Dynamic ultrasound guidance reduces complications associated with central venous catheter placement. However, successful central venous cannulation often remains challenging, particularly in hypotensive patients. The new wire-in-needle (WIN) technique can further increase periprocedural safety. Here, a needle is "preloaded" with a guidewire that is then advanced toward the tip of needle. The vein is then cannulated using long-axis ultrasound guidance. ⋯ This study demonstrates that the WIN technique can be learned quickly and easily by clinicians with various levels of training. In this study, using manikins, it was as successful and safe as the traditional short-axis approach.

Review Meta Analysis
Safety and Effectiveness of Topical Anesthetics in Corneal Abrasions: Systematic Review and Meta-Analysis.
Topical anesthetics are used in the emergency department (ED) to relieve eye pain and allow eye examinations in patients with corneal abrasions. There is concern for delayed corneal healing, which is associated with the long-term use of topical anesthetics, so outpatient use is not recommended. ⋯ There were no differences regarding pain, persistent symptoms, or corneal healing when comparing short-term use of topical anesthetics to placebo in the treatment of corneal abrasion. Data on safety are sparse, and the use of this treatment is currently not supported by evidence.
