Randomized Controlled Trial Comparative Study
Ultrasound Versus Traditional Palpation to Guide Radial Artery Cannulation in Critically Ill Children: A Randomized Trial.
To identify success rates for radial artery cannulation in a pediatric critical care unit using either palpation or ultrasound guidance to cannulate the radial artery. ⋯ The ultrasound-guided technique could improve the success rate and allow for faster cannulation of radial artery catheterization in critically ill children.

Ultrasound-Guided Fine-Needle Aspiration in the Neck Region Using an Optical See-Through Head-Mounted Display: A Randomized Controlled Trial.
The purpose of this study was to examine the feasibility of an optical see-through head-mounted display (OST-HMD) to improve ergonomics during ultrasound-guided fine-needle aspiration (FNA) in the neck region. ⋯ The OST-HMD improved the practitioners' ergonomics and can be adopted for performing ultrasound-guided interventional procedures in clinical settings.

Number of Weeks Rotating in the Emergency Department Has a Greater Effect on Ultrasound Milestone Competency Than a Dedicated Ultrasound Rotation.
Ultrasound (US) is vital to modern emergency medicine (EM). Across residencies, there is marked variability in US training. The "goal-directed focused US" part of the Milestones Project states that trainees must correctly acquire and interpret images to achieve a level 3 milestone. Standardized methods by which programs teach these skills have not been established. Our goal was to determine whether residents could achieve level 3 with or without a dedicated US rotation. ⋯ To achieve a level 3 milestone, weeks in the ED as a resident were significant for mastering image acquisition and interpretation. A dedicated US rotation did not have a significant effect. A medical school US rotation had a significant effect on image acquisition but not interpretation. Further studies are needed to best assess methods to meet US milestones.

A Randomized Double-Blinded Trial on the Effects of Ultrasound Transducer Orientation on Teaching and Learning Ultrasound-Guided Regional Anesthesia.
Learning ultrasound-guided regional anesthesia skills, especially needle/ beam alignment, can be especially difficulty for trainees, who can often become frustrated. We hypothesized that teaching novices to orient the transducer and needle perpendicular to their shoulders will improve performance on a standardized task, compared to holding the transducer and needle parallel to the shoulders. ⋯ Ultrasound-guided regional anesthesia trainees complete a standardized task more quickly and efficiently when instructed to hold the transducer and needle in an orientation perpendicular to their shoulders.

Randomized Controlled Trial Comparative Study
Comparison of Two Injection Techniques for Intra-articular Hip Injections.
Intra-articular hip joint injections have traditionally relied on the use of image guidance to confirm intra-articular needle placement. Musculoskeletal ultrasound (US) has emerged as a popular tool to aid the clinician in performing intra-articular hip injections. Modern automated injection delivery systems are commercially available and may offer the potential to optimize clinical efficiency while limiting procedural morbidity. The purpose of this study was to compare patient-reported outcomes and clinical efficiency between two US-guided intra-articular hip injection techniques. The hypothesis was that the use of an automated delivery system for US-guided intra-articular hip joint injections would show superiority in clinical efficiency over traditional syringe injections. ⋯ Use of an automated delivery system for US-guided intra-articular hip injections did not show superior efficiency or patient comfort over traditional syringe injections. Intra-articular corticosteroid injections led to clinically and statistically significant improvements in pain and function for patients with intra-articular hip pain, irrespective of the delivery method. Smoking history and female sex were independent predictors of increased pain associated with intra-articular hip joint injections.
