscess incision and drainage, foreign body identification, and joint arthrocentesis. It reviews the indications and complications of the procedure, advantages of ultrasound guidance, anatomy, and procedural technique., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Ultrasound guidance has become the standard of care for many bedside procedures, owing to its portability, ease of use, and significant reduction in complications. This article serves as an introduction to the use of ultrasonography in several advanced procedures, including pericardiocentesis, thoracentesis, paracentesis, lumbar puncture, regional anesthesia, and peritonsillar abscess drainage., (Copyright © 2014 Elsevier Inc.
